Problem-oriented policing initiatives are one important form of crime prevention, and they offer opportunities for learning about implementation success and failure. Problem-oriented policing initiatives can succeed or fail for a variety of reasons, among them: inaccurate identification of the probk?n, inaccurate analysis of the problem, inadequate implementation, or application of an incorrect theory. This paper draws upon both the research literature and reports on problemoriented policing initiatives to identify those factors that best explain why action plans do or do not get implemented. It identifies and provides examples of five clusters of factors that help explain implementation success or failure: (I) characteristics, skills, and actions of project managers; (2) resources (3) support and cooperation external to the police agency; (4) evidence; and (5) complexity of implementation.
