A variety of prosecution management information systems (MIS's) has been developed and implemented over the last few years to assist prosecutors in their day-to-day operating functions and in managing resources. This study was designed to identify and describe the nature and extent of prosecution MIS usage and the problems, costs, and benefits of such usage. In addition, the evaluability of these systems was investigated to determine the extent to which they could be evaluated objectively in a later indepth study. Information was gathered through a mail survey of 594 prosecutorial agencies and through site visits to 17 locations where MIS systems are currently in operation. Furhtermore, a literature survey and telephone contacts with individuals throughout the judicial system were conducted. Sections focus on background information, the evaluation framework, descriptions of prosecution MIS's, a review of the state-of-the-art and state of knowledge about prosecution management information system, findings, and the design approach for the planned, indepth evaluation. The information systems are described in a format that facilitates comparison among various projects. The findings are presented in two parts. The first presents the quantitative results of the mail and telephone surveys and site visits, and the second examines the results of all aspects of the data collection and analysis and presents judgmental assessments. Data tables, flow charts, and reference lists are included. (See related documents 74467 and 74468.) (Author abstract modified)
