An OTSM-TRIZ Based Framework Towards the Computer-Aided Identification of Cognitive Processes in Design Protocols

Abstract

This paper presents an original approach for the analysis of design protocols. It presents a coding scheme based on the OTSM-TRIZ Network of Problems, so as to map the protocols by both considering design moves and their mutual relationships with links. Stemming from this coding scheme, the authors propose a novel set of rules for the identification of cognitive processes to be integrated into a Computer-aided tool, so as to reduce the time employed for the analysis of design protocols. The five preliminary tests carried out to verify the potentiality and the feasibility of the approach have demonstrated that it provides good results both in terms of quality and in terms of time-savings for the whole protocol analysis.
