Groups over time: What are we really studying?

Researchers in the area of group support systems have recently begun to conduct studies of groups using technology working over time on common tasks. Few of these studies take place with real groups in organizations, where groups work on a single task over time, and where tasks have consequences. Few of these studies investigate models of group development and process other than Tuckman's unitary sequence model from 1965. The authors summarize what work has been done in the area of group support system groups over time, what has not been done and why and where we should go from here.
