Among the interesting conclusions drawn by Foz from
his experiment is the importance of simulation during the parti
design as a way of making decisions. Design was better characterized ‘as a learning activity than as an analytic dissection of a formal problem’. If human information processing capacities seem to be the same for individuals, the performance of the skill designer relies in part on his ability to organize knowledge in well structured chunks and to use these chunks in an efficient sequence. Skill designers make more tests on the ideas that occur to them and tend to delay the arrival at a building form proposal. They use three-dimensional representation often, not as a display of a completed design proposal but as a part of the information process.
Such a study seems to have great significance if we really want to inquire as to what could be a reasonable use of automatized methods during the design process. The idea of computer-aided design has to be discarded. The use of these methods cannot be as an exterior and miraculous help whose effectiveness is dependent on the state of the art of a discipline which has nothing to do with architecture (computer science).”
