Integrated HSI

Abstract

In the conduct of Human Systems Integration (HSI) as practiced by the U.S. Navy, HSI is more than the sum of its parts. While HSI includes the individual domains concerned with addressing requirements for the human in the system, it also includes the interaction of these domains, and the synthesis across the individual domains of the respective requirements for human performance, human behavior, human availability, human productivity, human competence, human well being, and human accommodation. The integration of the HSI domains is achieved at two levels, consolidation of domain activities in support of overarching HSI, and tradeoffs among HSI domains to optimize the integration of the human in the system. At the first level, the seven domains of HSI are integrated among themselves and into the systems engineering process. This integration is achieved through collaboration and cooperation among the individual domains, and a focus on what must be done in each domain at each phase of the systems engineering process to generate relevant domain requirements. The second level of integration addresses the tradeoffs that must be conducted among the HSI domains to achieve the most effective and affordable integration of the human element with system hardware, software, firmware, courseware, procedures, organizations, environments, and information.
