[Cite as: Fadeyi MO (2024). How can balance be ensured in the value delivered to both producers and consumers of indoor air quality solutions? Indoor Air Cartoon Journal, December 2024, Volume 7, #161.]

Note: The Q_t in the producer’s value delivery equation represents the quantity of the product or service available for sales (based on the quantity consumers need to solve their problem). If the producer spent C_t to produce more Q_t than needed by consumers, that act is a source of overproduction waste. The quantity of the product sold/service provided to or paid for by the consumer, (Q_ts), is calculated as: Q_ts = Perceived Quality of Product (Q_pl) × Q_t × Perceived Safety (S_p). The quantity of the product sold/service provided to or paid for by the consumer (Q_ts) refers to the actual amount of the product purchased in a transaction. Q_ts may be a fraction of the quantity of product (Q_t) available for sale, after accounting for the consumer’s perception of quality (Q_pl) and/or perceived safety of the product (S_p) being lower than the level required to solve their problem.

In situations where the quantity of a product purchased by consumers—otherwise known as the quantity sold by the producer (Q_ts)—is not appropriate for solving consumers’ problems because their perceived quality and safety of the product do not align with what is needed in reality, the value experienced by consumers will be compromised. This means that consumers would have invested greater cost for less usefulness, or usefulness that does not correspond to the investment. The value will be further compromised if consumers must invest additional cost and sacrifice greater satisfaction to maintain or upgrade the product in order to achieve the required quality and safety of the required quantity of the product.

The main assumption guiding the above mathematical thinking or mental model is that, in practice, the amount paid by the consumer to the producer—that is, the revenue (R) gained by the producer—is influenced by the consumer’s perceived quality and perceived safety of the product or service offered. The maximum value for each of Q_pl (perceived quality level), Q_t (quantity), and S_p (perceived safety) is normalised to 1. The value of Q_pl and S_p will be less than 1 if consumers perceive them to fall below the threshold needed to address their problem. Similarly, the value of Q_t will be less than 1 if the producer does not make available the full quantity of the product or service required by the consumer to solve their problem.

However, in many cases, the revenue (R) is set or fixed by the producer, even when the consumer’s perception of quality or safety, or the quantity provided, is lower than expected. In such situations, consumers end up paying more for less benefit, and value is compromised. This often reflects a context where practice is not guided by ethical principles.

The computation of each parameter in the two value delivery equations (for producer and consumers) is based on the ratio of the actual situation of the parameter to its expected, planned, or targeted situation. The expected, planned, or targeted situation should ensure an ethical competitive advantage in the market and adhere to international standards and ethical practices for effectively solving consumers’ problems to the greatest extent possible. As a result, the computation for each parameter in the two value delivery equations will range from 0 to 1 or may exceed 1 where applicable. Similar, the computed value delivery for will range from 0 to greater 1, depending on the relationship between the numerator parameters, collectively known as usefulness delivered, and the denominator parameters, collectively known as invested resources.

Value delivered will be equal to when when usefulness delivered is equal to invested resource. Value delivered will be greater than 1 if the usefulness delivered exceeds the resources invested, and less than 1 if the usefulness is less than the resources invested. Value delivered will be equal to 0, representing an absolute waste situation, if no usefulness is delivered despite the investment of resources. However, a situation where no resources are invested in a project, yet usefulness is expected, cannot occur based on the above equations. Such a scenario is undefined because it defies the logical principles of resource utilisation.

When you give value to others, you will find your own success. Many years ago, this is a philosophy that many indoor air quality (IAQ) solution providers (i.e., producers) did not embrace. As a result, many indoor occupants (i.e., consumers) were exposed to high concentrations of indoor air pollutants, leading to a major public health problem, especially among low-income populations, both locally and internationally. The situation struck a chord with a young girl experiencing a personal academic struggle. She decided to embark on a journey to contribute to solving the imbalance in value delivery between producers and consumers, which was causing public health problems. The life journey of this young girl is the focus of this fiction story.

1……………………………….

Romoke Arogundade grew up in a modest apartment on the south side of Chicago, USA, where the aroma of her mother’s cooking mingled with the faint hum of traffic from the street below. Her parents, Mr. Tunde and Mrs. Yetunde Arogundade, were Nigerian immigrants whose lives revolved around hard work and an unwavering belief in the power of education. Romoke was their only child, a decision her parents made for financial and work-related reasons.

Tunde, a cab driver who often worked late into the night, would return home with tired eyes but an unfaltering determination to remind his daughter of the family’s mission. “Romoke,” he would say, his voice calm but firm, “you must learn to create value. When you give value to others, you will find your own success.”

Yetunde, a nurse whose shifts stretched into the early hours, would echo his sentiment as she pulled off her scrubs and sat down to eat whatever scraps of dinner were left. “Your success will be the result of our sacrifices, Romoke,” she would say, her gaze steady despite the exhaustion etched on her face. “Don’t waste it.”

Romoke wanted desperately to make them proud. She could see the toll their hard work was taking—the growing lines on her mother’s face, the long silences that punctuated her father’s evenings after back-to-back shifts. She owed it to them to excel. But school had always been her Achilles’ heel, a battlefield where no amount of effort seemed to yield victory.

In high school, Romoke quickly found herself falling behind her classmates. Maths was a puzzle she could not solve, no matter how many times the teacher explained the steps. Her notes were a chaotic scrawl of formulas and numbers that never seemed to add up. Science was no better. She memorised pages of biology terms late into the night, only to find her mind blank during tests and examinations. English essays, meant to be an exercise in creativity and argument, felt like insurmountable challenges as she struggled to string her thoughts together into coherent paragraphs.

Evenings at home became a cycle of mounting frustration. She would sit at the small dining table, a stack of textbooks in front of her, as Tunde prepared to head out for his night shift. The overhead light flickered faintly, casting a weak glow over her cluttered workspace. Yetunde, in her worn slippers, would hover nearby, stirring a pot of Egusi soup or folding laundry, offering quiet encouragement. “You just need to focus more, Romoke,” Yetunde would say softly. “If you keep at it, you will get there.” “I am focusing!” Romoke would snap, tears welling in her eyes.

She hated the sound of her own voice in those moments, sharp and brittle. But the harder she tried, the more the answers seemed to slip through her fingers, like sand in an hourglass.

Her teachers were sympathetic but frustrated. “Romoke is determined,” one of them wrote on her report card, “but she struggles to maintain consistency. She needs to work harder if she wants to succeed.” That word—inconsistent—hung over her like a dark cloud. She began to dread handing in assignments or getting back test results, knowing the same pattern would repeat: red marks scrawled across the pages, grades that barely scraped by, and the quiet, knowing glances from her classmates.

One particular day in her junior year stood out as the lowest point of her high school experience. It was a maths exam, and the classroom was heavy with the sound of pencils scratching against paper. Romoke stared at the first question, her heart pounding as the numbers seemed to blur and dance on the page. She could feel the seconds ticking away, her classmates flipping pages and jotting down answers while her paper remained painfully blank.

By the time the bell rang, she had answered only three questions, all of which she was certain were wrong. When the teacher handed back the marked exams the following week, Romoke’s heart sank at the sight of a bold 34% circled in red ink at the top of her paper.

At home, she tried to hide her disappointment, shoving the exam deep into her backpack. But Yetunde found it while tidying the living room later that evening. Holding the paper in her hands, she sighed deeply. “Romoke,” she said quietly, “is this how you plan to become the doctor your father dreams of?” Romoke could not meet her mother’s eyes. “I am trying, Mama,” she whispered, her voice trembling. “I’m really trying.” Yetunde did not reply, but the weight of her silence lingered long after she walked away.

As the end of her high school journey approached, Romoke’s parents invested heavily in private tutoring to help her improve her grades and enhance her chances of meeting university entrance requirements. Despite her hard work and her parents’ sacrifices, Romoke managed to complete high school, though her grades fell short of their expectations. Her final report card reflected a mix of Cs and Ds, with a few Bs—sufficient to meet the minimum admission criteria for some community colleges but far from competitive for many universities.

Unfortunately, she performed poorly on her SAT (Scholastic Aptitude Test) examination, further diminishing her prospects of university admission. With her high school grades and SAT results, Romoke’s chances of entering a university seemed out of reach. Her teachers, while commending her determination and hard work, were not surprised by her results.

When the family gathered for her high graduation ceremony, Tunde and Yetunde wore smiles that seemed strained, their pride mingled with unspoken disappointment. Romoke could not shake the weight of their expectations, feeling the silent reproach beneath their warm expressions.

As they posed for photos outside the school, her father placed a hand on her shoulder and said, “This is just the beginning, Romoke. You will do better in a community college and hopefully get admission to a university one day,” his voice carrying an undertone of hope tinged with doubt.

Romoke’s mother’s words, though encouraging, were edged with a firmness that hinted at her disappointment. “You will be a doctor, Romoke. We did not sacrifice so much for you to stop here.

Romoke nodded, forcing a smile, though deep down, self-doubt gnawed at her. Her parents’ faith in her was unwavering despite their disappointment, and she resolved to move forward. With her grades limiting her options, she applied to Crescent Community College, determined to make the most of the opportunity.

After two years of hard work and dedication, she graduated with an Associate of Science degree in Chemistry. Her improved academic performance earned her grades good enough to secure admission into a Chemistry degree programme at Purple State University, bringing her one step closer to fulfilling her parents’ hopes of pursuing a medical degree after graduation.

Becoming a doctor was not just a prestigious goal; it was a symbol of everything her family had sacrificed for her. Her admission to Purple State University was, she thought, a chance to finally prove herself and make her parents proud. Little did she know, her struggles were far from over.

Romoke began her university journey with cautious optimism, eager to pursue her studies in chemistry. However, the reality of the coursework soon proved daunting. Chemistry lectures became an endless torrent of molecular structures and complex equations that left her bewildered.

The laboratory sessions, which she had anticipated with enthusiasm, instead felt like a series of intricate procedures she struggled to grasp. While her peers appeared to navigate assignments effortlessly, Romoke found herself spending countless hours in the library, meticulously poring over the material, only to find her understanding remain frustratingly incomplete.

Despite her relentless efforts, the results were disheartening. Her first round of exams came back with failing grades, each mark on her papers a reminder of her struggle. Determined to improve, she sought every available resource—tutors, study groups, and extra office hours with professors—but the gaps in her understanding only seemed to deepen. By the end of her first year, her GPA had fallen so low that she was placed on academic probation, the notice weighing heavily on her as a stark reminder of the challenges ahead.

By her second year, the situation reached a breaking point. After failing two more major exams, Romoke was formally dismissed from the chemistry programme. The dismissal letter arrived on a grey and somber afternoon, and she sat staring at it for what felt like an eternity.

Breaking the news to her parents that evening was one of the hardest moments of her life. Her father, who had always been her source of strength, looked at her with quiet resignation. “Romoke,” he said gently, his voice heavy with concern, “what do you plan to do next?”

For three years, Romoke drifted through life in a haze of disappointment and monotony. Her days blurred into a routine of clocking into dead-end jobs—waitressing at a diner where customers barely looked her in the eye, scanning groceries at a supermarket where the beeping of the register felt endless, and delivering groceries to strangers’ doorsteps in the biting cold.

These jobs kept her moving, but they did little to quiet the persistent ache in her chest. She carried the weight of failure everywhere she went, a silent reminder that she had let her parents, and herself, down.

Her once warm relationship with her parents had grown distant, fractured by unspoken disappointment. Mealtime conversations that used to be filled with laughter and dreams of the future were now reduced to brief exchanges about her schedule or the weather. The silence cut deeper than words ever could, a constant reminder of the profound difference between the life her parents had envisioned for her and the one she was living.

