Exercise 10

Schwalbe P.420 - Chapter 10, Ex 3

How many different communications channels does a project team with six people have? How many more communications channels would there be if the team grew to ten people?


According to Schwalbe,
number of communications channels = n(n-1)/2

So, if there are 6 people in the team, it will have 6(6-1)/2 = 15 channels;

When the team grew to have 10 people, there will have 10(10-1)/2 = 45 channels, which means there will be 45-15 = 30 channels more in compared to a 6 people team.
