Compstat and Organizational Change in the Lowell Police Department by James Willis, Stephen Mastrofski, David Weisburd, and Rosann Greenspan, examines the special challenges and opportunities that arise when a small department tries to institute a program of organizational change that originated in much larger agencies. The report, from the Police Foundation, provides a detailed description of the Lowell, Massachusetts Compstat program; explains the benefits and challenges of implementing the various key elements of Compstat; and draws on our knowledge of the Lowell experience to provide some insights into Compstat's future in law enforcement.