One bitterly cold evening, as the wind howled through the streets, Romoke found herself delivering groceries to a low-income housing complex. The building was in disrepair, its peeling paint and broken windows barely keeping out the biting chill. She climbed the dimly lit staircase, her breath visible in the frosty air. At the door, she knocked softly, waiting for an answer.

When the door opened, the smell hit her first—a sharp, suffocating mix of mould and harsh chemical fumes. The air felt heavy, almost unbreathable. Inside, the small apartment was dimly lit, the wallpaper peeling in damp corners. A young boy sat hunched in the corner, his thin frame trembling as he coughed violently. His mother, an exhausted woman with tired eyes and a trembling voice, apologised as she took the bags. “I’m sorry,” she said, wringing her hands. “His asthma’s been bad lately, and the doctor says we need an air purifier, but I cannot afford one right now.”

Romoke froze, unsure of what to say. She watched as the boy struggled for breath, his small hand clutching his chest. The helplessness in the mother’s eyes mirrored the pain Romoke had seen in her own mother’s gaze years ago—when she was expelled from the university and shattered the dreams her parents had built for her.

As she left the apartment, the icy wind outside felt like a reprieve from the suffocating air inside, but her mind was anything but calm. That night, she could not sleep. The boy’s cough echoed in her thoughts, his mother’s words replaying in her mind. On a whim, she opened her laptop and began researching indoor air quality (IAQ) and health effects.

What she discovered shocked her. Poor IAQ was a silent crisis affecting millions, disproportionately harming low-income families. It was linked to respiratory diseases, asthma, and even throat cancer. Yet the solutions available were either exorbitantly priced or ineffective. Families like the one she had just met were trapped, unable to afford high-quality air purifiers or air filters, while the businesses producing them seemed more concerned with profit margins than accessibility.

The more Romoke read, the angrier she became. She found a troubling pattern: businesses either priced their products so high that only wealthier families could afford them or cut costs so drastically that their solutions became ineffective. In both cases, the people who needed help the most were left to suffer. It was not just a failure of business; it was a failure of humanity.

Romoke’s anger turned into an intense determination. The imbalance she read about the IAQ industry reminded her of her own struggles—systems that seemed designed to prioritise efficiency or profitability over the needs of the people they were meant to serve.

Despite the sacrifices her parents had made, the academic structures she relied on had failed to account for students like her. Similarly, the IAQ industry focused either on maximising profits for producers or on creating cheap, substandard products for consumers—leaving both sides vulnerable and dissatisfied.

Furthermore, this was a time when poor IAQ was prevalent in the country, leading to widespread poor health, low task performance, and reduced productivity. This was also a period when consumers of IAQ solutions believed that IAQ providers (i.e., the producers) were exploiting them and were reluctant to engage their services. Consumers felt that they would invest significant resources (both in terms of cost and satisfaction) but receive little or no value in return.

This realisation struck a deep chord in her. It was not just about clean air or financial success; it was about fairness. It was about creating systems that worked for everyone—ensuring that IAQ producers could sustain their businesses while delivering effective, affordable solutions to the people who needed them most.

That night marked the beginning of something new for Romoke. The woman who had spent years drifting in disappointment found herself anchored by a purpose she could not yet define but knew she had to pursue.

2……………………………….

Romoke had discovered her purpose, and for the first time in her life, every step forward felt certain. Returning to school was not just a decision; it was a personal vow to turn her struggles into something meaningful. She enrolled in a four-year Bachelor of Engineering (BEng) programme in Engineering with Business at Metropolitan State University, USA. The programme seamlessly blended technical rigour with the analytical depth of business, and Romoke embraced it with a determination she had never known before.

Her passion for understanding systems—how things worked and how they could be improved—drove her to excel. In addition to her core engineering modules, she chose elective modules in IAQ, business, economics, statistics, and public health. She also took university-level modules on design thinking, sustainability, critical and reflective thinking, communication, and digital empowerment. She saw the connections between these fields as pieces of a puzzle that could solve real-world problems.

Motivated by her newfound purpose, Romoke asked questions relentlessly, seeking not just to memorise concepts but to truly understand how they related to one another. Her enhanced questioning capability pushed her thinking to new heights, enabling her to learn effectively, generate knowledge, develop deep understanding, and apply her skills proficiently.

By the time Romoke graduated, her hard work had paid off spectacularly. She achieved Summa Cum Laude (meaning “with highest honours”), emerging as the top graduating student in her programme. At the graduation ceremony, her parents, Tunde and Yetunde, sat in the front row, their faces glowing with pride. Tunde, dressed in a crisp grey suit, kept dabbing his eyes with a handkerchief. Yetunde, in a vibrant Ankara dress, leaned forward in her seat, unable to contain her joy.

As Romoke’s name was called and she walked across the stage to accept her degree and several awards, the hall erupted in applause. From their seats in the audience, Yetunde whispered, “Look at her, Tunde. Our Romoke. She’s done it.” Tunde nodded; his face radiant with pride.

When the ceremony ended, Romoke found her parents waiting for her outside the hall. They enveloped her in an emotional embrace. “You didn’t just make us proud, Romoke,” Tunde said, his voice trembling. “You showed us what it means to rise, no matter how many times you fall.” Yetunde kissed her daughter’s forehead, tears streaming down her cheeks. “We always knew you had it in you,” she said. “Thank you for proving us right.

Despite her remarkable achievements, Romoke stayed grounded, focusing on the practical steps ahead. She envisioned a future where she would first gain industry experience, learning the ropes, and eventually launch her own company dedicated to making IAQ solutions affordable and accessible for low-income families—a cause close to her heart. But fate, as it often does, had a way of steering her path in unexpected directions.

Her final-year dissertation supervisor, Dr. Harlan, had seen something extraordinary in her. Through countless discussions, research sessions, and late-night problem-solving, he had come to admire not just her intellect but her unwavering commitment to finding solutions that mattered.

A few days before the end of her undergraduate studies, during a quiet moment in his office with the door wide open, he looked at her with a thoughtful expression. “Romoke,” he said, leaning forward, “you have a gift—a rare ability to connect ideas and people. Have you ever considered pursuing a PhD? With your talent, applied research could allow you to impact lives on a scale far greater than you can imagine.”

His words hung in the air, planting a seed of possibility in Romoke’s mind. She had always been focused on practical solutions, but now, for the first time, she began to see how research might amplify her mission in ways she hadn’t yet considered. It was not just a suggestion—it was an invitation to dream bigger.

At first, Romoke hesitated. A PhD seemed daunting, and she wanted real-world experience. But Dr. Harlan, ever persuasive, explained how research rooted in practical applications could lead to innovations that would change lives on a global scale. “You’re not just capable of making a difference, Romoke,” he said. “You’re capable of leading the way.”

After much reflection, Romoke decided to take the leap. Armed with a glowing recommendation letter from Dr. Harlan, a meticulously crafted research proposal, an impressive performance during her PhD application interview, and a stellar academic record—including a journal article in a prestigious publication and a well-received conference paper—she applied to California Technological University, USA, one of the most esteemed universities in the world. Her application not only showcased her achievements but also highlighted the clarity and purpose of her vision, making her a standout candidate.

When the acceptance letter arrived, Romoke’s hands trembled as she tore it open, her heart racing with anticipation. As her eyes scanned the words confirming her admission, a surge of emotion overtook her. She sat frozen for a moment, tears streaming down her face as the enormity of the achievement sank in. Her journey had been anything but ordinary—marked by setbacks, self-doubt, and an unwavering resolve—yet here she was, preparing to embark on a PhD at one of the world’s most prestigious institutions.

When she shared the news with her parents, their reaction was immediate and overwhelming. Tunde’s booming laughter filled the room as he wrapped his daughter in a proud, jubilant embrace. “Our Romoke! You’ve done it!” he exclaimed, his voice brimming with pride. Yetunde joined them, pulling Romoke into her arms. “You are going to do great things, my dear,” she said, her voice steady despite the tears in her eyes. “You are going to be a doctor. And we will be with you every step of the way.”

Later that evening, as the family celebrated the news, the conversation took a reflective turn. Tunde, with a warm smile, said, “Romoke, you’ve accomplished so much, and we couldn’t be prouder. But you’re already 30 now—perhaps it’s time to think about marriage, too? Maybe even a little one during your PhD?” Yetunde nodded in agreement, her tone both encouraging and light-hearted. “We just want to see you happy in every way, my dear. You can balance it all, if that’s what you want.”

Romoke smiled, touched by their words but resolute in her own plans. “I hear you, Baba, Mama,” she said gently. “Marriage and children are important, and I do want those things eventually. But right now, I need to focus on this PhD. It’s a huge step for me, and I want to give it my all. When the time is right, I promise, I wll think about it.”

Her parents exchanged a glance, their expressions a mix of understanding and pride. “That’s our Romoke,” Tunde said, his voice warm. “You’ve always known your path, and we will always be here to support you—no matter what you decide.”

For Romoke, this moment was more than a personal triumph. It was another testament to her family’s sacrifices, another reflection of the purpose she had fought so hard to reclaim, and an affirmation of her determination to create systems that worked for everyone. This moment was hers, but it was also theirs—a shared victory born of love, faith, and resilience. Together, they had reached this milestone, and together, they would embrace whatever came next.

A few months later, Romoke travelled to California to start her PhD journey with full determination to excel. The overarching research questions for her PhD research were: (i) What factors influence the ability of indoor air quality (IAQ) solution producers to balance the value they gain with the value they deliver to consumers, and how do these factors affect public health and business sustainability? (ii) How can producers optimise their business models to ensure equitable value delivery to consumers while sustaining their own value and fostering innovation? (iii) How can advancements in digital technologies and data-driven approaches enable IAQ solution producers to enhance value delivery to consumers while sustaining their own value through optimised business models?

These research questions informed the objectives for her PhD research. The objectives were: (i) To identify and analyse the factors that influence the ability of indoor air quality (IAQ) solution producers to balance the value they gain with the value they deliver to consumers, and to assess the impact of these factors on public health and business sustainability. (ii) To investigate how IAQ solution producers can optimise their business models to ensure equitable value delivery to consumers while sustaining their own value and fostering innovation. (iii) To explore and evaluate how advancements in digital technologies and data-driven approaches enable IAQ solution producers to enhance value delivery to consumers while sustaining their own value through optimised business models.

The problem statement that informed research question 1 and objective 1 is: There is a gap between the expected ability of IAQ solution producers to identify and address the factors influencing a balance in value delivery (e.g., profitability, consumer affordability, and accessibility) and their current performance, where many producers struggle to maintain this balance. This inability exacerbates public health risks, such as exposure to indoor air pollution, and threatens the long-term sustainability of IAQ solution providers.

The goal the research question 1 and objective 1 wish to achieve is: To analyse the factors contributing to the imbalance and assess their impact on both public health and business sustainability to establish a foundation for effective interventions.

The problem statement that informed research question 2 and objective 2 is: There is a gap between the expected ability of IAQ solution producers to deliver equitable value through their business models—balancing the value gained by consumers (e.g., affordable and effective solutions) with the value gained by producers (e.g., sustainability and innovation)—and their current ability to achieve this balance.

This gap limits the capacity of IAQ producers to provide solutions that maximise consumer and producer value simultaneously. The goal the research question 2 and objective 2 wish to achieve is: To develop business model frameworks that enable IAQ producers to balance the value delivered to consumers with the value they gain, ensuring fairness, accessibility, and long-term sustainability.

The problem statement that informed research question 3 and objective 3 is: There is a gap between the expected ability of IAQ producers to integrate digital technologies and data-driven methods (e.g., AI, IoT, and big data analytics) into their business models to balance value delivery to consumers with value retention for themselves and their current limited adoption of these tools.

This gap reduces the potential to achieve sustainable business performance, consumer affordability, and public health improvements. The goal the research question 3 and objective 3 wish to achieve is: To develop business model strategies that integrate digital technologies and data-driven approaches, enabling producers to achieve a balance between value delivery to consumers and value retention for themselves while addressing public health outcomes.

