The development and delivery of military training on new weapon systems is dependent on the identification of training system requirements early in the weapon system life cycle. An automated interface between Logistic Support Analysis (LSA) data and the Instructional Systems Development (ISD) procedures will provide training developers with a means to assist in identifying training requirements earlier in the weapon system acquisition phase. This paper discusses the design and development of such an interface for the C-17 aircraft being developed by McDonnell Douglas Aircraft Corporation. The interface development includes three objectives: (a) tailoring of an existing computer-aided LSA data system for an emerging weapon system; (b) developing automated ISD worksheets; and (c) demonstration of a prototype interface of the ISD automated worksheets with the aircraft system LSA engineering data. The implications of the ISD/LSA interface are twofold. First, it will aid in the development of training by providing a more efficient method of identifying training requirements earlier in the weapon system acquisition process, and second, it will provide an audit trail for LSA and ISD data being utilized in training requirements development.
