The Art and Craft of Policy Analysis is a classic work of the Public Policy discipline. Wildavsky’s emphasis on the values involved in public policies, as well as the need to build political understandings about the nature of policy, are as important for 21st century policymaking as they were in 1979. B. Guy Peters’ critical introduction provides the reader with context for the book, its main themes and contemporary relevance, and offers a guide to understanding a complex but crucial text.
