Army Human Systems Integration (Army HSI), formerly known as Manpower and Personnel Integration (MANPRINT), is a practice that the U.S. Army uses to make sure human factors such as capabilities and limitations are incorporated into all of the steps during the system acquisition process. Army HSI is the voice of the Soldier, and was initiated in recognition of the fact that the Soldier is a key component of the total system. In order for a system to function optimally, the Soldier must be able to perform required tasks efficiently. Decisions made with the Soldier in mind enhance overall effectiveness and reduce long-term cost. Army HSI helps to ensure that our Soldiers can operate our systems to accomplish their missions to defend our nation.

Army HSI Mission:

Optimize total system performance, reduce life cycle costs, and minimize risk of soldier loss or injury by ensuring a systematic consideration of the impact of materiel design on Soldiers throughout the system development process.

"Army readiness is the unifying concept that keeps us laser-focused as we navigate a deluge of warfighting demands and desired capabilities, which find expression in the modernization of system organizations, equipment, and training. HSI must always ask: what is the risk to soldiers when system changes are afoot, and what impact on soldiers' readiness will result? We must collectively hone and adapt our best HSI tools, methods, and practices, so our soldiers are prepared and equipped not by chance, but by design – because we advocated for and ensured system usability, suitability, and acceptability."
