Productivity measures in the criminal investigation function

The authors served as evaluators of a Managing Case Investigations (MCI) demonstration project in a major urban police department. Such projects were funded by Law Enforcement Assistance Administration (LEAA) as a follow-up on the Rand Corporation study of the criminal investigation process. This article uses a framework of economic analysis to evaluate the efficiency of the demonstration project. Evaluation shows that the clearance rate of cases rose during the project without the use of additional resources. Impressions gained concerning the appropriate criteria for judging the work of detectives are discussed.
