PlatVel is an innovation project with NTNU and the municipality of Trondheim as partners. PlatVel is about the implementation of digital platforms in the public sector. PlatVel will generate knowledge about how digital platforms can be implemented in municipality-based public services, and how they can support existing and new work processes. Platform models have been applied by large technology companies such as Google, Facebook and Apple. Their application to the public sector is not as mature and more research is needed to see how these digital platform models can support innovation and delivery of public services. "Municipality as platform" is a research field where there is little empirical research results available. There is a potential that this type of research can help us make better and more efficient public services. PlatVel aims to generate such data. PlatVel cooperates with large platform projects such as Helseplattformen.
