The effects of the two modes of video-conferencing on the quality of group decisions

This paper reports a set of ongoing experiments motivated by the observation that the design of group decision processes is crucial to the success of electronic meeting room usage. Decision processes can be designed with more emphasis either on informational (generating and structuring topics) or communicational (discuss issues) interactions. Our problem is that, given a particular case intended to be discussed in an electronic meeting room, we do not know how to design the meeting for best performance. The paper builds a framework for studying this problem based on the notion of mediation channels. The experiments already made confirm that quality of results varies when different channels are used, and show that meetings designed without communicational interaction support result in solutions with inferior quali ty.
