Multidisciplinary teams have become the norm in design and relates to the complexity of the artifact designed. In this article, we study multidisciplinary teams’ design behaviors by combining protocol analysis, Natural Language Processing and network science. Three teams composed of professional mechanical and electrical engineers took part in this study. Designers engaged in the design activity with similar design processes and spend more cognitive effort on evaluating their design artifact when collaborating. Creating a network of the topic explored based on designers’ disciplines produces their design spaces and illustrates the influence of context knowledge on the design situation. Mechanical engineers tend to tackle user-centered issues while electrical engineers focused more on product related one. For most of the topics covered like with the end users, the product in context of usage, and technological aspects of the product, we observed collaboration between disciplines. Using networks to represent design spaces and design processes could become a tool to support team design collaboration.
