"An important contribution at the forefront of debates about the future of public policy and public services. The authors have assembled an impressive range of contributors and skilfully drawn together a narrative that convincingly integrates theory and practice" Janet Newman, The Open University "This accessible text on co-production is long overdue. It draws together academic, policy and practice insights to advance knowledge and thinking in relation to participatory policy making and research." Lisa Goodson, University of Birmingham "An excellent analysis of the policy process, why it doesn't work and how it can work. With a focus on design principles, it brings together a strong cast of contributors from the academic, policy and practice worlds to show what an intelligent approach to co-production really means. Essential reading." Marilyn Taylor, Institute for Voluntary Action Research and University of the West of England
