Downsizing the Department of Defense (DoD) means accomplishing more with fewer people. Enlightened design that considers all requirement and interaction issues simultaneously is the key to productivity. In the past, human issues have been difficult to quantify or depict during the systems engineering process. Recently, there has been an explosion of affordable HSI technologies. Despite the new DoD directives that require HSI analyses throughout acquisition, it is difficult to identify the most appropriate technology for HSI analyses. Defense acquisition managers, contractors, and the HSI research and development (R&D) community need a database of information about HSI tools, databases, and test facilities. They need this database to identify technology available in each of the Liveware domains of Manpower, Personnel, Training, (MPT) Safety, Health Hazard Prevention, and Human Factors Engineering (HFE) and to fully integrate human consideration into the acquisition process. However, no comprehensive catalog of HSI technology exists. Under the sponsorship of the Office of the Assistant Secretary of Defense (Force Management and Personnel) HSI office and North Atlantic Treaty Organization (NATO) Research Study Group.21 (RSG.21), TPDC and CSERIAC are surveying the HSI community for a comprehensive database of HSI technologies, an ambitious effort requiring the help of all HSI technology developers, owners, and users. This paper reviews previous HSI-related technology studies. It supports the thesis that a comprehensive survey and database are needed to improve prioritization of HSI technology R&D aid in HSI technology identification and use; and take full advantage of the new acquisition climate. It also describes the survey and database which is now being populated, and highlights the need for HSI community participation.
