ABSTRACT
Product designers are continually confronted with constraints , standards and guidelines. Therefore one response to this chapter would be is there a need for another set of guidelines? Their effectiveness in supporting the design process can certainly be questioned. Research by Klein and Brezovic ( 1986) asked designers to rate various types of human factors information and found that technical literature was rated least effective, with personal experiences and experimentation supporting design decisions rated the most useful. Designers complained that the literature was often difficult to apply to their particular design problem.
