This work analyzes the central role of interpretation in non-routine design. Based on this analysis, a theory of computer support for interpretation in cooperative design is constructed. The theory is grounded in studies of design and interpretation. It is illustrated by mechanisms provided by a software substrate for computer-based design environments, applied to a sample task of lunar habitat design. Computer support of

Software design methods share many characteristics with design methods in other fields. All these methods are the progeny of philosophies of design that are in turn influenced by more general philosophic movements. This essay begins with the influence of philosophies of science on the study of design, highlighting the effects on design discourse of Cartesian rationality, the hypothetico-deductive account of scientific progress, and Kuhnian paradigms. Next, the influence of the constructivist and humanist movements on design thinking are considered, culminating in the introduction of a philosophy of design based on hermeneutics, or interpretation. The influence of design philosophy on software design methods begins a categorization of several software design methods according to the design theory framework, with some emphasis on design methods that support a hermeneutical style of design. Some justification for a pluralistic approach to software design methodology rounds out the essay. ...
