The growing importance of teams in design introduces challenges and complications for designers to work effectively. In team work we can make a difference between the individual level and the team level. The individual designers have to tune their personal understandings about the design content to achieve a shared understanding. In this paper we will build a conceptual theoretical framework in which we try to capture the essence of designing within a team. We will show how the team of the Delft workshop 'Analysing Design Activity' associates with this framework. With the outcome of this explorative analysis we will create a basis for further research on this subject.
