ABSTRACT
New systems, whether defi ned as implementation of new technology or as integration of legacy systems, are still populated by people. Th ose people may be remotely placed with respect to the hardware and soft ware, but they continue to contribute their capabilities and limitations to the overarching system. Success of these systems is still related to meeting the operational capabilities and depends on the performance of the interrelated humans at expected levels. Achieving the desired operational capabilities is particularity important to the developers of complex systems. Th ese complex systems are used by the military, power generation, and in other large organization or infrastructure entities including transportation. Th ese all require large complex organizational implementation and technical solutions. In recent years, the human systems integration (HSI) approach has begun to be adopted as a user-centered approach for the design and implementation of advanced technology and automated systems. Th e HSI approach links human-based, hardware-based, and soft ware-based domains through the systems engineering process. HSI has identifi ed soft ware toolsets and processes to support the challenging decisionmaking aspects of materiel acquisition.
