The Human Systems Integration Technologies, Tools, and Techniques (HSIT3) Survey was implemented to solicit input from HSI subject-matter experts (SMEs) and MANPRINT practitioners to identify the user's requirements for an updated HSI practitioner's guidebook. The survey was divided into three major sections: (1) Demographics; (2) MANPRINT Implementation; and (3) MANPRINT SOAR Recommendations. The survey was sent electronically to 70 MANPRINT practitioners and SMEs representing the Army, Air Force, Navy, FAA, industry, academia, the UK and Canada. The survey responses that were returned varied in the level of detail. It appears that individuals concentrated their efforts on areas with which they were most familiar.
