Stakeholders involved in social housing and social integration are numerous (governmental services, non-profit organizations, volunteers, local authorities, etc.). These multiple actors, with heterogeneous resources (coming partly from the government, partly from other institutions) have different areas of intervention, which does not always make actions effective, the ultimate goal being obviously to increase social utility or societal utility created. In order to both increase knowledge about housing and social integration, and improve coordination between stakeholders, the French government designed and made available to local actors a methodology for a shared territorial diagnosis, called "360° diagnosis". In this communication, we present two case studies corresponding to the deployment of this tool in two regions. We propose a critical analysis of the implementation of this tool, by focusing on its uses and effects, this next to its philosophy and its initial intentions.