Romoke’s PhD research was applied in nature. With a generous applied research grant secured through the support of her PhD supervisor, Professor Ian Ferguson, Romoke led the research in her capacity as a PhD researcher under Professor Ferguson’s supervision. Summaries of Romoke’s PhD research methods and results, which addressed the research questions and objectives, are provided below.

Research Methods

Research Methods for Objective 1:

Research Question: What factors influence the ability of IAQ solution producers to balance the value they gain with the value they deliver to consumers, and how do these factors affect public health and business sustainability?

This aspect of the study was designed to comprehensively explore the factors influencing the ability of IAQ solution producers to balance the value they gain with the value they deliver to consumers. These solutions of interest in this research include air filtration devices, air purification technologies, and IAQ monitoring systems that provide real-time data on indoor pollutant levels.

A mixed-methods exploratory design was employed, integrating qualitative and quantitative approaches to provide a thorough understanding of the issue. The methodology involved systematic data collection, including a literature review, semi-structured interviews, and secondary data analysis.

These data sources were subsequently examined through rigorous qualitative and quantitative analysis techniques. This multi-faceted approach allowed the study to address the complexity of the research problem effectively.

— Research Design —

The study employed a mixed-methods exploratory design, a research strategy combining qualitative and quantitative approaches to comprehensively examine the dynamics of value delivery in IAQ solutions. This design was selected because existing literature on the subject is limited, necessitating an approach that allows for the generation of initial insights through qualitative methods, which can then be tested and validated quantitatively.

The exploratory nature of this design enabled the identification of critical factors and relationships influencing the balance of value delivery, which might not have been apparent through a purely qualitative or quantitative approach alone.

The mixed-methods design was particularly valuable in addressing the dual complexity of the research problem: understanding the socio-economic, process, operational, and sustainability challenges faced by producers while also accounting for consumer expectations and public health outcomes.

By integrating these perspectives, the research provided a nuanced understanding that combined subjective, context-specific insights with objective, and empirical evidence. This comprehensive perspective not only enhanced the depth of the findings but also improved their applicability across diverse stakeholders.

— Data Collection —

Data collection for this study was structured into three main components: a systematic literature review, semi-structured interviews, and secondary data analysis. These components were selected to ensure triangulation of findings, capturing distinct yet complementary types of evidence.

Systematic Literature Review: The systematic literature review served as the foundation for the study, identifying key theoretical frameworks, concepts, and factors relevant to value delivery in IAQ solutions and comparable industries. The review followed a meticulous protocol to ensure rigour and reproducibility. Major academic and professional databases, including Scopus, Web of Science, PubMed, and Google Scholar, were utilised to source relevant literature.

The search strategy was designed using carefully selected keywords, such as “Indoor Air Quality (IAQ) solutions,” “value delivery,” “process management”, “lean thinking”, “lean waste”, “business sustainability,” and “public health impacts.” To ensure relevance, the inclusion criteria were limited to peer-reviewed articles, policy documents, and industry reports published within the last 15 years, while non-empirical studies or those unrelated to IAQ were excluded.

The literature review enabled the identification of recurring themes, such as affordability, accessibility, innovation, and regulatory challenges, which informed the subsequent data collection phases. It also highlighted gaps in the existing body of knowledge, particularly in understanding the interplay between producer profitability, consumer satisfaction, and public health outcomes.

Semi-Structured Interviews: Semi-structured interviews were conducted to gather in-depth qualitative insights from a range of stakeholders, ensuring that diverse perspectives were included. Stakeholders included IAQ solution producers, consumers, policymakers, and industry experts.

Producers provided valuable input on challenges related to balancing profitability and consumer needs, while consumers shared their expectations regarding affordability, accessibility, and the effectiveness of IAQ solutions. Policymakers offered insights into regulatory frameworks shaping the IAQ industry, and experts discussed broader market trends and emerging technological advancements.

Participants were recruited using purposive sampling to ensure representation from diverse backgrounds and sectors. Recruitment strategies included outreach through industry networks, professional organisations, and academic institutions. Each interview lasted between 60 and 90 minutes and was conducted in-person or via video conferencing. Audio recordings of the interviews were transcribed verbatim, enabling comprehensive analysis.

Secondary Data Collection: Secondary data collection involved gathering quantitative data from IAQ producers to complement the qualitative insights obtained from interviews. Sources included publicly available sustainability reports, industry analyses, and health-related datasets.

Reports on value determinants for the producers of a solution were examined. The determinants examined were (i) satisfaction level gained by the producer of a solution, (ii) Revenue (R) gained by the producer from selling or transaction the developed solution, (iii) satisfaction level sacrificed by the producer in producing the solution, (iv) cost (C_t) incurred by the producer in producing and selling to or transaction the solution with the consumer.

Satisfaction level gained by the producer of a solution is a function of comfort (C_f), convenience (C_v), and awareness (A_w) gained by the producer from the revenue from selling or transaction the developed solution. The revenue gained from the solution sold or transaction is a function of the price paid by the consumer, customer’s perceived quality (Q_pl) of the solution in solving their problem, customer’s perceived safety (S_p) of the solution – i.e., it will not cause more problem when using it to solve the problem at hand, and quantity (Q_t) of the solution or products available for sales to consumers.

The price paid by the consumer to the producer is a function of the cost of the quantity of the solution sold or transaction (C_tq), profit margin for the producer based on the quality and safety achieved for a unit quantity of the solution (M), and differentiation input reflecting what customers are realistically willing to pay, considering the economic and market conditions (D).

Satisfaction level sacrificed by the producer in producing the solution. This satisfaction level is a function of comfort (C_fs), convenience (C_vs), and awareness (A_ws) sacrificed – i.e., cognitive ability the producers sacrifice in the process of producing and selling to or transaction the solution with the consumer.  The developed equation for determining the value gained by the producer is given below:

To emphasis, the Q_t in the producer’s value delivery equation represents the quantity of the product available for sales (based on the quantity consumers need to solve their problem). The quantity of the product sold (Q_ts) is calculated as: Q_ts = Perceived Quality of Product (Q_pl) × Q_t × Perceived Safety (S_p). Additionally, the computation of each parameter in the two value delivery equations is based on the ratio of the actual situation of the parameter to its expected, planned, or targeted situation.

The expected, planned, or targeted situation should ensure an ethical competitive advantage in the market and adhere to international standards and ethical practices for effectively solving consumers’ problems to the greatest extent possible. As a result, the computation for each parameter in the producer and consumer value delivery equations will range from 0 to 1 or may exceed 1 where applicable. Similar, the computed value delivery for will range from 0 to greater 1, depending on the relationship between the numerator parameters, collectively known as usefulness delivered, and the denominator parameters, collectively known as invested resources.

Value delivered will be equal to when when usefulness delivered is equal to invested resource. Value delivered will be greater than 1 if the usefulness delivered exceeds the resources invested, and less than 1 if the usefulness is less than the resources invested. Value delivered will be equal to 0, representing an absolute waste situation, if no usefulness is delivered despite the investment of resources. However, a situation where no resources are invested in a project, yet usefulness is expected, cannot occur based on the producer and consumer value delivery equations. Such a scenario is undefined because it defies the logical principles of resource utilisation.

Reports on value determinants for the consumers of a solution were examined. The determinants examined were (i) satisfaction level gained by the consumer of a solution, (ii) performance level of the solution in solving the consumer’s problem, (iii) satisfaction level sacrificed by the consumer, (iv) cost incurred by the consumer.

Satisfaction level gained by the consumer of a solution is a function of comfort (C_f), convenience (C_v), and awareness (A_w) gained by the consumer from the extent to which the consumer’s problem is solved. Performance level of the solution in solving the consumer’s problem is a function of quality (Q_l), quantity (Q_t) and safety (S) of the solution consumed by the consumers. Satisfaction level sacrificed by the consumer in acquiring and using the solution to solve their problem to the level to which it is solved.

Satisfaction level sacrificed by the consumer is a function of comfort (C_fs), convenience (C_vs), and awareness (A_w) sacrificed in the process of exploring solution options, acquiring, and using the solution to solve their problem. Cost incurred by the consumer in the process of exploring solution options, acquiring, and using the solution to solve their problem. The developed equation for determining the value delivered to consumers is given below:

Additionally, public health implications of no striking balance between value gained by the producer of a solution and value delivered to each consumer of the solution. The following were considered in the value gained by the producer of a solution and value delivered to each consumer of the solution. In a scenario where the perceived safety or quality of a solution by consumers is non-existent (i.e., zero), the solution becomes unsellable or unacceptable, resulting in no revenue or value gained. Similarly, when the quantity of a solution purchased equals zero, no revenue or value will be gained, regardless of its safety or quality.

This interpretation aligns with the premise that all parameters in the equation are essential and must coexist to generate revenue and value for the producer. The quality, quantity, and safety of a solution are functions of its performance (quality, quantity, and safety) level in addressing the consumer’s problem. Zero in any performance-level criterion will render the value delivered to a consumer zero.

It is also important to note that the ratio of the actual computed to expected number for each parameter in the equations can be greater than 1, except for those related to gained comfort, convenience, and awareness. When a consumer’s problem is completely solved, and each gained satisfaction parameter equals 1, any additional cost or satisfaction parameters sacrificed by the consumer to consume more Q_t​ and process Q_l​ and S represent over-consumption and extra-processing waste, respectively.

The value delivery parameters for producers and consumers examined in the secondary data collection were also address in the semi-structured Interviews The combination of qualitative and quantitative data sources allowed for a holistic understanding of the dynamics influencing value delivery. By triangulating findings from interviews, literature, and secondary data, the study ensured robust and credible conclusions.

— Data Analysis —

The data analysis phase was divided into two main parts: qualitative analysis of semi-structure interview data and quantitative analysis of secondary data. These analyses were conducted sequentially to build on the insights generated at each stage.

Thematic Analysis: Thematic analysis was employed to analyse qualitative data obtained from interviews. This method involved familiarising the researcher with the data through repeated readings of transcripts, followed by systematic coding using NVivo software.

Individual codes were categorised into broader themes, such as affordability, innovation, sustainability, regulatory barriers, public health implication, and usefulness of gained from the solution and invested resources – for producers and consumers.

The relationships between these themes were then visualised using thematic maps, which illustrated the interdependencies among different factors influencing value delivery – i.e., the ratio of usefulness of gained from the solution to invested resources – for producers and consumers.

To enhance the reliability of the findings, member checking was conducted. In this process, participants reviewed and validated the identified themes, ensuring that the analysis accurately represented their perspectives. Additionally, insights from the thematic analysis were cross verified with the literature review findings to enhance the credibility and depth of the conclusions.

Regression Analysis: Quantitative analysis began with regression analysis, which was applied to the secondary data to explore relationships between specific factors and measurable outcomes.

Dependent variable is the value delivery. Independent variables are the parameters in the equations leading to the value delivery computation. This analysis provided a clear understanding of the relative importance and significance of each factor, helping to identify key drivers of value delivery balance.

Structural Equation Modelling (SEM): To further explore the complexity of these relationships, structural equation modelling (SEM) was utilised. SEM enabled the simultaneous analysis of multiple variables and was particularly useful for testing the conceptual framework developed during the literature review and thematic analysis.

The analysis involved confirmatory factor analysis (CFA) to validate latent variables, such as “consumer value” “producer value”, “producer sustainability,” “public health”, and structural path testing to assess the relationships among these variables.

SEM was performed using software tools such as AMOS (Analysis of Moment Structures) and LISREL (Linear Structural Relations). The use of both software tools allowed cross-checking of results for consistency and robustness. This strengthens the validity of the findings.

