Group Size, Group Development, and Group Productivity

GDQ Associates, Inc

This research investigated the impact of small and large work groups on developmental processes and group productivity. There were 329 work groups operating in for-profit and nonprofit organizations across the United States in this study. Groups containing 3 to 8 members were significantly more productive and more developmentally advanced than groups with 9 members or more. Groups containing 3 to 6 members were significantly more productive and more developmentally advanced than groups with 7 to 10 members or 11 members or more. The groups with 7 to 10 members or 11 members were not different from each other. Finally, groups containing 3 to 4 members were significantly more productive and more developmentally advanced on a number of measures than groups with 5 to 6 members. Work-group size is a crucial factor in increasing or decreasing both group development and productivity.
