||How an Architect Created Design Requirements

||There is an anecdotal view that designers, during a conceptual design process,
not just synthesise solutions that satisfy initially given requirements, but also create by
themselves novel design requirements that capture important aspects of the given
problem. Further, it is believed that design sketches serve as a thinking tool for designers
to do this. Then, what kinds of cognitive interaction with their own sketches enable
designers to create novel requirements? The purpose of this paper is to answer this
question. We examined the cognitive processes of a practising architect, using a protocol
analysis technique. Our examinations focused on whether particular types of cognitive
actions account for the creation of novel design requirements. We found that intensive
occurrences of a certain type of perceptual actions, acts of establishing new relations or
visual features on the sketches, are likely to co-occur with the creation of requirements.
This suggests that this type of perceptual actions are the key constituent of acts of
creating novel requirements, and therefore one of the important actions in sketching
activities. This presents evidence of the view that designing is a situated act, as well as
has an implication for design education.
