The trend in the United States military services is to design training programs as total systems rather than as collections of courses or blocks of instruction. This trend has highlighted the need to design an integrated aircrew training management information system (ATMIS) to ensure the cost-effective operation, maintenance, and evaluation of the total system throughout its life cycle. For the past several years, the Aircrew Training Research Division of the U.S. Air Force Armstrong Laboratory has been engaged in a field research program to identify the functional characteristics and information/data requirements of ATMISS. A number of military and contractor aircrew training systems have been reviewed and analyzed. The purpose of this paper is to discuss some of the findings and to propose a systematic approach for the design of ATMISs, with particular emphasis on the identification of comprehensive, multiuser information requirements. This approach is presented in the context of a new, contractor-designed and supported aircrew training system, which is intended to replace an existing Air Force system. The composition and use of representative multi-user working groups, a baseline analysis of the existing ATMIS, and procedures for determining the information requirements posed by the new system are discussed. These information requirements are developed from an organizational perspective. It is suggested that the entire sequence of ATMIS design, development, and operation be subjected to a rigorous test and evaluation process, including an assessment of its impacts on organizational performance.
