Abstract
Periodically it is desirable for a discipline to examine its underlying goals, assumptions and methodology. Such an examination may lead to a new way of looking at the discipline and hence to a new and more productive methodology. Human factors was examined in terms of the following topics: (1) the way human factors is defined and its differentiation from other disciplines, (2) its relationship to the man-machine system and to system development, (3) human factors goals and assumptions and their implications, (4) human factors research needs and criteria for effective human factors research, (5) human factors successes and failures in accomplishing its goals, (6) the communication of human factors information, and (7) the adequacy of human factors methodology in terms of the problems it must solve. A series of eighteen essays are presented in this report discussing a number of hypotheses relating significantly to the study of human factors.
