24. CSCW – Module 0 – Page 24 P. Dillenbourg & N. Nova CSCW: Objectives  To analyze the impact of a groupware system on the cooperative processes. This requires constructing an experiment and analyzing team interactions with both qualitative and quantitative data analysis techniques (  project 1)  To specify a groupware system that supports specific teamwork processes. This requires analyzing the process to be supported and understanding the relationship between groupware features (architecture and functionalities) and cooperative processes. (  project 2)
