Facilitating space-time differences, group heterogeneity and multi-sensory task work through a multimedia supported group decision system

Group work outside of the decision laboratory exhibits several interesting characteristics. Communication is frequently off-line, particularly if individuals are geographically separated. Group members have different backgrounds (e.g., in focus groups, mixed customer and company groups) and do not necessarily share the same information or values. Tasks can have significant visual and auditory components, as for instance in product development. While these characteristics are by no means exclusive, they represent important factors which now can be addressed by multimedia supported group decision systems.
The article discusses these and related aspects of group decision making and explains design alternatives to handle them. Proposed technology solutions include a multimedia group communication and e-mail facility, a visualization tool ("virtual tour guide"), a multimedia directory, and a problem structuring tool. The software tools have been recently developed. Some initial experiences with the technology are also presented. © 1995.
