The Human Factors Evaluation Mentor (HFEM) will have broad utility in other government and commercial applications where formal, systems engineering design procedures are used and where human - systems integration (HSI) is a salient requirement. Additionally, the HFEM will benefit smaller enterprises that do not have Human Factors Engineers on staff. Exemplar applications for the HFEM of some criticality are easily stated. Within government, these include DoD warfighter's equipment and vehicles, the FAA's evolving systems for air traffic management in the NEXGEN environment and its certification of cockpit avionics developed by third-parties. In the commercial realm, the HFEM can be a contributor to the development of medical equipment of all sorts. Human Factors Evaluation (HFE) is a recognized,important element in the systems design and development process. The new edition of NASA's Systems Engineering Handbook explicitly addresses the requirement for HFE for the first time. The Human Factors Evaluation Mentor (HFEM) will both expand the use of HFE in NASA's engineering design process and improve, if not completely assure, the quality of the results. Moreover, the use of the HFEM should add to the overall efficiency of the system design and development process by integrating HFE in the design stream with other engineering evaluations. The HFEM will benefit NASA's programs in information sciences, as its space and aviation programs.
