CASE STUDY

Co-Designing a Service Model That’s Transforming Lives

While working as a UX and service designer at the design consultancy TWN, I led a service design project for the Ministry of Social Affairs in Estonia. The goal was to rethink the existing social service system for people with psychological disorders and intellectual disabilities, ensuring they receive the support needed to integrate into the community on equal terms with others.

The project took place in the midst of a nationwide de-institutionalization process, shifting from institutional care models to community-based support systems. Our challenge was twofold:

  1. User Needs: The existing services were fragmented, making it difficult for users and their families to navigate and access the right support.

  2. Systemic Change: The transition required aligning multiple stakeholders—service users, providers, policymakers, and administrators—under a shared vision.

About

Industry: Social Services / Public Sector / Service Design

Client: Ministry of Social Affairs, Estonia

Project Scope: Nationwide service system redesign for people with psychological disorders and intellectual disabilities

Target Users: Service users, families, social workers, service providers, policymakers

Key goals

  • Develop a research-backed, human-centered service model: Establish a validated, user-driven foundation to guide policy and service implementation.

  • Bridge institutional and community-based care: Support the transition from institutional care models to recovery-oriented, community-based services.

  • Empower service users in the design process: Ensure that the voices of vulnerable groups were meaningfully included in decision-making.

  • Align diverse stakeholder needs: Balance the perspectives of policymakers, service providers, and users to create a feasible, scalable service model.

  • Optimize cost efficiency while improving service quality: Enable people to access better, more personalized support in their community within the same budget as institutional care.

My role

I was the project manager and design lead of a consultant service design team of 5 people. My task was to plan the project methodology and lead the design team that executed the project. I was also responsible for communicating with the customer and presenting the project results.

I was actively involved in all the steps of the project from initial research to feedback collection to the new service model. 

I was also leading a follow up project where the service model was iteratively improved based on the collected feedback and facilitated another round of co-creation workshops in the following year.

Impact

We successfully steered the project in a co-creation direction, ensuring that the voices of the vulnerable target group were central to the design process. By developing and applying custom design techniques, we empowered service users to contribute meaningfully to shaping the new model.

At the same time, we actively involved the project team from the ministry—who had no prior design experience—in human-centered design methods. This hands-on approach enriched their understanding of user needs and ensured that the piloting of the service model was carried out with a strong human-centered foundation. This shift was crucial in moving the system away from rigid, policy-driven structures toward a more user-focused approach.

Key Outcomes

  • Co-Creation & Capacity Building
    We involved policymakers, service providers, and end users in collaborative design workshops, equipping them with human-centered design tools and methods. This helped the ministry team—who had no prior design experience—gain a practical understanding of how to develop and sustain user-centric services.

  • Service Blueprint & Piloting Tools
    We handed over a structured service blueprint along with a set of practical tools to support the piloting of the new service model. These materials provided a clear framework for iteration and implementation.

  • Pilot Implementation & Iteration
    We instructed the first round of pilot participants through a series of workshops and implemented the initial round of improvements based on their feedback. In collaboration with the in-house team, we prepared the second round of piloting, ensuring they could continue the work independently.

  • Scaling & Policy Impact
    Since its inception, the new service model has been piloted in more than 30 municipalities and has undergone multiple iterations based on continuous feedback. Service providers reported improved efficiency and collaboration, while users experienced greater accessibility and support. These insights have directly informed policy development, with legislation for nationwide implementation currently in preparation for 2025.

By embedding human-centered design into the system, we not only improved the service experience for end users but also enabled long-term transformation within the institutions responsible for delivering care. Our approach demonstrated that by bringing stakeholders together in an iterative and inclusive process, systemic change is possible—not only at the service level but at the policy level as well.

Methods

We followed an iterative process of research, co-creation, and testing to ensure that the redesigned service model addressed the real needs of service users, caregivers, and stakeholders at every level of the system.

Understanding the System: Secondary Research

To lay the groundwork, we conducted in-depth secondary research, analyzing key documentation such as development plans, policy frameworks, and case studies from other countries. This helped us map existing services, stakeholder relationships, and known systemic issues.

💡 Key Insight: A fragmented service landscape and inconsistent policies led to gaps in care, prompting a need for a more cohesive, user-centered model.

Engaging Stakeholders: Interviews & Observations

Since the service system involved a wide range of users and providers, we conducted a two-phase field study:

  • 7 group interviews with 43 stakeholders (policy makers, service providers, service user organizations, healthcare and education professionals, and local municipalities) to uncover broad systemic challenges.

  • 38 in-depth interviews and 6 contextual observations with service users, caregivers, and frontline professionals to capture personal experiences and workflow inefficiencies.

💡 Key Insight: Many users struggled with entering the system due to complex processes, while service providers faced administrative burdens that limited direct care time. These insights shaped our approach to simplifying access and optimizing resource allocation.

Making Sense of the Data: Thematic Analysis

All interviews and observations were transcribed and analyzed using a custom framework based on WHO’s life quality domains and key stages of the user journey (from identifying a need to navigating and exiting the system). We used affinity diagramming to cluster findings into actionable opportunity areas.

💡 Key Insight: Users needed services that aligned with their daily lives, rather than forcing them into rigid institutional structures. This directly informed our new service model’s flexibility and personalization features.

Bringing Collected Data to Life: Personas & User Needs

To bridge research and design, we created 15 personas representing five key user subgroups based on psychological and support needs. Each persona was designed to be concise yet rich in context, capturing real pain points, aspirations, and barriers within the service system.

Additionally, we developed user need cards, categorizing needs by service journey stage and life quality domain. These artifacts provided a tangible way for stakeholders to empathize with users and prioritize solutions.

💡 Key Insight: The personas and need cards helped stakeholders move beyond abstract discussions, enabling them to see how policy changes directly affected real people. This shifted conversations toward practical solutions rather than theoretical debates.

Co-Creation Workshops: Designing the Future Service Model

We facilitated 10 co-creation workshops with over 50 participants, using personas and journey mapping to collaboratively redesign the service experience. Each team focused on a different user group, iteratively refining their journey maps to address unmet needs.

💡 Key Outcome: Stakeholders co-designed user journeys that reduced bureaucracy, enhanced local support networks, and empowered users to navigate services more independently.

Refining the Model: Iteration & Risk Assessment

The ideas generated in workshops were synthesized into several service model prototypes, which we presented in another round of co-creation and discussion workshops to refine feasibility and assess potential risks of the proposed models.

💡 Key Outcome: By involving stakeholders early, we secured buy-in for key structural changes, such as streamlining service entry points and introducing proactive support mechanisms.

Real-World Validation: Piloting & Feedback

To test the feasibility of the new model, we launched a one-year pilot across eight municipalities, providing redesigned services to 40 individuals with psychological special needs. Throughout the pilot, we held reflection sessions with service providers to monitor implementation challenges.

At the end of the pilot, we conducted another round of interviews and surveys to measure impact and collect feedback for refinement.

💡 Key Outcome: Users reported increased accessibility and satisfaction, while service providers noted improved efficiency and collaboration. Based on these findings, the model was iterated for broader rollout.

Conclusion

By grounding design decisions in deep user research, collaborative ideation, and real-world testing, we developed a service model that better supported people with psychological special needs. The structured, iterative approach ensured that every change was backed by user insights, leading to a more inclusive and sustainable system.
