The need for manpower, personnel, training, and safety (MPT&S) guidelines and constraints can originate at both the specific weapon system and aggregate system levels-whereas the typical Government acquisition team specializes only in information at the first,(weapon system design) level. The amount of organizational support provided them is also not adequate to their task. In order to help integrate MPT&S factors during weapon system acquisitions, the Government needs: (a) enhanced analytic capabilities to analyze total system tradeoffs between man and machine in the performance, maintenance, and support of system tasks; (b) interactive communications with experts in system utilization policy and aggregate system constraints; (c) MPT&S-oriented incentive systems for Government, as well as for contractor, personnel; and (d) a strong centralized headquarters advocate for MPT&S factors with the authority to establish policies and procedures for acceptable MPT&S guidance and control. Specific control guidance is also needed by Government acquisition teams and teams of contractor personnel. For this purpose, recent case studies of Government guidance and control were analyzed, and two lists of "do's" and "don'ts" were developed.
