Teams of 3-4 members gives optimum productivity and team development.

I just read a very interesting study on group size vs performance. According to this study we really should always aim to be working in groups of 3-4 members and not the 5-9 that is typically quoted.
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.
