Review of the hardback: 'In both theory and practice, the notion of 'performance' has become one of the big drivers of public sector action. But there's been painfully little careful thinking about what it is, how it works, and how it might transform democratic government. This book is a superb and path breaking contribution-one that builds a strong, effective foundation on which further work in this burgeoning field can build.' Donald F. Kettl, Director, Fels Institute of Government, University of Pennsylvania
