This book examines smoking-prevention networks in Switzerland, in order to assess the management and performance of networks delivering public services. First, it considers how network managers can be distinguished based on work-context-related factors, and analyses how the interaction of these factors leads to either active or non-active network management within collaborative policy delivery arrangements. It then empirically investigates the effects that network management and other network-level and project-level factors have on the policy output performance of these networks. Adopting a multi-method approach combining a qualitative comparative analysis, case studies and rich empirical data, the book will appeal to academics and students of public policy, public administration, and public management. It will also be of use to practitioners responsible for the design and the management of policy delivery networks.
