This Handbook provides a comprehensive and authoritative account of the movement towards co-production of public services and outcomes, a topic which has recently become one of the most intensely debated in public management and administration, both in practice and in the academic literature. It explores in depth the processes of co-commissioning, co-design, co-delivery and co-assessment as major approaches to co-production through citizen voice and citizen action and as key mechanisms in the co-creation of public value. The key debates in the field are fully explored in chapters from over 50 eminent authors in the field, who examine the roots of co-production in the social sciences, the growth of co-production in policy and practice, its implementation and management in the public domain, and its governance, including its negative aspects (the 'dark side' of co-production). A final section discusses different aspects of the future research agenda for co-production.
