The discourse of small groups of 3-4 adults enrolled in a graduate business course was audio-recorded as they participated in a computer-supported simulation in which the group represented a firm and worked over a series of eight sessions in making a series of decisions. Discourse transcripts were analyzed using a coding scheme that classified utterances expressed during group interaction as types of topic-talk (constituting a part of the activity itself) vs. meta-talk (reflecting on the activity). Supporting our hypothesis regarding the importance of meta-level discourse about group process in a group's achieving coordinated action and a successful outcome, analysis suggested that discourse about the group's process, but not discourse about individuals' actions, was associated with superior group outcomes.
