The basic reasons for computerization are to obtain higher quality and more timely information, to improve decision-making and interagency coordination, to provide more information for policy analysis, and to increase system efficiency. Criminal justice information includes archival information on criminal histories; tactical information relating to pretrial and sentencing decisions; case management information for courts, prosecutors, and the police; and strategic information for program evaluation and policy development. A strong foundation and needs assessment should precede the introduction of information technology. Each project selected for implementation requires management, the assignment of people to do the work, and assessment to determine whether the system works as designed. The available options include off-the-shelf solutions, technology transfer, customization of an existing system, and the development of a custom system. Staff training and attention to issues of privacy and security are also essential. Figures
