In order to measure the subjective performance of the collaborating teams, we asked the participants to rate the collaboration for the three tasks separately. For Task 1 we asked if the team shared their profile information well and listened carefully, for Task 2 we asked if the brainwriting was done in an organized way and if ideas were jointly created, while for Task 3 we asked if the role assignment process was clear and effective, and whether its state was visible at all times.
