The model for planning groups presented in this paper is an attempt to provide varying levels of organizational leaders with a device to increase planning efficiency and effectiveness. The planning process is highlighted as it might be viewed through the eyes of the individual responsible for completion of the planning task. The major emphasis is on pointing out those aspects of individual and group behaviors which may affect the planning effort in a group setting. The prospective planning manager is provided with guidelines as to how he might develop a sensitivity to characteristics of individual and group behaviors, in order to optimize individual as well as group contributions to the planning activity. An extensive reference listing is included. (Page 29 may reproduce poorly.) (Author/MLF)
