summary The design engineering process is analysed from a cognitive ergonomics point of view, relating it to models of problem-solving and cognitive skills. Observations from several Swedish studies are discussed in this framework. Results indicate that CAD systems require some re-thinking; in particular concepts related to the computer storage have to be incorporated in the problem space of design. As to heuristics, CAD systems seem to offer a wide variety of working. Cognitive skills related to CAD seem to be easily acquired, although the transition between different CAD systems will cause some initial problems. In general it is found that current CAD systems mainly support the detail design phase. Some ideas for future systems which would support the conceptual design phase in addition are discussed.
