This report provides a description of a Computer Aided Training System Development and Management (CATSDM) environment based on state-of-the-art hardware and software technology, and including recommendations for off the shelf systems to be utilized as a starting point in addressing the particular systematic training and instruction design and development model described in MIL STD 961 (often referred to as the Fleet Aviation Instructional Systems Design Model). The functional specifications describe a system of computer programs to assist in successfully and reliably carrying out the Instructional System Development (ISD) process. These programs are designed to lend structure to the activities of persons involved in ISD, as well as to provide a wide range of support functions, including needed data collection and manipulation capabilities for all phases of the process. The remainder of the document deals in detail with the components of CATSDM, conception and development of these components, and recommendations and conclusions made in light of the analysis of existing systems.
