Analytical Methods for Determination of Training-Device Requirements

Training devices must be conceived of some time after the conceptualization of the systems they simulate. They must be delivered earlier than the systems they simulate. They compete for development funds with the system itself and with one another. There is thus a need for a logical analytical tool, which can operate upon the guesses and assumptions that, early in system development, are all that are available, in order to generate training-device needs, priorities, values, and specifications. This paper describes the development of such a logical tool. The process developed has been used to develop training device requirements for a large number of varied military systems. Though its results are sensitive to the assumptions with which it is entered, the method does provide a clearer statement of the training devices that will be needed than other methods appear to do.
