We created a detailed system map to visualise how ownership is produced, distributed, and transformed across the lifecycle of packaged food. The map identifies key stakeholder groups, from producers and retailers to consumers, community fridges, and policymakers, and locates them within four lifecycle stages: 1. Production & Packaging Design, 2. Retail & Distribution, 3. Consumption & Use, 4. Post-Use & Redistribution. We analysed their types of ownership influence (structural, individual, psychological), relative power, and how ownership is transferred, institutionalised, or challenged through systemic flows. We wanted to move beyond viewing ownership as an individual attitude, and instead reveal it as a systemic condition shaped by roles, rules, and relationships. By mapping how ownership flows and transforms between stakeholders, we could identify critical leverage points for design interventions. This approach helps surface the complexity of shared responsibility in FMCG systems, highlighting how interventions must align with existing power structures and enable collaborative forms of ownership to scale.
We created a stakeholder ecology map that positions the customer and household within a broader ecosystem of actors influencing food ownership practices. This included retailers (management, marketing, operations, storefront staff), waste management entities, government regulators, landlords, co-living residents, social enterprises, NGOs, and voluntary initiatives. We used concentric layers to illustrate proximity and relational influence on the customer’s experience of ownership. By visualising this ecology, we could see how retailers, policy-makers, local government, and alternative models all play roles in enabling or constraining shared responsibility. This approach supported a more holistic, systemic framing of our design challenge, emphasising that shifting ownership models requires cross-sector collaboration, not just consumer behaviour change.
To make sense of how these systems shape everyday behaviour, we applied Behaviour Setting Theory (Barker, 1968). This allowed us to map the physical, social, and normative environments in which food ownership behaviours emerge.
We detailed:
Rather than viewing ownership as a fixed or personal mindset, we revealed it as:
A distributed and dynamic process, negotiated through routines, roles, and shared settings, from store to kitchen to bin.
By mapping these behaviour settings, we surfaced how ownership becomes:
This approach revealed hidden constraints and overlooked opportunities for intervention, howing us where the system actively resists more collaborative, circular models of consumption.
Through our combined analysis, stakeholder mapping, system mapping, and behaviour setting theory, we uncovered a core insight:
The system is not neutral. It actively shapes what people buy, how they store food, when they share (or don’t), and how waste is normalised.
From promotional pricing structures to fridge design, from loyalty cards to pack sizes, we saw how design choices across the food retail system profoundly shape individual decisions, mindsets, and assumptions about ownership.
What often appears as “personal behaviour” is in fact the outcome of layered social norms, physical constraints, and institutional signals.
This shifted our design question from:
“How do we get people to waste less?”
to
“How might we redesign the system so that wasting less becomes easier, more natural, and even socially reinforced?”
This systems-first mindset informed our next steps: designing speculative futures and transition interventions that challenge current defaults and propose new infrastructures for food ownership and retail.
To move from analysis to intervention, we adopted the Transition Design framework (Irwin et al., 2015) to understand the historical, interconnected, and value-laden nature of the current food retail system. Transition Design emphasises that wicked problems, like food waste, overconsumption, and unsustainable retail practices, cannot be solved with isolated fixes. They require long-term, multi-level change grounded in societal values and systemic understanding.
Using Transition Design lenses, we explored how the current food system has become locked-in over time through:
These overlapping forces reinforce the existing system, making alternative models feel difficult, risky, or even unimaginable to mainstream actors.
We built a Wicked Problems Map to surface and connect the complex, interdependent drivers of overconsumption and waste in packaged food systems. This mapping exercise identified factors spanning social norms, retail incentives, packaging design, infrastructure constraints, and individual behaviours. By visualising these interrelations, we made visible the complexity and entanglement of the problem space. We wanted to expose the full complexity of the challenge, showing how factors like retail incentives, social norms, and infrastructure reinforce each other. This helped us avoid simplistic solutions and frame the problem as truly systemic.
We applied the Multi-Level Perspective (MLP) framework to analyse how ownership practices in food consumption have evolved over time across three levels: 1. Landscape (broad cultural and societal trends), 2. Regime (dominant systems and infrastructures), and 3. Niche (emerging innovations and alternatives). We created a timeline to track these shifts from the 1940s to today. We aimed to understand how ownership norms and systems evolved over time. By placing current practices in historical context, we could see why certain behaviours persist and identify moments when meaningful change became possible.
