Group decision making and perceived decision success: The role of communication medium

The authors investigated the role of communication medium on the relationship between team member perceptions and decision success. Seventy-three 3-person groups participated in a consensus intellective task either face-to-face (FTF) or via computer-mediated communication (CMC). The participants also assessed their group's decision success and team member competencies. CMC group members' success perceptions significantly predicted their group's performance, but FTF group members' perceptions did not. Furthermore, only CMC group members' judgments regarding their group's problem-solving ability significantly predicted their decision success. Last, judgments of decision success mediated the relationship between perceptions of members' problem-solving ability and decision success only for CMC group members. Implications are discussed.
