PROTOCOL ANALYSIS OF THE USE OF A CAD SYSTEM IN A HOME DESIGN TASK

The question of how humans design has been approached from a number of perspectives. Analyses have been made of the processes, strategies and problem solving techniques utilized when generating new designs [Finger 89]. One descriptive method to understanding the design process is the use of protocol analysis. This method has been successfully applied to elucidate the stages and decisions inherent in design (see, for instance, [Ullman 86, Adelson 89, Schon 88]).