We used the Iceberg Model to structure our analysis across four levels: visible events and behaviours, underlying patterns, systemic structures, and mental models. This visual diagram traced how everyday practices like bulk buying, convenience shopping, and food hoarding are shaped by deeper infrastructural, cultural, and psychological drivers.. We wanted to look beneath everyday actions to find the patterns, structures, and mindsets driving them. This helped us identify deeper areas to target for lasting change.
Our MLP (Multi-Level Perspective) analysis revealed the nuclear family as a dominant model that has historically shaped mainstream food systems, driving packaging formats, retail design, and shopping behaviours optimised for predictable, centralised household coordination.
To better understand the real-world implications of this legacy, we mapped and compared grocery journeys in both nuclear family and co-living contexts. This allowed us to see how ownership norms and routines that work well in a family setting can break down in shared living arrangements, leading to frictions like territorial behaviour, spoilage, and waste.
Nuclear Family: Linear, Coordinated, and Habitual
The nuclear family’s grocery journey is structured around planned consumption and collective routines:
Co-living: Fragmented, Impulsive, and Isolated
In contrast, the co-living journey is marked by impulse, individual agency, and minimal coordination:
To ensure our systemic analysis was grounded in real behaviours, emotions, and frictions, we conducted ethnographic research with individuals living in shared flats and co-living environments across London.
While our system maps and behaviour settings offered a bird’s-eye view of structural barriers, this phase allowed us to zoom into the messiness of everyday life, where routines are improvised, fridges are shared, and ownership is constantly negotiated.
We conducted in-depth ethnographic interviews with residents of co-living flats to understand their real-world practices, frustrations, and adaptations around shared food ownership. Participants also provided photos of their shared fridges to document space constraints, storage habits, and maintenance norms. We wanted to ground our systemic analysis in lived experience. By speaking directly with people navigating shared kitchens and storage, we could capture rich, situated details that reveal how ownership practices are negotiated, avoided, or break down in daily life.
Across multiple interviews and kitchen walkthroughs, one object consistently emerged as a symbol of conflict, control, and compromise:
the fridge.
In co-living environments, the fridge becomes more than just a storage space, it becomes a territorial boundary, a power marker, and an emotional flashpoint.
To further explore how ownership is enacted and negotiated in everyday life, we conducted cultural probes focused specifically on the fridge in shared households.
This simple yet revealing method helped us visualise ownership in physical space, uncovering the silent rules and relational dynamics that shaped food interaction.
What We Found:
This probe reinforced our earlier conclusion: ownership in shared living is rarely discussed, but constantly acted out. And because domestic infrastructure (like fridges) doesn’t support fluid or collective ownership, tension and waste build up silently.
These insights helped us reframe the fridge as a critical site of intervention, not just in homes, but in the design of food retail systems themselves.
We aimed to move from raw interview data to structured insights that could inform design. By codifying themes across participants, we identified patterns of shared pain points and systemic barriers that interventions would need to address to make collaborative ownership viable.
We translated these coded themes into a detailed system map. This map visualises the interconnections between factors like storage limits, emotional burnout, retail overportioning, hygiene expectations, and accountability breakdowns. We highlighted feedback loops and leverage points within the co-living context. We wanted to understand not just what the problems are, but how they interrelate and reinforce one another. Mapping the system helped us see where small design interventions could disrupt negative cycles or enable positive change toward shared responsibility.
To create meaningful systemic change, Transition Design requires a clear image of the future we want to transition toward. This is not a utopia, but a “preferable future”, one that reflects emerging values, challenges current norms, and makes space for radically new imaginaries.
Drawing from Dunne & Raby’s Speculative Design approach, we developed a provocative, grounded vision of what a more collaborative, circular, and emotionally supportive food retail system might look like. This vision was not intended as a solution, but as a tool for discussion, critique, and directional decision-making.
We invited participants to answer four key prompts:
1. What isn’t working anymore and needs to transition “out”?
2. What should we keep?
3. What existing innovations and practices can disrupt business as usual and ignite the transition?
4. What “pieces of our future vision” are already here in the present?
We collected and analysed these responses to identify both barriers and enablers of transition. By posing these questions, we aimed to surface collective knowledge about what to abandon, what to preserve, and what to amplify.
After gathering responses to our prompts, we synthesised participants’ ideas into four thematic vision maps:
Society Vision – exploring cultural and social values around food equity, inclusion, and shared food culture.
Store Vision – imagining retail experiences that support behaviour change, portion-conscious shopping, and community redistribution.
Co-Living Flats Vision – addressing shared responsibility, social cohesion, financial practicality, and smart home solutions in communal living.
Retail Industry Vision – outlining system-level shifts in retail culture, predictive systems, and policy frameworks for waste reduction.
