Question 1 of 6
A project with 8 stakeholders is expanded to include 5 more stakeholders. How many additional communication channels does this add, and what is the new total?
- A.45 additional channels; 91 total
- B.The number of channels increases linearly, not combinatorially
- C.55 additional channels; 83 total
- D.50 additional channels; 78 total
Show answer and explanation
Correct answer: D
Communication channels are calculated as n(n-1)/2. With 8 stakeholders there are 8x7/2 = 28 channels. With 13 stakeholders there are 13x12/2 = 78 channels. That means 50 additional channels are created. This illustrates how communication complexity grows rapidly as stakeholders are added.
