This handbook is designed to assist community college administrators in using the various reports generated by the facility inventory and utilization subsystem of the Illinois Community College Board management information system. Among the reports generated by the subsystem are: room utilization report, campus classroom usage report, room use mapping by instructional type, room use mapping by utilization rate, building inventory summary, room inventory by room type, room inventory report, building inventory report, and facility inventory report. The room utilization and classroom usage reports are designed to display data by course enrollment, time of day, day of week, type of course, and to accommodate flexible "open" and "to be arranged" courses and laboratories. A brief explanation of the salient characteristics of each type of report is included as are lists of options which the prospective report user may utilize according to his needs for facility inventory/utilization information. Sample computer output for each type of report generated by the subsystem are included in this guide. (JDS)
