More and more local administrations develop their innovation capacities, through "public innovation labs" often based on design methods: co-design with citizens, immersions, experimentation, iterative prototyping and testing development processes, etc. This participatory session will question emerging practices in governance and in the definition of urban public policies, e.g.: -How to start a public innovation process by design? -How to set up a design innovation lab in your administration? -What's the added value of design for policy and public services innovation? -How does design affect your organisation? Lille Metropole and Helsinki, World Design Capitals, will lead this session.
