Contemporary urban development is increasingly characterized by collaboration and co-production between ‘experts’ and the ‘public’ in urban planning processes. Recently, local planning actors have adopted digital participatory platforms (DPPs) which are specifically built for networked engagement and collaboration purposes. However, the knowledge on embedding DPPs in wider planning dialogues is still limited and scattered. The aim of this paper is to provide a better understanding of the organizational conditions for the successful adoption and implementation of such networked co-production. Through a set of semi-structured interviews with representatives from public agencies and platform companies, we have analysed how organizational conditions for networked co-production manifest themselves in seven cases of DPP implementation. The analysis shows that these conditions are co-constitutive and co-evolutive rather than concurrent or sequential, with strong links between the compatibility of public agencies, attitudes to co-production, organizational cultures and incentives for co-production. The results critically emphasize the need to adopt holistic approaches to networked co-production, allowing for extensive experimentation and ‘learning by doing’.