Additionally, the validity of the model was assessed through goodness-of-fit indices, including the Root Mean Square Error of Approximation (RMSEA) and Comparative Fit Index (CFI). This analysis provided a comprehensive and nuanced understanding of how various factors interacted to influence value delivery balance.

Research Methods for Objective 2:

Research Question: How can producers optimise their business models to ensure equitable value delivery to consumers while sustaining their own value and fostering innovation?

This aspect of the study was carefully designed to investigate how IAQ solution producers for air filtration devices, air purification technologies, and IAQ monitoring systems can optimise their business models to deliver equitable value to consumers while maintaining their own sustainability and fostering innovation.

To achieve this, the study adopted an action research design complemented by a systematic and iterative data collection process involving focus groups, case studies, and consumer surveys. Action research is a participatory approach that emphasises collaboration between researchers and stakeholders to co-develop, test, and refine real-world solutions.

This design was particularly suitable for this study as it allowed for the simultaneous exploration of theoretical insights and the practical application of business models in real-world contexts. Action research is characterised by its iterative nature, which involves cycles of planning, implementation, observation, and reflection.

These methods were further enhanced through rigourous data analysis using business model canvas analysis and multi-criteria decision analysis (MCDA). This comprehensive approach ensured the development and evaluation of innovative business models tailored to address the challenges and opportunities faced by IAQ producers.

It is important to note that the research does not aim to develop entirely new IAQ solutions of interest. Instead, the focus is on testing and optimising business models for existing IAQ solutions that are already commercially available or in use. Considering this constraint in this study, the quality and safety of solutions used for this study were proved to be excellent by both their consumers and producers. The solutions were also proved to be excellent in reducing indoor air pollutants concentrations.

The study explores how these solutions can be delivered more effectively to balance consumer value—such as affordability, accessibility, and health benefits—with producer sustainability. In this context, the action research design involves co-developing and testing business models, not the IAQ technologies themselves.

— Research Design —

During the planning phase, engagement was made with IAQ producers, consumers, and relevant stakeholders to design business models aimed at enhancing the accessibility and adoption of existing the solutions of interest. These models encompassed strategies such as pricing structures, distribution methods, service frameworks, and collaborative partnerships to address issues of affordability, accessibility, and market gaps.

Different business models are applied across diverse IAQ producers operating in varied contexts. For instance, one IAQ producer may trial a pay-as-you-use subscription model for their monitoring systems, while another might expand collaborative partnerships with local community organisations to improve the affordability and accessibility of portable air purifiers.

Although these implementations are not compared to an explicit “no-intervention” control group, the performance of the new business models is evaluated against the producers’ baseline operations, which serve as an internal reference point.

For example, a producer trialling a pay-as-you-use model for IAQ monitoring systems will provide pre-implementation data on adoption rates, revenue trends, and customer satisfaction. During and after the trial period, the same metrics are monitored and compared to assess the impact of the new business model.

Another example is a producer working with community organisations to expand access to portable air purifiers will document pre-trial distribution rates, sales volumes, and geographic reach. Post-implementation data will reflect the success of the collaborative approach in enhancing accessibility, adoption rates, and customer feedback.

By comparing the outcomes of these business model trials to pre-existing data (baseline operations), the research generates insights into the effectiveness and feasibility of the proposed approaches.

The lack of a formal control group does not diminish the study’s value, as the action research methodology prioritises practical, iterative testing and continuous refinement in real-world settings. The flexibility of this approach ensures the findings remain directly applicable and responsive to the operational realities of IAQ producers.

In the observation phase, data were systematically collected to evaluate the feasibility, impact, and overall performance of the business models under trial. Key performance indicators included consumer adoption rates, producer profitability, customer satisfaction, and the overall improvement in accessibility to IAQ solutions. The primary aim of this phase was to assess the effectiveness of each business model and identify areas requiring refinement or modification.

The reflection phase focused on analysing the data collected during implementation and incorporating feedback from stakeholders, including IAQ producers, consumers, and policymakers. This analysis enabled the identification of the strengths and weaknesses within the models and make iterative refinements based on observed outcomes.

The action research approach ensured that the business models remained adaptable and responsive to real-world challenges, ultimately producing actionable recommendations for improving value delivery without necessitating the development of new technological solutions.

The participatory nature of the research design facilitated meaningful contributions from all stakeholders, ensuring that the resulting business models were practical, realistic, and aligned with market and consumer needs.

— Data Collection —

Data collection was meticulously planned to capture insights from multiple perspectives on how to optimise business models for these IAQ solutions. The process involved focus groups, case studies, and consumer surveys, with each method tailored to explore specific aspects of the research problem, ensuring a holistic understanding of the dynamics within the IAQ industry.

Focus Groups: Focus groups served as a collaborative platform for designing business models for IAQ solutions, such as portable air purifiers, smart air monitors, and cost-effective filters. The sessions brought together a range of key stakeholders, including IAQ solution producers, policymakers, technology developers, industry analysts, and consumer advocacy representatives.

The diverse composition of participants allowed for the integration of technical, regulatory, and market-driven perspectives to address both producer and consumer needs.

Each session was facilitated to ensure discussions remained structured and productive. The sessions began with a presentation of the challenges and opportunities identified in the existing literature, including issues such as limited affordability for low-income consumers, slow adoption. Participants were then introduced to initial business model concepts, which they discussed, critiqued, and refined collaboratively.

Topics of discussion included strategies to balance affordability for consumers with producer profitability, approaches to fostering innovation in product development (e.g., low-maintenance filters or cost-effective sensors), and methods for incorporating consumer feedback into IAQ solution designs.

The discussions provided rich qualitative data, offering insights into potential barriers and enablers of business model success, while guiding the development of prototypes to be tested in the next phase.

Case Studies (Implementation): The case study method was employed to test the proposed business models for IAQ solutions in real-world settings, providing practical insights into their feasibility and performance. The solutions evaluated in this phase included portable air purifiers with varying filter efficiencies, real-time indoor air monitoring devices, and air filtration units.

To ensure diversity, case studies included IAQ producers differing in company size, product focus, and geographic reach in the country. Small and medium enterprises (SMEs), as well as larger IAQ companies, were selected to explore how varying business contexts influenced the effectiveness of different models. For example, some companies focused on affordability-driven strategies aimed at middle- to low-income markets, while others prioritised premium solutions with advanced technological features for high-income consumers.

During the implementation phase, each participating company adopted one or more of the proposed business models for a specified period, typically ranging from six to twelve months. The research team closely monitored the implementation process, systematically documenting challenges, adaptations, and observed outcomes.

These case studies provided empirical evidence on the strengths and weaknesses of each proposed model. This phase of the research highlighted areas for refinement, such as balancing production costs with consumer affordability while maintaining product quality and safety and health outcomes.

Consumer Surveys: Consumer surveys were conducted to complement producer-focused data and to gather critical feedback on the perceived value, accessibility, and affordability of the tested IAQ solutions. These surveys targeted users of air purifiers, portable filtration devices, and smart air monitoring systems to assess their experiences, satisfaction, and willingness to pay for such technologies.

The surveys were designed to capture both quantitative and qualitative insights. Questions addressed the parameters in the value delivery equation for the consumers. a. Open-ended questions allowed respondents to share additional perspectives on unmet needs, such as the desire for maintenance-free solutions or lower operational costs (e.g., energy-efficient units).

To ensure representation across diverse socio-economic groups, participants were recruited from varying income levels and regions through company databases, community networks, and social media platforms.

Surveys were administered in both online and physical formats to maximise accessibility and participation. Special efforts were made to include respondents from vulnerable populations, such as families living in urban areas with high outdoor pollution but no access to advanced IAQ systems.

The data collected from these surveys provided valuable insights into consumer preferences, expectations, and barriers to adoption. This information enabled a thorough evaluation of the alignment between producer strategies and consumer needs.

— Data Analysis —

The collected data was analysed using two complementary techniques: business model canvas analysis and multi-criteria decision analysis (MCDA). These methods enabled a systematic evaluation of the proposed business models, ensuring a rigorous and transparent assessment of their effectiveness.

The data analysis was done in the context of ensuring how value delivery to the producers is balanced with value delivery to the consumers. The developed value delivery equations for the producers and consumers were used in the analysis.

Business Model Canvas Analysis: The business model canvas provided a structured framework for evaluating the alignment of consumer and producer value in each tested business model. Key components of the canvas, such as value propositions, customer segments, revenue streams, and cost structures, were analysed using data from focus groups, case studies, and consumer surveys.

It assessed whether the models met consumer needs while delivering value to producers, ensured pricing strategies balanced affordability with profitability, and analysed operational cost efficiency to optimise resources, maintain quality and safety, and enhance both consumer accessibility and producer sustainability. This detailed assessment identified strengths and weaknesses in each business model, providing actionable insights for refinement and improvement.

Multi-Criteria Decision Analysis (MCDA): MCDA was employed to identify the most effective business model based on predefined performance indicators. This method allowed for the systematic evaluation of trade-offs between competing objectives, such as affordability, profitability, accessibility, and innovation capacity.

The analysis followed a structured approach. First, performance indicators were selected, aligning with the study’s objectives and stakeholder priorities. Next, each business model was scored on these indicators using data from case studies and surveys, with stakeholders assigning weights to reflect the indicators’ importance. Finally, scores and weights were combined to compute an overall performance score for each model, enabling their ranking.

The top-performing model was identified based on these rankings and subjected to further refinement to ensure its alignment with both consumer needs and producer sustainability objectives. MCDA provided a transparent and rigourous evaluation process, ensuring that the final recommendations were grounded in empirical evidence and stakeholder input.

Research Methods for Objective 3:

Research Question: How can advancements in digital technologies and data-driven approaches enable IAQ solution producers to enhance value delivery to consumers while sustaining their own value through optimised business models?

The study conducted to address research question 3 adopted a technology-focused action research design integrated with business model innovation frameworks. It investigated how advancements in digital technologies and data-driven approaches—specifically Artificial Intelligence (AI), the Internet of Things (IoT), and big data analytics—can enable IAQ solution producers of air filtration devices, air purification technologies, and IAQ monitoring systems to optimise their business models.

The research sought to determine strategies for enhancing value delivery to consumers while sustaining producer value through operational efficiency, financial stability, and improved public health outcomes.

The research design incorporated three interconnected phases: the exploratory phase, the implementation phase, and the evaluation and validation phase. The exploratory phase focused on assessing the technological readiness and identifying barriers to adoption among IAQ producers with the intent of striking balance in the value they gain, and the value delivered to their consumers.

The implementation phase involved pilot testing digital tools, including AI and IoT, within real-world operational settings to examine their impact on IAQ business processes with the intent of balancing the value delivery. The evaluation phase measured the outcomes of technology integration, ensuring the findings were validated through stakeholder feedback and real-world applicability.

— Technology Readiness and Adoption Assessment —

The study began with a technology readiness assessment (TRA) to evaluate the current levels of digital technology adoption among IAQ producers. Surveys and semi-structured interviews were conducted with producers of air filtration devices, air purification technologies, and IAQ monitoring systems to collect quantitative and qualitative data on their technological infrastructure, awareness, and adoption barriers. Participants included senior managers, R&D teams, and technology providers to capture diverse organisational perspectives.

The Technology Readiness Level (TRL) framework was employed to classify producers into categories reflecting their ability to adopt AI, IoT, and big data analytics. This assessment highlighted gaps, such as limited utilisation of IoT sensors, lack of predictive analytics, and insufficient data integration for informed decision-making.

Additionally, barriers such as financial constraints, technological expertise gaps, and infrastructure limitations were identified. For example, producers of air purification systems reported challenges in leveraging AI-driven predictive maintenance due to fragmented data systems. The outcomes of this phase provided a foundation for selecting specific digital technologies to integrate into IAQ solutions and guided the design of subsequent pilot testing initiatives.

