What is a GDSS? Group Decision Support Systems, are a subset of the much larger family of decision support systems that deal exclusively with groups as opposed to individuals. GDSS's are computer based systems consisting of hardware, software, and procedures that are designed to facilitate the exchange of information in a group setting (Aiken, 1993; Aiken et al., 1994; Donelan, 1993). The facilitation of communication can be generally categorized into several main themes. First, and this is unique to GDSS's, is the ability of the audience / participants to register comments on the discussion at hand in an anonymous manner.
