The Manpower, Personnel, and Training (MPT) in Acquisition Decision Support System (DSS) is an Air Force program providing the first integrated tool for addressing MPT requirements during system acquisition and design. New weapon system development and major modifications have historically neglected how our most important and costly resource - people - will maintain and support the fielded system. Inadequate planning for training and deploying the human element has often delayed system operational dates. This DSS will assist acquisition managers and analysts to effectively integrate people issues (numbers, characteristics, proficiency) with equipment (aircraft) early in the acquisition cycle. Acquisition specialists can use the structured analysis approach provided by the MPT DSS to ensure that system people costs are affordable, jobs are properly structured, and people are trained prior to the system becoming operational. The MPT DSS is being designed to support the Human System Integration requirements, now directed under DOD Instruction 5000.2.