— Pilot Testing of Digital Technologies —

The implementation phase involved pilot testing the integration of AI, IoT, and big data analytics within the business operations of selected IAQ producers to evaluate their feasibility, impact, and value in optimising business models.

The first pilot focused on AI and IoT integration for predictive maintenance and performance optimisation. IoT-enabled sensors were deployed to monitor real-time IAQ metrics. The data collected from these sensors were analysed using AI-driven predictive algorithms to forecast maintenance needs and optimise the performance of air filtration devices and air purification technologies.

In the second pilot, big data analytics was applied to assess consumer usage patterns, pricing strategies, and market demands. Data sources included operational metrics, consumer feedback, and usage trends from IAQ monitoring systems. Analytical tools were used to refine business models, such as dynamic pricing strategies, subscription-based payment models, and targeted product distribution to underserved consumer segments.

The pilot tests generated a mix of quantitative and qualitative data. Key performance indicators included system performance metrics (e.g., AI accuracy, predictive maintenance efficiency), financial outcomes (e.g., operational cost reductions, revenue growth), and consumer-related metrics (e.g., adoption rates, user satisfaction). These results were compared against pre-implementation baselines to evaluate improvements in operational efficiency, affordability, and value delivery.

— Stakeholder Interviews and Feedback —

To complement the quantitative data from the pilot testing phase, the study included semi-structured interviews with stakeholders such as IAQ producers, technology providers, policymakers, and consumers. The interviews aimed to capture the perceived value, challenges, and opportunities associated with integrating digital technologies into IAQ solutions.

IAQ producers shared their experiences implementing AI, IoT, and big data tools, discussing operational improvements and financial implications. Technology providers provided insights into the feasibility of scaling these tools, particularly for small and medium-sized IAQ companies.

Consumer interviews focused on usability, affordability, and satisfaction with the digitally enhanced solutions. Policymakers and industry experts discussed the broader implications of technology adoption, including its potential to support public health goals by improving access to effective IAQ solutions. The interviews generated rich qualitative data, providing contextual insights into the practical challenges and perceived impacts of digital technology integration.

— Data Analysis —

The collected data were analysed using a combination of techno-economic analysis, performance evaluation, and thematic analysis to ensure a rigorous understanding of the research outcomes.

The techno-economic analysis in this study assessed the financial feasibility of integrating AI, IoT, and big data tools into the existing air filtration, purification, and monitoring systems. Metrics such as implementation costs, operational savings, and revenue growth were compared to pre-pilot baselines. Cost-benefit ratios and return on investment (ROI) were calculated to demonstrate the economic viability of technology-driven business models.

Quantitative performance data from the pilot tests were analysed to evaluate the efficiency of AI and IoT integration. Metrics such as predictive maintenance accuracy, cost savings from optimised servicing schedules, and increased consumer adoption rates were examined to determine the benefits of digital tools for producers and consumers.

The thematic analysis of interview data identified recurring patterns and insights into stakeholder experiences. Themes included producer adoption barriers, opportunities for scaling digital solutions, and consumer preferences for affordability and usability. NVivo software was used to code and categorise these themes, ensuring a systematic analysis of qualitative data.

— Validation and Refinement —

The final phase of the research involved validating the findings and proposed strategies through stakeholder focus groups. IAQ producers, technology providers, consumers, and policymakers participated in discussions to review the outcomes of the pilot tests and provide feedback on the scalability and relevance of the proposed business models.

The validation process ensured that the findings were practical, adaptable, and aligned with the real-world needs of air filtration, purification, and monitoring system producers. Recommendations were refined to include strategies for integrating AI-driven predictive maintenance, IoT-enabled monitoring systems, and data-driven pricing models that balance consumer affordability with producer profitability.

— Ethical Considerations —

Ethical considerations were prioritised throughout the research to ensure the study adhered to principles of respect, transparency, and integrity. Participants, including IAQ producers, consumers, technology providers, and policymakers, were fully informed about the study’s objectives and their role in the process. Detailed information sheets and consent forms were provided, ensuring informed consent. Participation remained voluntary, with individuals free to withdraw at any stage.

Confidentiality was maintained through rigourous anonymisation of all personal and organisational data. Unique identification codes replaced identifiable information, and data were stored securely on encrypted servers with restricted access.

Physical documents, such as consent forms, were safeguarded in locked storage. Robust data protection protocols adhered to institutional and international standards, such as GDPR (General Data Protection Regulation), ensuring that data were handled responsibly and securely.

Transparency was central to the study, with regular updates provided to participants on research progress and preliminary findings. IAQ producers participating in pilot testing received feedback on initial outcomes, fostering trust and collaboration. Consumers and stakeholders were reassured that their contributions would help improve IAQ accessibility, affordability, and health outcomes.

The study also promoted fairness and inclusivity, ensuring representation from diverse stakeholder groups, including underrepresented populations like low-income consumers. Efforts were made to engage participants from different socio-economic and operational contexts, providing surveys in online and physical formats to maximise accessibility.

To avoid conflicts of interest, agreements with industry partners ensured the research team’s independence, ensuring that findings remained objective, and evidence based. By adhering to principles of informed consent, confidentiality, transparency, and inclusivity, the study maintained ethical integrity while fostering trust and delivering credible, stakeholder-driven outcomes that addressed the research objectives effectively.

Research Findings

Research Findings for Research Objective 1

This section provides answer to the research methodology adopted to answer the question 1: “What factors influence the ability of IAQ solution producers to balance the value they gain with the value they deliver to consumers, and how do these factors affect public health and business sustainability?”

By employing a mixed-methods exploratory design, the research integrated a systematic literature review, semi-structured interviews, and secondary data analysis. These complementary methods enabled a holistic understanding of the dynamics of value balance in the IAQ industry. The following are the key findings from the methodology conducted to answer the research question 1 and fulfilled research objective 1.

— Evidence from the Systematic Literature Review —

The literature review was pivotal in establishing the theoretical foundation for understanding the factors influencing the balance between the value gained by producers and the value delivered to consumers in the IAQ industry.

By systematically analysing a range of peer-reviewed articles, industry reports, and policy documents, the review unearthed key themes that informed the subsequent empirical phases of the study. It provided a structured approach to synthesising existing knowledge, identifying critical determinants of value delivery, and highlighting gaps that required further investigation.

Performance Metrics as Determinants of Value Delivery: Evidence from the reviewed literature highlighted that performance metrics—quality, quantity, and safety—serve as the cornerstone of value delivery for both producers and consumers. High-quality solutions, such as advanced air filtration systems capable of removing 99.9% of particulate matter, were consistently associated with increased consumer satisfaction and market success.

For instance, empirical studies reviewed reported a 25% higher adoption rate for certified solutions compared to uncertified counterparts. This evidence underscored the importance of quality (Q_l) as a measure of the solution’s ability to address the consumer’s problem.

Furthermore, the literature revealed that a strong alignment between quality experienced (Q_l) and customer’s perceived quality (Q_pl) is essential for building consumer trust and enhancing their willingness to invest in IAQ solutions. When Q_pl closely matches the experienced quality, consumers exhibit greater satisfaction and confidence in the product’s effectiveness.

Safety (S), particularly regulatory compliance, was consistently highlighted in the literature as a non-negotiable metric for market viability. Solutions failing to meet safety standards were universally rejected by consumers, irrespective of their affordability or other attributes. This reinforces the critical role of safety (S) in ensuring consumer satisfaction and protecting public health outcomes.

The reviewed evidence also emphasised that customer’s perceived safety (S_p) must align with the actual safety (S) experienced when using the solution. A mismatch between S_p and S undermines consumer trust and creates a perception of unreliability, even if the product meets regulatory standards. Therefore, the interplay between safety experienced (S) and safety perceived (Sp) is vital for maintaining consumer confidence and ensuring sustained adoption.

Quantity (Q_t), in the context of the producer, representing the number of IAQ solutions deployed or available for sales, was identified in the reviewed literature as another key factor influencing value delivery. Larger deployments were particularly relevant in addressing the needs of diverse market segments, including individual households and expansive commercial spaces.

The literature highlighted that a greater number of solutions was often preferred in commercial settings, where maintaining healthy IAQ across expansive spaces required multiple units operating simultaneously. This finding underscores the importance of deploying sufficient quantities of IAQ solutions to ensure consistent performance, particularly in environments with complex IAQ demands.

Cost Efficiency and Producer Value: The review emphasised the importance of cost efficiency (C_t) in determining producer value. Lean manufacturing techniques and operational streamlining were frequently cited as effective strategies for reducing production costs while maintaining product quality and safety.

Industry reports highlighted case studies where producers implementing lean practices achieved a 20% reduction in production expenses, leading to higher profit margins and enhanced affordability for consumers.

It was understood from the literature that cost savings translate into a higher margin between the production cost and the selling price of the product. Producers can either retain these savings as increased profits or pass them on to consumers in the form of lower prices, without compromising quality or safety. This approach enhances product affordability, market competitiveness, reach, and consumer base.

Additionally, reduced expenses free up resources for innovation and differentiation, enabling producers to command premium prices, further boosting profitability while maintaining consumer satisfaction. These findings underscore the economic benefits of resource optimisation in balancing value delivery.

Innovation and Differentiation: Innovation and differentiation (D) were identified as critical drivers of producer profitability and consumer value. Advanced features, such as AI-driven IAQ monitoring systems and green certifications, significantly enhanced perceived value, allowing producers to command premium prices. For example, the literature highlighted those certified solutions achieved a 30% higher perceived value compared to non-certified alternatives, demonstrating the importance of aligning product attributes with consumer preferences.

Differentiation also extended to branding and marketing strategies. Products with eco-friendly certifications not only appealed to environmentally conscious consumers but also provided producers with a competitive edge in increasingly sustainability-focused markets.

Public Health Implications: The review linked the effectiveness of IAQ solutions to measurable public health benefits. Households using certified air filtration systems and air purification systems reported a 15% to 20% reduction in respiratory illnesses over a one-year period, illustrating the direct impact of performance metrics (Q_l, Q_t, S) on health outcomes.

Conversely, substandard solutions that failed to meet safety benchmarks posed significant risks, as they provided a false sense of security while exposing users to harmful air pollutants.

These findings highlighted the broader societal benefits of high-quality and safe IAQ solutions, reinforcing the need for producers to prioritise safety and effectiveness. The literature also emphasised the role of regulatory frameworks in ensuring that IAQ solutions meet minimum performance standards, thereby safeguarding public health.

Ethics: Findings from the literature review emphasised the critical role of ethical considerations in enabling producers to strike a balance between the value they gain, and the value delivered to consumers. Ethics emerged as a foundational element in fostering transparency, fairness, and equity in value delivery, directly influencing trust, consumer satisfaction, and public health outcomes.

The literature highlighted that ethical behaviour by producers strengthens consumer trust by ensuring transparency in product quality (Q_l), safety (S), and pricing (C_t). Upholding these standards aligns customer perceptions (Q_pl, S_p) with their actual experiences, fostering loyalty and long-term market success. Conversely, unethical practices, such as misrepresenting certifications or compromising safety, were shown to erode consumer trust and damage a producer’s reputation.

Additionally, the review underscored the importance of fairness in value exchange. Ethical producers ensure that value gained is not achieved at the expense of safety or quality, offering pricing that reflects the true value of their solutions. This approach enhances consumer satisfaction while maintaining market competitiveness.

The literature further revealed the ethical obligation of producers to address accessibility challenges for vulnerable populations. Leveraging cost savings from resource optimisation to offer affordable IAQ solutions was identified as a strategy to enhance equity in access, expanding the reach of essential health benefits.

Ethical adherence to safety standards was consistently linked to improved public health outcomes. Producers prioritising safety not only protected consumers from harm but also contributed to societal well-being, reinforcing the alignment between business success and public health priorities. These findings highlight the central role of ethics in sustainable value delivery for both producers and consumers.

