People use a plethora of services every day. Our society has been shifting from product to service oriented with the rise of the sharing economy. While product design and development processes have been put in order and acknowledged long ago, not much of the services have witnessed the same – especially public services. Hence, this thesis studies the intersection of service, urban and transition design within the public sector, set up to create a value mapping tool for strengthening co-creation in public services. Co-creation is hereby seen as an important method as, as citizens, we are obliged to pay taxes, which fund public services. If our chosen services fail, we can just stop paying, which is not the case for public services and this in return results with mostly negative connotations. Built on existing theories, this thesis’s research shows how to implement design, which is important for its both actionable and imaginative features, to facilitate co-creation in public services. It does so by integrating design principles in both the proposed co-creation model, as well as the value mapping tool and enabling derivation of specific actions (after co-creation). This way, both the government and the citizens not only see the value of the process and the tool but reawaken the partnership and a sense of trust between the two. Additionally, this makes it easier for any designer to approach the design of public services. The thesis has both theoretical and practical value. The proposed co-creation model and the value mapping tool work in synergy and are envisioned to be used together. With this orchestrated use, the tool does not only strengthen co-creation in public services but offers actionable points for future development. It helps identify citizen’s area of interest related to a specific problem by utilising transition design and the introduced the concept of spatial touchpoints and value statements. The end output are key action points left to public service managers to tackle later on – but in this case the journey might be more important than the destination.
