- The formula for communication channels is: N x (N - 1) / 2, where N is the number of team members. With 10 members: 10 x (10 - 1) / 2 = 10 x 9 / 2 = 45 channels. This formula demonstrates why communication complexity grows rapidly as team size increases. Adding just one more member (to 11) would create 55 channels, an increase of 10 new channels.