These maps organised diverse ideas, quotes, and suggestions into structured clusters, making it easier to see emerging themes and connections.
To move beyond analysis toward actionable change, we applied a Transition Design Pathway approach. We conducted signal scanning to identify and analyse existing solutions and emerging practices that address ownership, waste, packaging, sharing, and retail design. These included weak signals, promising innovations, and local experiments already disrupting the dominant system.
We ran a 1.5-hour co-design workshop with 12 participants to envision the future of retail in ways that address ownership and waste challenges in food systems. The session was designed to move from systemic analysis to creative, practical design:
Card Game (Context–Tension–Solution): Participants used prompt cards to explore systemic dynamics, uncover tensions, and frame design challenges.
Solution Concept Development: Groups co-created interventions to address these tensions, imagining new ways to enable more sustainable and equitable ownership.
Store Layout Design: Teams envisioned how their solution would come to life in a retail environment, designing customer flows, zones, and interactions that support new behaviours.
Packaging, Promotion, and Shelf Design: Participants detailed how packaging formats, in-store signage, and merchandising could reinforce and normalise these new practices.
We captured all outputs and synthesised them into Idea Cards, each with a clear description and thematic objective.
This Independent Research Project (IRP) was developed as part of the MA Service Design programme at the Royal College of Art, by Plu Phumchumphol[Me] in collaboration with Miran Jurisevic and Madeline Mai, under the guidance of tutor David Evan-Eveleigh.
The aim of the IRP is to apply service design methodologies within a complex real-world context, in this case, the UK food retail system, and to critically examine both their potential and their limitations. Through a transition design approach supported by speculative design, this project explores how food retail can evolve toward a more circular and collaborative future in response to rising co-living trends and growing food waste.
By navigating constraints such as industry inertia, territorial food behaviours, and systemic misalignments, the project interrogates how service designers can not only adapt methods to context but also stretch the boundaries of the discipline itself, advancing service design as a tool for long-term societal transition.
Globally, around one-third of all food produced is wasted, amounting to approximately 1.3 billion tonnes annually (FAO, 2013). This contributes not only to hunger and resource depletion, but also to nearly 8–10% of global greenhouse gas emissions (UNEP, 2021).
The world currently produces 1.5 to 2 times the amount of food needed to feed the global population (Better Meets Reality, 2022). Yet every year, over 1.3 billion tonnes of food goes to waste, contributing to nearly 10% of global greenhouse gas emissions (UNEP, 2021).
While household behaviour is often the focus of intervention, our research shows that the retail system itself is a major leverage point in driving overconsumption and waste.
The current structure encourages:
People in the UK still primarily cook and eat at home, and most of those ingredients are purchased through mainstream grocery retailers. This reinforces why the retail system plays such a critical role in shaping both what people buy and how much food gets wasted.
So while cooking remains rooted in the home, the rules of what’s available, affordable, and waste-prone are still being set by the retail system.
This project recognises that reducing waste isn’t just about changing consumer behaviour, it’s about redesigning the system that shapes it.
We then systematically mapped responses we captured earlier, using the insights to clarify what elements of the current system need to be phased out, what valuable practices and values should be retained, what disruptive opportunities already exist, and what early indicators of our desired future are already emerging. We then synthesised all this work into a cohesive Future Vision statement. This text integrates critique, aspiration, and practical possibilities into a shared, design-oriented vision for more collaborative, circular, and sustainable ownership models in food systems.
At first glance, the simplest solution to food waste in co-living environments might be to just reduce packaging sizes, offering smaller portions to match smaller households. But through our research, it became clear that this would only address the symptom, not the system.
Smaller packs can actually lead to higher packaging waste, increased per-unit costs, and greater strain on logistics and inventory systems, all of which retailers are hesitant to adopt. Moreover, this approach assumes that individuals are the primary unit of consumption, ignoring the social dynamics and emotional labour involved in shared spaces. Our ethnographic findings revealed that waste isn’t just caused by quantity, but by ambiguous ownership, lack of trust, poor redistribution mechanisms, and systemic incentives to over-purchase.
Simply reducing portion sizes does not make sharing easier, ownership clearer, or systems more equitable.
In a system optimised for volume and profit, small-pack solutions are quickly co-opted as premium products, rather than tools for circularity. Without rethinking the underlying structures of ownership, coordination, and shared stewardship, small packaging becomes a technical fix applied to a relational and systemic problem.
This project showed us that to meaningfully reduce waste and redesign food systems, we need more than smaller sizes, we need smarter systems.
