Hi @tim jerome >> For the scenario below, I assumed the PM had to be added so the total number jumped from 6 to 11 stakeholders and the team is not listed so I selected A since 40 was not an answer choice. Thank you very much. You are the project manager for the ABC Project. Initially, you identified 5 stakeholders for your project. As the project moved ahead, 5 more stakeholders got involved in the project. Assuming that they all need to communicate with each other, how many additional communication channels should be there? A. Depends on the number of project team members B. 5 C. 45 D. 35 Correct Option Explanation Using the formula N(N-1)/2, where N represents the number of stakeholders, there are 35 communication channels. Initially there were 5 stakeholders which made 10 channels. An addition of 5 more members means the team has 10 members and 45 channels. Therefore, the additional communication channels are 45-10=35.
