Decision Development in Computer‐Assisted Group Decision Making


Research output: Contribution to journalArticlepeer-review


New computer technologies to aid group communication and decision making are becoming increasingly widespread. This study analyzes how one such technology, a group decision support system (GDSS), affected how group decisions developed over time. The study contrasted decision paths in groups using the GDSS with groups using the same procedural structures incorporated in the GDSS manually and with groups using no procedural structures. A flexible phase mapping method was employed to map group decision paths. The resulting set of seven decision paths varied in both sequence and number of decision phases. An optimal matching procedure was used to compute similarity measures among the 40 paths, and cluster analysis and multidimensional scaling were used to generate an empirical taxonomy of decision paths. Results indicated that the nature of decision paths varied both across the three conditions and within conditions. The decision path types were also related to three outcome variables: consensus change, perceived decision quality, and decision scheme satisfaction. Results indicated that those decision paths that most resembled logical normative sequences had superior outcomes to those that did not.
