This is a must read for anyone involved in working with a jail information system (JIS). “With the increasing focus on cost efficiency and the avoidance of wasteful spending, jail administrators must under¬stand the importance of the potential data at their disposal and strategically plan for faster and more effective forms of data collection, storage, and analysis. [This guide] encourages jail administrators to consider the design and implementation of a jail management information system (MIS) that is tailored to the specific needs of their institutions, is more cost-effective, and is easier to use. The data they are able to collect, store, analyze, and apply to the correctional setting translates to more effective jail management, more realistic short- and long-term goals, the ability to track trends, a more systematic way to measure performance outcomes for the institution and its staff, and pertinent information on the offender population” (p. v). Chapters comprising this manual are: why jails need to become intelligent; measurement of jail performance and key correctional policies; data that most jails are required to collect; data uses in policy analysis and organizational management; required skills for jail information systems; planning and developing information systems; implementing information systems; and requesting proposals for information system development and selecting vendors. Appendixes cover: what drives information needs; sample of a data dashboard; overcoming the hurdles of jail information systems; case example—Contra Costa Jail, Martinez, CA; case example-- Kent County Jail, Grand Rapids, MI; evaluating your JMS system support and usability features; and “Measuring What Matters”—Kent County Correctional Facility Annual Statistical Report (https://www.accesskent.com/Sheriff/pdfs/2012_Annual_Statistical_Report.pdf).