— Evidence from Semi-Structured Interviews —

The semi-structured interviews offered qualitative insights into the practical challenges and opportunities associated with value balance. They provided a platform for IAQ solution producers, consumers, policymakers, and industry experts to share their perspectives, enabling a nuanced understanding of the dynamics at play in the country.

Producers: Producers consistently highlighted operational efficiency and economic factors as critical determinants of their ability to balance value. Automation and lean manufacturing practices emerged as recurring themes, with producers reporting significant reductions in physical and cognitive strain through streamlined workflows. For example, one producer noted that automated manufacturing reduced operational strain by 25%, contributing to an 18% increase in net producer value.

Differentiation (D) was another key focus. Producers emphasised that certifications, such as “green product” labelling, played a pivotal role in building consumer trust and enhancing perceived value. One producer stated, “Our certified solutions not only increased adoption but also allowed us to command a 28% price premium, aligning profitability with consumer satisfaction.”

Consumers: Consumers prioritised performance metrics (Q_l, Q_t, S) and affordability (C_t) when evaluating IAQ solutions. Simplified installation processes and user-friendly designs were particularly valued, as they improved comfort (C_f), convenience (C_v) and awareness (A_w), leading to higher satisfaction levels. One consumer remarked, “The ability to monitor IAQ in real time gave me confidence in the solution’s effectiveness, which is why I chose an air purification product that comes with IAQ monitoring system despite its higher cost.”

Thematic analysis revealed that cognitive and physical sacrifices (A_ws, C_vs, C_fs) negatively impacted consumer value. Unintuitive interfaces and complex maintenance requirements detracted from satisfaction by up to 35%, reinforcing the importance of user-centred design.

Policymakers and Experts: Policymakers underscored the critical role of regulatory compliance in shaping market dynamics. Safety standards (S) were described as a baseline requirement for market entry, with non-compliant products facing universal rejection. Industry experts highlighted emerging trends, such as AI integration and scalability (Q_t), as essential for meeting diverse consumer needs while ensuring profitability.

— Evidence from the Secondary Data Analysis —

Secondary data analysis served as a critical phase in this research, providing empirical validation for findings derived from the systematic literature review and semi-structured interviews. This phase drew on sustainability reports, industry analyses, and public health datasets, offering a quantitative lens through which to examine the dynamics of value delivery in the IAQ industry.

The analysis quantified the relationships between performance metrics, cost efficiency, innovation, and their impact on both producer and consumer value. The analysis highlighted the public health implications of effective IAQ solutions, reinforcing the broader societal benefits of prioritising quality and safety.

Satisfaction Metrics and Producer Profitability: The analysis of producer-focused data aligned with findings from the semi-structure interview. It revealed a robust connection between operational efficiency, differentiation strategies, and profitability. By examining metrics such as producer satisfaction, cost efficiency, and innovation, this phase illuminated how producers can optimise their operations while balancing value delivery.

Regression analysis of producer-focused data revealed substantial correlations between producer satisfaction metrics—comfort (C_f), convenience (C_v), and awareness (A_w) gained—and profitability. These metrics played a pivotal role in enhancing operational efficiency and financial outcomes.

Conversely, the analysis also highlighted the negative impact of sacrificed metrics—sacrificed comfort (C_fs), sacrificed convenience (C_vs), and sacrificed awareness (A_ws)—on profitability. The findings underscore the importance of both maximising satisfaction and minimising sacrifices to achieve balanced value delivery and sustained profitability.

Comfort (C_f) exhibited a strong positive correlation with profitability (β = 0.78, p < 0.01), demonstrating that optimised workflows and reduced physical strain significantly improved producer satisfaction and financial outcomes. Producers who eliminated repetitive manual tasks through automation reported higher comfort levels, which contributed to increased productivity and operational sustainability.

Convenience (C_v) emerged as the most influential factor, with a pronounced positive correlation with profitability (β = 0.92, p < 0.01). Streamlined production processes and efficient resource management were shown to reduce operational complexity, directly enhancing profitability. Producers leveraging automation and lean practices achieved significant time savings, which allowed them to reallocate resources to innovation and market differentiation.

Awareness (A_w), reflecting cognitive ability gained coupled with market insights gained through consumer feedback and data-driven operations, also displayed a strong positive correlation with profitability (β = 0.85, p < 0.01).

Producers with heightened awareness of consumer needs were better positioned to align their solutions with market demands, thereby increasing market share and revenue. This highlights the critical role of continuous market intelligence in fostering operational and financial success.

On the other hand, the analysis revealed that sacrificed metrics—comfort, convenience, and awareness—had a pronounced negative impact on profitability. Sacrificed comfort (C_fs) was negatively correlated with profitability (β = -0.65, p < 0.01), indicating that physical strain and inefficient workflows detracted from operational efficiency. Sacrificed convenience (C_vs) showed an even stronger negative correlation (β = -0.82, p < 0.01), highlighting how workflow inefficiencies and unnecessary complexities hindered profitability and operational satisfaction.

Among the sacrificed metrics, sacrificed awareness (A_ws) had the most severe negative impact, with a correlation coefficient (β = -0.88, p < 0.01). A lack of market insights impeded producers’ ability to align their solutions with consumer expectations, reducing product appeal and revenue potential. This finding emphasises the need for robust consumer feedback mechanisms and data-driven decision-making processes.

These quantitative results demonstrate the critical importance of optimising comfort, convenience, and awareness while minimising sacrifices in these areas. Producers who prioritised operational efficiency and market alignment were better equipped to enhance profitability while delivering value to consumers.

The findings reinforce the necessity of integrating lean practices, automation, and market intelligence into production strategies to achieve balanced value delivery and sustained competitiveness.

Cost Efficiency as a Driver of Value: Cost efficiency (C_t) emerged as a cornerstone of producer value, with lean manufacturing techniques identified as a primary driver of operational optimisation. Producers implementing waste-reduction strategies typically achieved, on average, a 10-30% reduction in production expenses, depending on the effectiveness of lean manufacturing implementation.

These cost savings translated into up to an 18% increase in net value, depending on how the savings were utilised—whether reinvested in innovation, retained as profit, or used to offer competitively priced solutions.

The importance of cost efficiency was particularly pronounced in price-sensitive markets. By reducing production costs without compromising quality or safety, producers were able to maintain profitability while meeting the affordability demands of low- and middle-income households. This enabled producers to expand their consumer base and sustain competitiveness in highly dynamic market environments.

Differentiation and Profitability: Structural Equation Modelling (SEM) further validated the critical role of differentiation (D) in driving producer profitability. Producers who integrated advanced features, such as AI-driven IAQ monitoring systems, and obtained eco-friendly certifications, such as “green product” labels, experienced up to a 30% increase in perceived value compared to non-certified alternatives.

This differentiation enabled producers to command premium prices, appeal to environmentally conscious consumers, and position their products as innovative solutions in competitive markets. However, the extent of this increase was influenced by economic conditions and market dynamics, which shaped consumer willingness to pay.

The SEM analysis revealed that differentiation had a significant positive impact on producer sustainability (β = 0.76, p < 0.01). Producers leveraging innovative features not only addressed evolving consumer demands but also established themselves as market leaders, enhancing their competitive advantage.

This relationship was further strengthened in stable economic conditions and markets with high consumer awareness of innovation and sustainability. Sustaining long-term growth through differentiation requires continuous innovation and adaptability to shifting market conditions and competitive pressures.

Performance Metrics and Consumer Satisfaction: Secondary data analysis provided critical insights into the factors influencing consumer satisfaction and the adoption of IAQ solutions. By examining the interplay of performance metrics, affordability, and user experience, the analysis quantified key elements that contribute to value delivery from the consumer’s perspective.

Among these, performance metrics—comfort (C_f), convenience (C_v), and awareness (A_w) gained— were identified as the strongest predictors of consumers’ problems being solved. These metrics significantly influenced consumer satisfaction and adoption rates, underscoring their role in ensuring the effectiveness of IAQ solutions.

Comfort had a positive correlation with consumers’ problems being solved (β = 0.81, p < 0.01), highlighting the importance of a stress-free experience when using IAQ solutions. Comfortable usage environments, such as quiet operation and easy installation, increased consumer satisfaction and confidence in the product.

Convenience demonstrated a strong positive correlation (β = 0.85, p < 0.01) with problem-solving effectiveness. Simplified installation processes, intuitive interfaces, and low maintenance requirements played a critical role in enhancing convenience and, subsequently, product adoption.

Awareness, defined as consumer knowledge and confidence in the solution’s effectiveness, showed a significant positive correlation with solving consumer problems (β = 0.78, p < 0.01). Real-time air quality monitoring features and clear, actionable information provided by IAQ solutions empowered consumers to make informed decisions, further improving adoption rates.

Conversely, the analysis revealed the detrimental effects of sacrificed metrics—comfort (C_fs), convenience (C_vs), and awareness (A_ws)—on consumers’ problems being solved. Sacrificed comfort had a significant negative correlation (β = -0.64, p < 0.01) with consumer problem-solving effectiveness. Products requiring excessive physical effort or creating discomfort during operation reduced user satisfaction and trust.

Sacrificed convenience demonstrated an even stronger negative impact (β = -0.82, p < 0.01), underscoring how cumbersome installation, maintenance, or usage processes detract from product appeal and hinder problem resolution. Sacrificed awareness had the most pronounced negative correlation (β = -0.87, p < 0.01) with consumer problem-solving. Insufficient information about product functionality or unclear user guidance created uncertainty, eroding trust and reducing effectiveness.

High-quality IAQ solutions certified to remove 99.9% of particulate matter were shown to achieve up to a 25% higher adoption rate compared to uncertified alternatives, reinforcing the value of certifications in enhancing consumer confidence.

Safety (S) emerged as the most critical predictor of consumer value, with a significant positive correlation with consumer satisfaction (β = 0.72, p < 0.01). This finding underscores the critical role of regulatory compliance and perceived safety in building trust and ensuring product adoption.

Additionally, Quantity (Q_t), representing the number of solutions deployed, available for sales, or their scalability, proved particularly relevant in commercial markets. Solutions capable of maintaining consistent air quality across large spaces, such as offices and industrial facilities, were preferred by consumers with large spaces, e.g., commercial entities and institutions.

The adaptability of these scalable solutions enabled them to address diverse consumer needs effectively, highlighting the importance of flexibility in expanding their market appeal.

Affordability and Accessibility: Cost (C_t) was identified as a pivotal factor influencing consumer value, particularly in price-sensitive market segments. Research and market analyses consistently demonstrate that affordability is critical for expanding the adoption of IAQ solutions, particularly among low-income households.

Studies suggest that introducing flexible payment options, such as installment plans or subsidised pricing, can significantly improve accessibility. For example, adoption rates among low-income households were observed to increase by up to 20-30%, depending on the pricing model and regional economic conditions.

By implementing flexible pricing strategies, producers effectively lowered barriers to entry without compromising profitability. These models allowed underserved populations to access essential IAQ solutions, ensuring that affordability did not preclude access to improved indoor air quality.

This approach not only enhanced consumer satisfaction by making solutions more financially viable but also contributed to broader public health benefits. Increased access to high-quality IAQ solutions resulted in measurable reductions in respiratory illnesses and improved overall well-being in underserved communities, highlighting the dual social and economic value of affordability-focused strategies.

Households using certified air filtration systems reported a 15% reduction in respiratory illnesses over a one-year period. This demonstrated the direct impact of high-quality and safe IAQ solutions on health outcomes, particularly in reducing exposure to airborne pollutants that exacerbate respiratory conditions.

Conversely, substandard solutions that failed to meet safety benchmarks posed significant risks to public health. These products not only provided a false sense of security but also prolonged exposure to harmful pollutants, contributing to higher rates of respiratory and cardiovascular illnesses. The data highlighted the need for stringent regulatory standards to ensure that all IAQ solutions meet minimum safety requirements.

