Activities of and time spent by the project dietitian in implementing a custom-designed decision support system for a computer.

Part 1 of this study involved development and implementation of a prototype of Interactive Foodservice Decision Assist Methods (IFDAM) software. A 1-day menu from the Health Center of Methodist Health Services, Inc., which included 161 menu items and 181 ingredients, composed the data base. The prototype was used to test transfer procedures from the mainframe computer at the university to the one at the hospital and to test the program and train users. Three supporting documents were written. The Procedure Manual described methodology for data collection and use of IFDAM at the Health Center. The Data-Entry Manual explained the use of the microcomputer for entering information into IFDAM. The User Manual illustrated the command structure of IFDAM. Part 2 of the study included the addition of data from five cost centers, which were serviced from the central production facility of the Health Center. Six-week-cycle menus and all ingredient files in the foodservice were incorporated into the data base. The data totaled 998 menu items and 660 ingredients. Time spent by the project dietitian on development of data bases and support manuals, completion of data forms, data entry and transfer, conferences, and training totaled 362.10 hours and 898.75 hours in Parts 1 and 2, respectively. The project required 30 months to complete. Problems, classified as equipment, program, or personnel, delayed implementation.
