The U.S. Army's Manpower and Personnel Integration (MANPRINT) requirement is designed to fully integrate the Materiel Acquisition Process (MAP) to include Human Factors Engineering (HFE), Manpower, Personnel, Training, System Safety, and Health Hazard Assessment early in the cycle. This effort represents an excellent opportunity for HFE practitioners to influence the system design process with considerations for the human component. However, MANPRINT also represents the necessity for a variety of disciplines to work together and communicate data during all phases of the MAP. This task requires full documentation of all efforts and utilization of valid methodologies. The broad base of data contained within HFE analyses gives it a critical role in the integration process.
