Communication Calculation n(n-1)/2
I'm finding difficulities in calculation communication requirements. For example
1. 22 people are expected at your next stakeholder status meeting. Which of the following statements are true?
A. There are 242 lines of communication.
B. The number of attendees falls within the reasonable range for effective decision making.
C. There are 231 lines of communication.
D. There are too few people to make effective decisions
In some cases that we need to include the Project Manager and hence the answer is 242 otherwise it is 231.
I would appreciate if any one make me this clear that under which situation I should include Project Manager and skip.
