Group Decision Process Effectiveness

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 to decision process effectiveness. In a study using nine groups and three 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. Ratings of facilitators and participants within groups were the most consistent, although their ratings diverged on four of the effectiveness scales.
