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.

"The Army must embrace increasing complexity, albeit with the knowledge that it presents new challenges for system design and training. There can be little question that Army HSI will be central in responding to these challenges."
