The procedures for producing a report on departmental service to nonmajors are described in detail. The objective was to provide information for decision-making needs without reliance on the standardized pre-packaged models. An alternative to the Induced Course Load Matrix (ICLM) of the Resource Requirements Prediction Model (RRPM) package of the National Center for Higher Education Management Systems (NCHEMS) provides concrete information as opposed to symbolic or ratio information. Since the ICLM as contained in the NCHEMS package was too complex for practical purposes, the IRS145 was developed to produce a two-page departmental report on student credit hours generated by undergraduate majors. IRS145 is a computer job primarily written in Easytrieve, with one program written in PL1. Detailed explanations are provided concerning the files and the programs. The fields include major, classification, quarter, course number, and quarter credit hours for the course. The uses of the IRS145 versus the ICLM are briefly contrasted. An explanatory memo for department heads regarding the approach is appended. (SW)
