In the field of social services, co-production has become a buzzword for a set of instruments and ways of working that are meant to produce better outcomes in terms of service quality and efficiency. We understand co-production as a notion that refers to exchange relationships that include several dimensions of interaction (e.g., dialogue, practical matters and cooperation); it can relate to individual service relationships at the microlevel, as well as to the links between organizations at the mesolevel of the welfare system (Brandsen and Pestoff, 2006).
