Sources and types of knowledge book
Goel (1995) argues from his analysis of a very limited set of experimentally gathered design protocols that, as they proceeded, the primary source of
knowledge moved from being the design brief and the experimenter to being the subject or designer. As we saw in the previous chapter, Goel broke the design process down into a series of stages which he called ‘problem structuring’, ‘preliminary design’, ‘refinement’, and ‘detail design’. We also saw that there is other evidence that challenges such a strongly linear model. However, what is interesting here about Goel’s data is that the designer was the chief source of knowledge in all four of his stages. The designer was the source for about half the knowledge statements in the first stage and over 90 per cent in the subsequent three stages. This certainly strongly suggests that the vast majority of the knowledge used to solve the design problem was brought into the process by the designer.
