Abstract : The United States Air Force (USAF) is currently faced with a rapid proliferation of micro-computer-based training systems. This rapid growth is an attempt to increase training productivity to compensate for increased training demands and decreasing training resources. However, noncompatible training systems can actually increase costs for training administration, support, and development. This study addresses these problems by examining the feasibility and benefits of developing a generic or generic family of compatible computer- based training hosts. The functional requirements of a sample of USAF training applications were identified, their common characteristics were then consolidated, and the resulting set of basic generic systems were merged in various combinations to form candidate generic micro-computer families. These families were then evaluated for their effectiveness as training hosts. The conclusion was that a family of generic systems is more effective than a single generic system and that the identification of USAF generic computer-based training host family is feasible.
