Strategic knowledge in design: a compositional approach

In interactive design processes, strategic decisions are made at different levels. To support designers, design support systems need to include corres ponding strategic knowledge at these levels. In this paper, three levels of strategic interaction and strategic knowledge are identified within a comp ositional model of design. These levels are identified in reasoning about t he manipulation of requirements and their qualifications, reasoning about t he manipulation of design object descriptions, and reasoning about design p rocess co-ordination. Instances of strategic knowledge illustrate the diffe rent levels. (C) 1998 Published by Elsevier Science B.V. All rights reserve d.
