### Doubt on communication channel calculation

Hi,

I came across this question in one of the PMP practice sets.
Wanted to know the answer to this question. I thought that the answer must be 78, since there are 12 stakeholders + the project manager making n as 13. However, the solution mentioned that the answer is 66 by considering only 12 stakeholders.
Formula = n(n-1)/2

Am I missing something in my understanding here?

Thanks.

### Re: Doubt on communication channel calculation

Based on my observations (No standard rule as the language in questions is not always straight forward )

when
question asks how many channels project will have - Include PM
Question mentions - How many communication channels your team has - Exclude PM
Question mentions - X members including PM - Dont add PM to count
Question asks: How many channels will PM (Not project) have dont include PM

Again there is no standard rule, and challenge is when you have both answers in options, including and excluding PM in count.

Manish;
When you say "include PM"; you mean add 1 to the count? And when you say exclude you mean he is already part of the count and no need to add him separately?

Hi Manish,
But in above question there is no such clue whether to include or exclude PM while counting the factor "n"

How to tackle such questions ?

### Re: Doubt on communication channel calculation

You have five people working on your team, a sponsor within your company, and a client, all of
whom need to be kept informed of your project’s progress. How many lines of communication are
there?
A. 28
B. 21
C. 19
D. 31

Manish here both A and B are with PM and Without PM respectively...
it says You (1) have 5 people working on your team ...

I think we need to think like that when we have both anwers

This one is tricky I agree, at the start it says You have , however the question ask how many communication lines are there and not how many communications line do you have,
I would probably still not include PM based on the start of the question which says 'you have'

### Re: Doubt on communication channel calculation

I would go for A (21) as the question has Key Word Team . as per PMBOK team is inclusive of Project Manager , project management team & Project team members who work ,so in this particular question all inclusive 5

hence 5+1 sponcer +1 client.

Let me know my understanding is correct & answer to ?

I have spoken to different people regarding these doubts. I think when they mention sakeholders or project team that means the project manager is included and no need to add him to the count
