Patterns of managerial traits and group effectiveness
Abstract"The relationship of the distribution of managerial traits within a group to productivity in a complex cooperative task was investigated, using groups of 2, 3, and 4 people. 2 managerial traits, supervisory ability and decision-making approach, were measured by means of self-descriptions obtained from a forced-choice adjective check-list . . . . It was found that neither the average amount of the trait possessed by the group nor the amount possessed by the highest scorer was highly related to the criteria. 2 measures of skewness used . . . were highly related to the criterion of productivity, a correlation of .82 having been obtained between the criterion and the positive skewness of the group on the decision-making approach (DMA) scale."
