The Department of Homeland Security (DHS) requires general human systems integration (HSI) criteria for the design and development of human-machine interfaces for the technology, systems, equipment, and facilities employed by its user population. HSI is the relationship between humans and their environment and in particular how systems are designed and used relative to that relationship with the goal of ensuring a safe and effective environment that meets the mission. In general, HSI addresses hardware, software, and processes. However, systematically adopting and applying HSI criteria within DHS will be a challenge because of the departments large and extremely varied user population. The DHS personnel who operate and maintain the departments technology and systems carry out a variety of different tasks in operating environments ranging from airports and border points of entry to subways and Coast Guard vessels. Other DHS users include public health officials; state and local first responders; travelers to be screened; bystanders; and the general public. NIST acknowledges that developing and adopting appropriate HSI standards in these areas will take time roughly three to five years. This document offers recommendations on steps DHS can take in the relatively near term to improve its usability posture and build an HSI-oriented organizational culture.
