Examining the conflicting results of GDSS research

The growing interest in group decision support systems (GDSS) was supported by, and gave rise to, a burgeoning academic literature on GDSS during the 1980s. However, GDSS research is now rare. One possible reason is the difference between field experience and many experimental studies. Another reason is that GDSS research over the past years mainly focused on decision rooms. The important question posed is: what are the reasons for the conflicting results of GDSS research? The contradictory findings among GDSS studies are indeed a problem if academic research is to be applied effectively in business settings. Now that group collaborative support is becoming more widespread, it is natural to wish to achieve a better understanding of the implications for organizations in their adoption of GDSS. Thus, this study systematically reviews existing GDSS studies and explores the probable reasons for inconsistent findings.     

GDSS' formative fundaments

A hermeneutic analysis of current group decision support systems (GDSS) is undertaken, interpreting their functionality, motivations, and usage to uncover theoretical/philosophical bases. GDSS treat decision making as a rational aggregation-and-selection of options (take a given) and support it as a production task conducted as if participants were remotely distributed. Employing avenue framework, this is analyzed as evidence for consistent, fundamentalcognitivism andobjectivism deriving from relevant historical influences. The contextualization and dialogic interaction (give and take) undervalued or ignored in current GDSS are identified as key issues for work toward constructively augmenting such systems.This interpretive analysis, originally appearing as Chapter 2 in Whitaker (1992), was developed at Umeå Universitet (Sweden) with guidance (and insightful challenges) from Professor Kristo Ivanov and Professor Emeritus Hans-Erik Nissen, to whom the author is grateful. The transformation of that material into a standalone article was greatly facilitated by the cogent comments of this journal's reviewers, to whom this author is similarly grateful.

A metalanguage design for sessions with group decision support systems

This paper proposes a metalanguage for representing communication among participants in a session of a group decision support system (GDSS). Such a vehicle can be used for setting standards and designing specific user interfaces with GDSS.Three different roles of participants are identified: chairperson, chauffeur and regular participant. The tasks and activities of each role are analyzed. Based on the analysis, communications requirements are derived. The requirements lead to a design of a metalanguage consisting of 15 different commands. The paper concludes by displaying the structure and syntax of each command.The work described here is conceptual and could be considered as a proposal for GDSS language design.

The effects of a group decision support system on culturally diverse and culturally homogeneous group decision making

Considerable research has been conducted over the last decade on the effects of using Group Decision Support Systems (GDSS) in group decision making. Studies have examined the influence of GDSS on such variables as group task, size, quality of decision, and satisfaction with the process. However, only a few studies have focused on the use of GDSS and its interaction with group composition. This study compared the effects of group decision making, both with and without GDSS technology, on culturally diverse and homogeneous groups. Group performance was measured by the number of non-redundant, realistic ideas and the quality of solution produced in response to posed problems. The GDSS used in the study was Vision Quest. Groups using it, regardless of cultural make up, developed a significantly higher number of non-redundant, realistic ideas than groups that did not. Furthermore, among groups using the GDSS, culturally diverse groups produced a significantly higher number of non-redundant, realistic ideas than homogeneous groups that used the GDSS. Implications for diversity management and group support research are suggested.

Evolution in Groups: A Genetic Algorithm Approach to Group Decision Support Systems

Certain tasks undertaken by groups using Group Decision Support Systems (GDSS) can be viewed as search problems. These tasks involve arriving at a solution or decision where the problem is complex enough to warrant the use of computerized decision support tools. For these types of GDSS tasks, we propose to model the information exchange and convergence toward a solution by the group as a simple genetic algorithm. The simple genetic algorithm is a generalized search technique that is based on the principles of evolution and natural selection. Simply put, the best points in the current population are more likely to be selected and combined through genetic operators to determine new points. We propose that groups using GDSS to address certain tasks behave like a simple genetic algorithm in the manner in which possible solutions are generated, enhanced and altered in attempting to reach a decision or consensus.