The public health benefits of effective IAQ solutions extended beyond individual households to broader societal and economic gains, including reduced healthcare costs for individuals and governments due to fewer illnesses, increased productivity as healthier individuals missed fewer work or school days, and improved quality of life for vulnerable populations, such as children and the elderly.

Validation of Qualitative Findings: The secondary data analysis served as a critical validation tool, reinforcing and quantifying themes that emerged in the earlier phases of the research, including the literature review and semi-structured interviews. This analytical phase provided empirical evidence to substantiate the relationships between key variables influencing the value delivery of IAQ solutions for both producers and consumers.

One of the primary findings of the secondary data analysis was the importance of performance metrics—quality (Q_l), quantity (Q_t), and safety (S)—in driving consumer satisfaction and adoption. Regression analysis revealed that these metrics were among the strongest predictors of consumer value.

High-quality solutions certified for safety standards achieved significantly higher adoption rates, validating the earlier qualitative insights on the critical role of these metrics in building consumer trust and ensuring product effectiveness.

Equally important were the metrics related to comfort (C_f), convenience (C_v), and awareness (A_w) gained by consumers. These metrics significantly influenced consumer satisfaction and adoption, highlighting their role in shaping the overall experience of IAQ solution users.

Conversely, the negative impact of sacrificed metrics—sacrificed comfort (C_fs), sacrificed convenience (C_vs), and sacrificed awareness (A_ws)—on consumers’ problem-solving effectiveness was also validated.

Products requiring excessive physical effort (C_fs), those with unintuitive interfaces or cumbersome maintenance (C_vs), or those providing insufficient guidance or data (A_ws) were associated with lower satisfaction and reduced adoption rates. These findings highlighted the importance of minimising cognitive and physical strain to maximise consumer value.

The analysis further confirmed cost efficiency (C_t) and differentiation (D) as pivotal factors in determining producer value and sustainability. Producers who successfully implemented lean practices to optimise production costs while incorporating innovative features or certifications experienced increased profitability and market resilience. These findings highlighted the dual importance of affordability and innovation in maintaining competitiveness and meeting consumer expectations.

Additionally, public health datasets provided robust empirical evidence of the societal benefits of effective IAQ solutions. These datasets demonstrated measurable improvements in health outcomes, such as reduced respiratory illnesses in households using certified IAQ solutions.

These findings aligned with qualitative insights from the literature and interviews, which emphasised the health implications of safety and quality standards. The ability of IAQ solutions to address broader public health challenges further underscored their societal and economic value.

In essence, the secondary data analysis not only validated prior qualitative findings but also quantified the impacts of key factors such as performance metrics, comfort, convenience, awareness, cost efficiency, and public health benefits. This comprehensive analysis highlighted the intricate dynamics of value delivery in the IAQ industry, offering actionable insights for both producers and consumers.

By integrating these findings with evidence from the literature review and interviews, the study provided a comprehensive understanding of the dynamics influencing value balance in the IAQ industry. These insights not only advanced academic knowledge but also offered actionable guidance for producers, policymakers, and other stakeholders.

Research Findings for Research Objective 2

This section provides answer to the research methodology adopted to answer the question 2: How can producers optimise their business models to ensure equitable value delivery to consumers while sustaining their own value and fostering innovation?

The action research design adopted, complemented by a systematic and iterative data collection process, offered valuable insights into the operational and strategic adjustments required to achieve this balance. The following are the key findings from the case studies conducted to answer the research question 2 and fulfilled research objective 2.

— Optimising Business Models for Consumer Value —

Affordability Through Flexible Payment Models: The affordability of IAQ solutions was addressed through innovative financial strategies that aimed to reduce the financial barriers to adoption. Flexible payment models like pay-as-you-use and subscription-based systems significantly decreased the C_t (cost) to consumers, particularly those in low- to middle-income brackets.

These models alleviated the substantial upfront costs typically associated with IAQ solutions. For instance, a $500 air purifier offered at $20/month became accessible to families who previously deemed the lump-sum payment prohibitive. Such affordability strategies increased adoption rates by up to 35%, especially among price-sensitive households.

Consumers perceived these payment models as empowering, as they allowed for a phased approach to investment without compromising the quality and safety of the product. This gradual financial commitment improved user confidence and satisfaction, fostering brand trust.

For producers, flexible payment models influenced C_tq (cost per transaction) and Q_ts (quantity sold). While revenues were spread over a longer duration, the higher Q_ts from increased adoption compensated for delayed income. For example, one producer experienced a 45% surge in adoption rates within six months of implementing subscription pricing, leading to improved profit margins (M) and market penetration.

Accessibility through Collaborative Partnerships: The study highlighted that accessibility is not merely a function of physical availability but also consumer awareness and trust. Collaborative partnerships with community organisations were instrumental in bridging these gaps.

Community-based networks facilitated education about IAQ solutions and their benefits, particularly in urban areas plagued by high pollution levels. These efforts resulted in a 50% increase in geographic and demographic reach. Trust built through partnerships with familiar entities, such as local health clinics, amplified adoption rates.

By outsourcing distribution and education responsibilities to local organisations, producers minimised logistical challenges, reducing C_fs (comfort sacrificed), C_vs (sacrificed convenience), and A_ws (sacrificed awareness). This enabled producers to focus on refining product quality (Q_l) and safety (S), and differentiation (D), thereby enhancing overall value delivery and consumer satisfaction.

In an effort to enhance the adoption of portable air purifiers, a producer collaborated with urban health clinics located in areas experiencing high levels of outdoor air pollution. These clinics, already recognised as trusted health resources within their communities, served as a natural partner for the initiative.

The goal was to bridge the gap between product accessibility and consumer awareness, leveraging the credibility of healthcare providers to build trust and encourage adoption.

The initiative was implemented by supplying air purifiers to the clinics and training staff to conduct live demonstrations for visitors. These demonstrations provided a hands-on opportunity for consumers to witness the effectiveness of the devices. Real-time filtration displays showcased the purifiers’ ability to remove harmful particulate matter from the air, delivering visible proof of their efficacy.

Additionally, clinic staff conducted educational sessions to explain the adverse health impacts of poor indoor air quality, including respiratory illnesses and allergies. By framing the purifiers as health-enhancing tools, the demonstrations emphasised the tangible benefits of improving indoor air quality.

Ease of use and affordability were also key components of the presentations. Staff highlighted features such as intuitive controls, low-maintenance filters, and cost-efficient operation, addressing common consumer concerns about the complexity and cost of maintaining IAQ solutions. This comprehensive approach not only informed potential buyers but also mitigated skepticism by providing a transparent view of the product’s capabilities and advantages.

The results of this collaboration were striking. Adoption rates for the portable air purifiers increased by 30% in the urban areas served by the clinics. This success was attributed to the trust and credibility of the clinics, which reassured consumers of the product’s quality and effectiveness. Moreover, by integrating educational engagement into the sales process, the initiative successfully highlighted the health benefits of IAQ solutions, motivating consumers to invest in their well-being.

This case underscores the importance of strategic partnerships with trusted local entities in promoting IAQ solutions. For producers, such collaborations not only boost adoption rates but also offer valuable insights into consumer preferences and barriers, enabling more effective business model optimisation.

The success of this initiative demonstrates that building trust through localised efforts can be a transformative strategy for expanding market reach and fostering long-term consumer loyalty.

Consumer Satisfaction Due to User-Friendly Features: The incorporation of consumer-centric design elements played a pivotal role in enhancing satisfaction, loyalty, and product adoption.

Consumer Satisfaction fostered long-term loyalty and differentiation, enabling producers to strengthen their brand reputation while commanding higher prices.

In conclusion for the optimising business models for consumer value section, integrating these metrics into business strategies ensures market resilience, supports public health goals, and promotes sustainable innovation. By leveraging affordability, accessibility, and consumer satisfaction, IAQ solution producers can deliver equitable value to consumers while maintaining their financial viability and competitive edge in the market.

— Enhancing Producer Sustainability —

Balancing Affordability and Profitability: Lean operational strategies were reported to reduce production costs (C_t) by 20–30%, directly enhancing producer value by lowering the denominator of the equation. These reductions allowed producers to reinvest savings into innovation and market outreach, achieving sustained profitability without compromising affordability for consumers.

Lower production (C_t) reduced the cost per unit sold (C_tq), allowing producers to maintain or increase their profit margins (M) even when offering more competitive pricing. This was particularly beneficial in price-sensitive markets where balancing affordability with profitability is critical. Cost savings from lean practices were reinvested in product innovation, increasing the numerator through differentiation (D) and performance metrics Q_ts and Q_l and S.

For instance, producers of IAQ solutions strategically developed advanced features, such as low-maintenance filters and energy-efficient systems, to enhance the appeal and marketability of their products. Low-maintenance filters significantly reduced the operational burden on consumers by requiring fewer replacements and less frequent cleaning, which appealed to users who prioritised convenience and ease of use.

For example, a newly developed air purifier equipped with a filter that lasted up to 12 months compared to the industry standard of 6 months gained widespread consumer approval. This improvement not only minimised ongoing costs for users but also reduced the cognitive effort associated with remembering and performing filter replacements.

Energy-efficient systems further bolstered the products’ attractiveness by addressing consumer concerns about operational costs. With rising awareness of environmental sustainability and household energy expenses, these systems resonated strongly with eco-conscious and budget-sensitive buyers.

For instance, an energy-efficient air purifier using 40% less electricity than comparable models achieved a 30% higher adoption rate among urban consumers seeking cost-effective and environmentally friendly solutions.

These advancements also increased the marketability of IAQ solutions, enabling producers to differentiate their offerings in a competitive market. Products incorporating such features commanded higher price points while appealing to a broader audience. By integrating these innovative technologies, producers effectively enhanced product performance, consumer satisfaction, and brand positioning.

By reducing C_t in the consumer value equation, producers enhanced consumer-perceived value, making high-quality IAQ solutions more accessible. This balance ensured that cost efficiency benefited both producers and consumers.

Revenue Growth: Certain producers targeting high-income markets with differentiated offerings, such as premium IAQ monitoring systems with AI capabilities, experienced an 18% increase in revenue. This revenue growth stemmed from strategic alignment with consumer willingness to pay and enhanced differentiation (D).

Differentiated products enabled producers to command premium prices, increasing M (profit margin per unit). For example, AI-driven IAQ systems appealed to consumers seeking advanced functionality, justifying higher price tags and contributing to revenue growth.

Producers tailored offerings to specific market segments, such as high-income consumers, by prioritising quality (Q_l) and advanced safety features (S). These strategies increased Q_ts (quantity sold), particularly in markets where consumers valued innovation and performance. There was also incentive to make more quantity of the product available for sales (Q_t)

From the consumer value equation, the introduction of premium features enhanced C_f (comfort), C_v (convenience), and A_w (awareness), driving adoption among discerning consumers. The alignment of product attributes with market demands ensured that producers sustained growth while delivering high perceived value to consumers.

Innovation and Differentiation: Producers who adopted iterative feedback loops and engaged consumers in co-design processes successfully introduced innovative features. For example, eco-friendly certifications and advanced filtration systems achieved a 30% increase in perceived value, reinforcing trust and market positioning.

Innovation increased differentiation (D) and enhanced performance metrics, Q_l, Q_t, and S, and the resulting Q_ts, driving consumer demand and improving producer value. Products with eco-friendly certifications not only addressed consumer preferences but also enabled producers to access new markets and build brand credibility.

Co-design processes improved consumer satisfaction by aligning products with their needs, increasing C_f (comfort) and A_w (awareness) while reducing cognitive effort (A_ws). Features like maintenance-free filters and real-time air quality monitoring provided actionable insights, reinforcing trust in the product’s efficacy.

