Collaboration between government agencies, an old joke goes, is an unnatural act committed by nonconsenting adults. Eugene Bardach argues that today's opinion climate favoring more results-oriented government makes collaboration a lot more natural--though it is still far from easy. In this book, Bardach diagnoses the difficulties, explains how they are sometimes overcome, and offers practical ideas for public managers, advocates, and others interested in developing interagency collaborative networks. Bardach provides examples from diverse policy areas, including children, youth, and family services; welfare-to-work; antipollution enforcement; fire prevention; and ecosystem management.
