Development of the training system for a major defense system generates a tremendous workload for system acquisition and training professionals. Inadequate management and development of the supporting training system hinder the deployment and operation of a defense system significantly. The armed services and the software industry have developed software tools to assist system acquisition and training professionals. This paper reports the results of evaluating selected tools including GTET {Guidelines for Transportable Education and Training System), TRACES (Training Cost Estimator Systems), TASCS (Training Analysis Support Computer System), and JS ISD/LSAR DSS (Joint Service Instructional Systems Development/Logistic Support Analysis Record Decision Support System). The functions of the tools and considerations for making adoption decisions are described. A global comparison matrix of the tools' functions is presented, and recommendations for improving the tools are provided.
