ABSTRACT

    Intuitive design, as carried out by architects, product
designers, and some engineers, is analyzed as a problem solving
task within the framework of an information processing theory
of cognition. A study of intuitive design processes was
carried out utilizing four protocols as experimental data. Two
of the protocols are presented in this report in their entirety.

From the protocols were identified the information used, the
transformations carried out on the information, and some of the
administrative processes directing particular sequences of
activities. Analysis of the protocols led to an operational
model of design and hand simulations largely replicating one
protocol. Fundamental issues of design methodology are outlined.
Of particular interest is the insight offered into semantic memory
retrieval processes utilized by designers and the representational
languages used in complex problem solving.
