John is in charge of a project that deals with laying out a lavish 18 hole golf course.The project work is in progress. He also has a number of contractors working on the project. Being an experienced manager, he knows that communication is key to success of the project. He has identified 10 stakeholders with whom he needs to communicate. Due to some internal and external organizational changes at the client end, three new stakeholders have been added with whom he needs to communicate with. He also had to reduce one of the contractors with whom he were communicating. How many communication channels does he has now?
Formula for determining number of communication channels is ((N)*(N-1))/2, with N being the number of stakeholders one needs to communicate with. In this example N=12 (10 plus 3 minus 1), which makes the correct answer option D.
it is good to always state the source of your questions to give credit to the question creator.
Including the PM in communication channels questions is always the trick in similar questions.
as illustrated the answer is B as the people involved in communication including the PM is 13 (channels = 13*12/2 = 78).
In this particular instance I would NOT count the PM because the question reads
How many communication channels does he has now?
So my interpretation is that the question is asking "how many does he personally have?"
I would, however, count the PM if the question where to read
How many communication channels are there on the project now?
In the end, I consider this to a "bad" PMP Exam Sample question because it contains so much ambiguity and there is no real way of determining what the correct way of doing it is. If this question were part of our simulator question pool, then we would probably remove it because it's "so bad".

Sir, as we know, according to PMBOK, PM is the process owner in case of communication management. So when question of communication channel arises, he needs to consider overall count not his personal count. e.g. if PM has 3 members in his team, according to your logic, number of communication channel is 3. However, according to my understanding, it'll be 6. Similarly PM identified 10 stakeholders means, total stakeholders 11, PM is also stakeholder. Here, "how many channels PM has" - doesn't imply how many he personally has, it's question of whole project only. Please clarify, if I'm wrong.
