This case study illustrates how migrants in Sweden were involved in the development of a new online platform Mobilearn (Mobilearn, n.d.). In particular, it shows how migrants have shaped the design of a new digital tool in collaboration with service providers from a range of public agencies. The resulting digital tool, Mobilearn, provides a number of key services tailored to the needs of migrants and helps to make public services provided to migrants more efficient. It is therefore a case study of the co-creation of a core service. Mobilearn has received multiple awards and is now being disseminated in other countries.
