Eugene Bardach has been teaching graduate-level policy analysis workshop classes since 1973 at the Goldman School of Public Policy, University of California, Berkeley, in which time he has coached some five hundred projects. He is a broadly based political scientist with wide-ranging teaching and research interests. His focus is primarily on policy implementation and public management, and most recently on problems of facilitating better interorganizational collaboration in service delivery (e.g., in human services, environmental enforcement, fire prevention, and habitat preservation). He also maintains an interest in problems of homeland defense, as well as regulatory program design and execution, particularly in areas of health, safety, consumer protection, and equal opportunity. Bardach has developed novel teaching methods and materials at Berkeley, has directed and taught in residentially based training programs for higher-level public managers, and has worked for the Office of Policy Analysis at the US Department of the Interior. He is the recipient of the 1998 Donald T. Campbell Award of the Policy Studies Organization for creative contribution to the methodology of policy analysis, and is a fellow of the American Academy of Arts and Sciences. This book is based on his experience teaching students the principles of policy analysis and then helping them to execute their project work.
