The Role of the Human Factors Designer in an Integrated Computer System

Abstract

This paper addresses the changing role of the human factors professional in the design of integrated computer systems for telecommunications engineering. Specifically, with the advent of such software, the human-computer interface is at times replaced by a computer-computer interface. With humans removed from the direct processing function, should human factors designers be removed from the design function as well? Our experience has shown that there is in fact a continuing need for our expertise, as long as humans remain in the process in any role. With the changing roles of our users, however, the focus of our efforts should change. The quality and utility of an automated computer system will be optimized by the early and persistent involvement of human factors designers in task analysis, user identification, function allocation, system design, user education and quality assurance.
