Previous research on brainstorming and nominal group techniques has focused primarily on theirability to generate ideas without examining the impact of these procedures on actual group decision making. This experimental study found no difference in the decision quality of untrained, brainstorming, and nominal groups. However, brainstorming and nominal group members were more satisfied, felt their groups used a more effective process, andfelt they communicated more effectively than untrained groups. Such results suggest that the impact of these techniques goes beyond their ability to generate ideas by affecting group process and communication in positive ways.
