SISCODE is a three-year project aiming to understand the co-creation phenomenon that is flourishing in Europe (in fab labs, living labs, social innovations, smart cities, communities and regions) and to analyse the context and conditions that support its effective introduction, scalability and replication. Eventually this will help bridge the gap between the process of co-constructing policies and their implementation. Co-creation will be analysed in particular in the light of Responsible Research and Innovation and Science, technology and innovation policies.