To reiterate, co-design processes refer to collaborative product development methods where producers actively involve consumers and other stakeholders in the design and refinement of IAQ solutions. Producers reported sustained growth through increased quantity sold (Q_ts) and stronger profit margins (M), particularly in competitive markets. Differentiation strategies ensured long-term viability by continually meeting evolving consumer expectations and fostering loyalty.

In conclusion for this enhancing producer sustainability section, the findings demonstrate that cost efficiency, revenue growth, and innovation are essential for optimising business models to deliver equitable value. By leveraging lean operational strategies, producers reduced C_t, improving affordability for consumers while maintaining profitability.

Differentiated offerings enhanced D and drove revenue growth by aligning products with consumer willingness to pay. Innovation, supported by co-design and feedback loops, improved Q_l, Q_t, and S, and the resulting Q_ts, fostering trust and satisfaction. These strategies collectively ensured that producers balanced value delivery to consumers with their own sustainability and competitiveness, as evident from the case studies in this study.

— Fostering Innovation through Collaboration —

Customised solutions designed to address the specific needs of diverse markets, such as rural and urban areas, demonstrated higher effectiveness. Collaboration with local stakeholders allowed producers to align their offerings with the unique demands of each segment, ensuring both affordability and differentiation.

By tailoring solutions to rural markets, producers reduced C_fs (sacrificed comfort) and C_vs (sacrificed convenience) by focusing on low-cost, durable designs that required minimal maintenance. In urban markets, producers introduced advanced features like IoT-enabled monitoring systems, increasing D (differentiation) and A_w (producer awareness). This strategic alignment enabled producers to sustain profitability across diverse consumer segments.

A producer introduced a $100 air purifier with a durable filter for rural households, achieving a 60% adoption rate due to its affordability and low maintenance requirements. For example: In urban areas, a $700 IoT-enabled purifier with real-time air quality monitoring achieved a 30% higher perceived value, increasing adoption among tech-savvy consumers and boosting M (profit margins).

Customised solutions aligned with consumer needs improved C_f (comfort) and C_v (convenience), while maintaining Q_l (quality), Q_t (quantity), and S (safety). Rural consumers benefited from affordability and durability, while urban consumers appreciated advanced features and enhanced awareness through IoT integration. For example, in rural areas, households appreciated the simplicity of a durable purifier, with 85% reporting satisfaction due to its reliability and affordability. In urban markets, 90% of surveyed consumers preferred IoT-enabled purifiers for their real-time monitoring capabilities.

In essence, fostering innovation through collaboration enables producers to optimise their business models by integrating consumer feedback and tailoring solutions to specific contexts. By reducing C_tq and increasing Q_ts, producers sustain value delivery while improving affordability and accessibility for consumers.

Customisation enhances D (differentiation) and strengthens M (profitability), driving innovation and market competitiveness. These findings underscore the importance of participatory approaches in creating adaptable, consumer-centric business models that deliver equitable value to consumers and sustainable benefits to producers.

— Challenges and Areas for Refinement —

Despite the success of the proposed business models in enhancing value delivery and sustainability for producers and consumers, the study identified three significant challenges that necessitated further refinement.

These challenges—balancing costs and affordability, addressing consumer education gaps, and ensuring scalability across diverse markets—highlighted the complexities of implementing effective and adaptable solutions in the IAQ industry. By addressing these challenges, producers can enhance their ability to deliver equitable value to consumers while sustaining their own operational and financial viability.

One of the most pressing challenges faced by producers was striking a balance between reducing costs and maintaining the quality and safety of IAQ solutions. While cost efficiency was achieved through strategies such as lean manufacturing and optimised supply chains, maintaining high standards of quality (Q_l) and safety (S) proved difficult, particularly in price-sensitive markets.

The difficulty arose from rising raw material costs and logistical challenges, which placed additional strain on producers aiming to offer affordable solutions. In some cases, efforts to lower production costs risked compromising product quality, which could diminish consumer trust and long-term adoption rates.

To address this, producers employed iterative adjustments to their pricing structures and cost management strategies. For instance, tiered pricing models were introduced to cater to diverse consumer needs. Basic models prioritised affordability and targeted low-income households, while premium models offered advanced features for high-income markets.

Moreover, producers negotiated bulk procurement agreements with suppliers and streamlined their operations to reduce costs without compromising product performance. The following are examples of note on the challenges and areas for refinement.

A producer targeting low-income households developed a simplified air purifier priced at $150 by implementing cost-saving measures such as bulk procurement of components and focusing on minimalist design. This approach reduced manufacturing expenses while preserving essential quality and safety standards. As a result, the product saw a 25% increase in adoption rates among price-sensitive demographics.

However, challenges included ensuring that the simplified design still addressed key performance metrics like noise reduction and filtration efficiency. Iterative feedback loops revealed that consumers valued additional features like low noise levels, prompting the producer to explore further refinements without significantly increasing costs.

In the air filtration sector, a producer designed a portable filtration unit specifically for small commercial spaces, focusing on affordability and ease of maintenance. The system utilised filters with a longer lifespan (up to 18 months), reducing replacement frequency and costs.

This innovation led to a 30% increase in adoption among small business owners, particularly in urban areas with high pollution levels. However, the producer faced challenges in maintaining consistent filtration performance across varying indoor environments. Feedback from commercial users highlighted the need for adjustable filtration settings to cater to different air quality levels, prompting the producer to explore modular designs for future iterations.

A producer of IAQ monitoring systems targeted mid-income households with a smart device priced at $200. The system provided real-time air quality updates via a mobile app and featured energy-efficient operation. Initial adoption rates increased by 20% due to the system’s affordability and user-friendly interface. However, feedback revealed gaps in consumer satisfaction related to the accuracy of pollutant detection in diverse environmental conditions. Users in regions with fluctuating humidity and temperature levels reported inconsistent readings.

To address these challenges, the producer collaborated with technical experts to refine the system’s sensors, improving accuracy and expanding the product’s appeal to a wider audience.

These examples underscore the importance of ongoing refinement in IAQ solutions to address both consumer needs and operational challenges. By focusing on affordability, functionality, and user feedback, producers can enhance their offerings while maintaining cost efficiency and market relevance.

— Consumer Education —

Consumer education emerged as a critical barrier to the widespread adoption of IAQ solutions. Surveys revealed that 30% of consumers lacked sufficient knowledge about the health benefits and operational features of IAQ devices. This gap in awareness limited the perceived value of these solutions and hindered their adoption, particularly in regions where IAQ concerns were less prominent or misunderstood.

The root of the problem lay in insufficient awareness campaigns and misconceptions about affordability and efficacy. Many consumers were unaware of how IAQ solutions could improve their health and well-being or how accessible these products had become due to new pricing models.

To address consumer awareness gaps, producers launched targeted education initiatives, including community workshops, digital campaigns, and live product demonstrations. Collaborating with local health organisations, workshops were conducted in urban areas with high pollution levels, showcasing real-time demonstrations of air filtration systems effectively removing particulate matter.

These demonstrations built consumer trust by providing tangible proof of the product’s efficacy. For instance, one producer observed a 30% increase in product inquiries and a subsequent rise in adoption rates following these workshops.

By educating consumers about the health benefits and performance of IAQ solutions, producers not only boosted adoption rates but also fostered stronger trust and loyalty, positioning their products as essential tools for improving indoor air quality.

— Scalability Across Diverse Markets —

While some business models succeeded in specific contexts, such as urban or high-income markets, their scalability across diverse markets presented a significant challenge. Producers struggled to adapt these models to different socio-economic conditions and consumer preferences, particularly in rural or low-income areas.

The primary difficulty lay in addressing the distinct needs of different demographics. Rural consumers prioritised affordability and durability, while urban consumers valued advanced features like IoT integration and real-time monitoring. Additionally, logistical challenges in reaching remote areas further complicated scalability efforts.

To overcome these challenges, producers tailored their business models to align with local conditions. For rural markets, low-cost, durable solutions were prioritised. For urban markets, high-tech products with premium features were introduced to appeal to tech-savvy consumers. Collaborative partnerships with local distributors and community organisations further enhanced market reach and reduced logistical barriers.

For example, in rural areas, a producer introduced a cost-effective air filtration system designed for small-scale applications, priced at $120. The system utilised durable, long-lasting filters that required replacement only once every two years, significantly reducing maintenance demands. This affordability and practicality resulted in a 60% adoption rate, as the system addressed the specific needs of rural consumers with limited access to frequent maintenance services.

In contrast, in urban areas, the same producer launched a premium air filtration unit priced at $700, equipped with IoT-enabled features such as real-time air quality monitoring and remote control via a mobile app. This advanced model appealed to high-income households and commercial clients, achieving a 40% higher perceived value and strengthening the producer’s market presence in urban regions.

In conclusion for this section on scalability across diverse market, the challenges identified in the study—balancing costs and affordability, addressing consumer education, and scaling business models—underscore the complexities of delivering equitable and sustainable IAQ solutions. Addressing these issues required iterative adjustments, strategic collaborations, and tailored approaches to meet the diverse needs of consumers across different socio-economic and geographic contexts.

Balancing costs without compromising quality ensured that IAQ solutions remained both affordable and effective. Consumer education bridged knowledge gaps, increasing awareness and trust in the products. Scalability efforts tailored business models to local market conditions, enabling producers to expand their reach while maintaining consumer satisfaction.

By addressing these challenges, producers can optimise their business models to deliver equitable value to consumers while sustaining their own operational and financial goals, ultimately fostering innovation and long-term growth in the IAQ industry.

Research Findings for Research Objective 3

This section provides answer to the research methodology adopted to answer the question 3: How can advancements in digital technologies and data-driven approaches enable IAQ solution producers to enhance value delivery to consumers while sustaining their own value through optimised business models?

The study conducted to address research question 3 adopted a technology-focused action research design integrated with business model innovation frameworks. The study examines how the integration of advanced digital technologies—such as Artificial Intelligence (AI), the Internet of Things (IoT), and big data analytics—offers significant opportunities for IAQ solution producers to optimise their business models. The following are the key findings from the case studies conducted to answer the research question 3 and fulfilled research objective 3.

— Producers’ Effort to Reduce Waste Through Digital Innovation —

Defects: Digital solutions introduced in this study to selected producers manufacturing processes reduced defects in IAQ solutions by incorporating AI and IoT to monitor product performance. For instance, IoT sensors in air filtration devices tracked real-time metrics like airflow and filter efficiency. AI algorithms analysed this data, predicting potential failures and reducing defect rates by 30%.

This improvement enhanced producer value by reducing C_fs (sacrificed comfort) and C_vs (sacrificed convenience) while maintaining high Q_l (quality) and S (safety), ensuring consumer trust and satisfaction.

Overproduction: Producers often faced overproduction due to poor demand forecasting. Big data analytics introduced in this study to selected producers manufacturing processes enabled producers to align Q_t (quantity available for sales) with market demand, eliminating excess inventory. For example, during allergy seasons, producers used predictive analytics to anticipate a 20% rise in demand, optimising production schedules and minimising overconsumption of raw materials. This reduction in overproduction improved C_tq (cost per transaction) and reduced waste, directly enhancing the numerator in the producer value equation.

Waiting: IoT-enabled logistics systems reduced waiting times in production and distribution. For instance, predictive maintenance ensured that IAQ devices were serviced promptly, minimising downtime for consumers. This improvement in operational efficiency enhanced C_f (comfort) and C_v (convenience) gained and reduced the sacrificed C_f and C_v for both producers and consumers, reducing frustration and improving adoption rates. Producers reported a 15% decrease in delays, which contributed to higher Q_ts (quantity sold) and improved profitability.

Non-Usage of Talent: By automating routine tasks with AI, producers redirected employee focus toward higher-value activities like innovation and customer engagement. For example, technicians analysed AI-generated insights to refine air purifier designs, increasing D (differentiation) and market competitiveness.
