Integration of manpower, personnel, and training (MPT) planning systems is needed at both the specific weapon system and aggregate levels in order to avoid disconnects and unexpected consequences for functional area managers. Some recent reports on the need, for MPT integration are reviewed, and a number of MPT integration needs are identified. New systems that are already under development in order to meet these needs are described. The new MPT planning systems can be organized into three categories: (1) the consolidation of MPT guidelines; (2) the use of computer-assisted techniques for MPT tradeoffs, multi-source input aggregation, and aggregate systems management; and (3) the use of incentives for timely and accurate MPT planning by contractors and aggregate systems managers.
