Multifaceted social problems such as safety, social inclusion, poverty, mobility, rural development, city regeneration, or labour market integration require integrated approaches to steering. NPM-related fragmentation of policy and fragmentation of implementation lead to unsatisfactory public outcomes and a heightened experienced loss of control on the part of policy makers. Governments are therefore looking for new instruments to address the boundary-spanning nature of many social problems. In their quest for achieving valued social outcomes, they struggle with their new role, and the insufficiency of both markets and hierarchies. In this book, a product of the IPMN 2010 conference in Rotterdam, authors explore new organisational mechanisms, arrangements and ideas to deal with this fragmentation. New post-NPM steering and coordination practices come in various shapes and names, and current research suffers from considerable terminological confusion. The book first looks at various new organisational arrangements and mechanisms, including whole-of-government, collaborative governance, network governance, and outcome steering. It then goes on to unpack the outcomes these new steering instruments are supposed to achieve, and explores their effect on democracy, power, and the role of government.
