The organizational context of human factors engineering.

Human factors engineering concerns the design of equipment in accordance with the mental and physical characteristics of operators. Human factors engineers advise design engineers, but the organizational context limits their influence and restricts their perspective. The discussion of organizational context in this paper explains why military and industrial top management personnel are indifferent to good human factors design and shows how the social structure favors the choice of technologies that centralize authority and deskill operators and how it encourages unwarranted attributions of operator error. The role of equipment and system design in shaping cognitive maps and mental models is explored, and the technology-social structure paradigm is questioned.
