I saw a good chart that explains the issues as teams grow by showing the lines of communication between team members as the size of the team grows.
If you draw a dot for each member of a team and then a line from each dot to each other dot, you can see the "lines of communication".
With 3 members, there are 3 lines of communication (loc)
4 members, 6 loc
6 members, 15 loc
10 members, 45 loc
14 members, 91 loc
Communication breaks down as more people are involved.

- alexpetralia 4y agoMetcalfe's law succinctly explains why communication becomes more fraught as teams and organizations grow. Good managers minimize this quadratically rising cost.
