Analysis of the Human-System Interface Used in the Program Managers Support System: Software Cost Estimating and Competition Evaluation Modules

摘要

This thesis analyzed the human-system interface used in the program Managers Support System (PMSS) software. The PMSS software is planned to consist of 18 modules that will run as an integrated system on standard Air Force microcomputers. Six modules are presently in prototype form. This research analyzed the human-system interface of two of those modules, the Software Cost Estimating and Competition Evaluation program. Problem scenarios involving software cost estimation and competition evaluation were developed with the assistance of Aeronautical Systems Division (ASD) expert. Fourteen ASD program management persons were chosen as test participants (seven for each module) and attempted to work the problem scenario with the prototype software. The participants were only permitted to view the scenario and program documentation prior to the test. Their critical comments were recorded during the test session and later transcribed. Transcribed comments were categorized and compared to expert guidelines published in the literature. Finally, suggestions for improvement in the human-system interface used in these modules were drawn from this comparison. (kr)
