Team Effectiveness

What is the ideal team size?
If you’re finding it tough to accomplish much with a team project you’re working on, ask yourself if you have too many heads and hands involved in the task. According to psychologist Ivan Steiner, “each time you add a person to a team,
productivity goes up, but so do inefficiencies”. Tasks such as group coordination gets trickier. This has and continues to be the case. Back in 1970, two Harvard University professors asked large and small teams to perform several tasks. They asked them whether they felt their group was too small or too large for the task. From the feedback, they determined an  ideal team size of 4.6 persons. Although it may be difficult to have less than a whole person working on your team (just kidding), the bottom line is that for maximum efficiency, smaller is better. Of course, as I mentioned earlier, with larger teams you bring more skills as well as more inefficiencies. You might find that the larger group naturally divides itself into smaller cliques. The solution would  either be to keep the head count between 4 and 5 people or to subdivide the project into smaller working pieces and assign subgroups from the larger group according to their strengths.
