How big should virtual teams be?
Participants on our remote and virtual teams training often ask how big should virtual teams be for maximum effectiveness.
At one level the answer to team size is “as big as it needs to be to deliver its purpose”. If you have a complex global team on a major project then you may need 20 or (many) more people. But we also know that the right team size size for a team in terms of effective human dynamics, decision making and maintenance of relationships is much smaller than that.
- Studies in business schools have found that an effective face to face syndicate team size is no more than 4-6 people.
- A recent Times article found that a group of 8 was the worst number of people for making decisions and that voting rather than consensus was essential for groups of 20 or more.
Both of these studies focused on the right team size for face to face groups.
In our book Speed Lead we identify two factors that drive down effective team size in complex organizations
- Interdependence – if we really need to communicate and coordinate intensively (true or what we call “spaghetti” team work) then we can only maintain a limited number of connections. (a team size of 6 people creates 15 interconnections, 20 people create 190 interconnections). Star group (hub and spoke) structures can be organized to work well with larger numbers of people
- working through technology – conference calls and other technologies limit effective contribution and discussion. If you ever attended a conference calls of 20 people you will know it soon descends into a series of monologues.
Because of this we recommend an effective team size of 4-6 for real spaghetti teamwork. If you need 20 people for a global team or project try to cluster them into several smaller sub-teams based on common objectives, geography, interdependence etc…
The average team size from our speed survey is 12 and people tell us they are part of 5 teams. This means that people are managing an average of 330 interdependent relationships. This would allow abut 7 minutes per week per relationship!
This reinforces our view that most “teams” are not really engaged in interdependent spaghetti team work but are actually groups of individuals engaged in largely independent tasks with a small amount of teamwork.
