JIMS systems constitute the primary use of the Harris County Information Technology Center (ITC) computer system consisting of an IBM Z9 mainframe, over 15,000 terminal definitions and 3700 printer definitions.

JIMS consists of professional information-systems and support personnel, many with over fifteen (15) years of service with the county. The general organization is based upon the area and type of services delivered. Functional areas are controlled by supervisory staff provided with appropriate technical personnel.

Department direction and prioritization of work effort is determined by the end users through representation on the JIMS Executive Board, the JIMS Management Committee, and the JIMS Technical Group although the operating budget is approved and authorized by Commissioners' Court.
