ABSTRACT
Research has suggested that even professional ergonomists tend to restrict themselves to two or three of their favorite methods, despite variations in the problems that they address (Baber and Mirza 1988; Stanton and Young 1998). It is argued that greater coverage of Human Factors and Ergonomics methods is required. The coverage was determined by the range of activities that the discipline Human Factor and Ergonomics is involved in. A systems approach requires each of these activities to be considered. This coverage is defined in Table 1.
