Abstract: | This study sought to obtain empirical data that either directly supports or refutes the “functional” perspective advanced by recent group decision-making theorists. Specifically, the study attempted to test the general claim that the group's satisfaction of critical task-achievement functions (or requisite conditions) is a better predictor of decision-making performance than the discussion procedures it employs in arriving at a decision. A total of 48 three-member groups were randomly assigned to one of four different discussion formats. The groups were trained to use their assigned format in arriving at a decision regarding a human relations case. Two-way ANOVA revealed no significant main effect for “discussion format,” but a significant main effect for “satisfaction of requisite conditions.” No interaction effect was discovered. The findings thus offer strong support for the “functional” perspective. Other analyses indicated that the satisfaction of certain requisite conditions may be more important than others in determining group decision-making success. |
