ABSTRACT
With the CAD/CAM systems available today it is quite possible for some products to progress from concept design through production without requiring full-size physical models or mock-ups to perform any necessary evaluations. This helps to reduce the time scale of product design considerably. However, as most CAD/CAM systems provide little or no information concerning the needs of the end user, there is considerable danger that design decisions may only consider the engineering, styling, legislative, and financial constraints for the product, with the ergonomics issues comparatively unassessed until the design is completed.
