The value of planning, particularly strategic planning, has long been recognized by both the military and business. Recently, the military has made significant contributions in the area of strategic decision making through the use of war games. Business managers may be able to expand their strategic decision-making judgment by employing the wargaming technology developed by the military. If the wargaming concept is embraced by business, it must serve, as it does in the military, as an aid to decision-making rather than as the decision itself. © 1984.
