This paper basically describes part of our current research on the role of social aspects in collaborative design. Most part of this research, up until this stage, is theoretical research, which is our attempt to imply theories in social psychology in collaborative design. In order to step further towards empirical research we needs tool for the investigation. Discussion on this paper is built upon our attempt to develop this tool. Considering this context the discussion can be observed into two sections. First part is basically summary of our theoretical research to this point. Based on these theoretical backgrounds we discuss our research on defining and developing the tool in the second part. The tool is basically a prototype of design process representation system which is expected to be used as our tool for next stages of this research, investigating the role of social aspect in the real practice of collaborative design.
