Four standards are proposed to assess instruments designed to evaluate group decision process effectiveness. These standards were applied to a multicriteria evaluative instrument based on the Competing Values Approach (CVA) to decision process effectiveness. Participants were 144 regional leaders who participated in a statewide conference of library system professionals. The study used 9 groups and 3 types of raters (facilitators, participants, and observers) in a field setting. The instrument was found to be appropriately insensitive to role differences between raters within groups and appropriately sensitive to differences across groups. The finding of differences between groups is particularly striking because groups similar in composition, using the same decision-making technique, and performing the same task varied substantially in their evaluations. The CVA framework can offer a useful conceptual foundation for evaluating group decision making because it allows evaluators to discriminate between groups in some important dimensions of decision-making effectiveness.
