A questionnaire was designed to aid the interested professional in describing, characteristics and analyzing his game, model, or simulation, and tested on a number of Department of Defense (DOD) games. An over-riding goal for the questionnaire was to produce a categorization scheme for games in general. The different sections of the questionnaire were designed to provide information on basic purposes, use benefits, and costs; characterization and description; man-machine interaction necessary for the game, simulation or model; and an open-ended assessment of the game, simulation or model.
