Abstract
Protocol analysis (PA) methodology is discussed in light of its potential for empirical analysis of design problem-solving behaviour. A literature review highlights previous protocol analysis studies in design, with particular attention to Akin's1 PA case study. Presented is a new model-based PA method whereby the verbal behaviour of designers is analysed, quantified, and statistically manipulated to reveal a unique and scientifically rigorous facsimile of problem-solving processes. A recent study based on the above method is outlined, and results of the study are reported.
