Analyzed group discussions associated with 68 high-quality and 29 low-quality decisions made by comparably informed groups using cross-contact comparison. Found vigilance, second-guessing, and accurate information processing associated with high-quality decisions; faulty information processing and improbable fantasy chains with low-quality…

Supports the "functional" view that it is the satisfaction of critical task requirements (or conditions), rather than the discussion procedures that are employed to do so, that actually determines whether a group will arrive at a low- or high-quality decision. (PD)

Concludes (1) that the relationship between consensus and decision quality tends to merge when the group approaches its task in a systematic and rational manner and (2) that group communication scholars need to be careful about assuming that consensus decision-making necessarily results in more decision-making satisfaction among group members. (PD)

Found no single sequence of interaction phases that led to successful or unsuccessful group problem solving. Successful groups, however, tended to begin their discussions by attempting to analyze the problem before searching for solutions; unsuccessful groups immediately began searching for solutions. (PD)

Found that the discussions of "effective" and "ineffective" groups were distinguished by (1) how the groups examined opinions and assumptions advanced by group members; (2) how the groups evaluated alternative choices; (3) the nature of decisional premises; and (4) the nature of influence exerted by influential members of the group. (PD)

Found that of five "task-achievement functions" examined, two serve as accurate predictors of group problem-solving effectiveness. Specifically, found that (1) a negative relationship exists between group effectiveness and attempts to "establish operating procedures"; and (2) a positive relationship exists between group…
