The social disorganization theory developed by Shaw and McKay led to the conclusion that if disorganization is the root of the crime problem, organization is the solution. However, a growing set of data suggests that such crime control efforts may not be especially effective. The reformulated model is sometimes called the systemic model of neighborhood crime. This model emphasizes ongoing patterns of information exchange a reflected in the networks and ties among the components of a system. It also recognizes that an organized neighborhood may be reflected in a variety of social structures, that aspects of a system's structure may change without the dissolution of the system itself, and that a system is open. This model focuses on the regulatory networks that exist within and between networks and has important implications for the development of crime control programs. The three aspects of particular relevance are the importance of the neighborhood's formal and informal interactional systems in controlling crime, the need for networks that span all the groups in an area, the importance of effective relationship among a neighborhood's residents and local associations and the metropolitan area's primary public and private institutions that channel resources to urban neighborhoods.
