Modelling the Design Process in Engineering and in Architecture

Abstract

Models of the design process in engineering seem to have converged upon a consensus represented, for example, by the German VDI model. However, after starting from common origins, models of the design process in architecture have diverged from the engineering consensus, in response to criticisms from both theorists and practitioners. There now appear to be significant differences between the engineering and architectural design models. Criticisms of the consensus model of engineering design have also been made, similar in some ways to the earlier criticisms of the architectural design models. We discuss the similarities and differences between the two consensus models—in engineering and architecture—and identify prescriptive vs. descriptive emphases. We suggest that attempts should be made to reintegrate the two models to improve common features of design education and practice across the disciplines.
