# TOPIC: Number of Communication Channels

## Number of Communication Channels 11 months 3 weeks ago #30647

 Cosmin Ionescu Topic Author Offline Fresh Boarder Posts: 3 Thank you received: 0 Hello, I am curious as to the approprite calculation of the number of channels when asked how many channels exist in a given scenario that include a variety of stakeholders but specifically leaves out the PM. 1. When being provided with the stakeholders for which the calculation of the number of channels is asked, and the PM and/or keyword "project team" is not included in the question, how would one best address summing up the number of stakeholders to produce the value "N" which would be used in the calculation: # of communication channels = [N(N-1)]/2? Should the PM be counted in the value of "N" anyway? 2. Furthermore, if the question states that you are the PM and are given some stakeholders to count towards the calculation of "N", would this be the case to include yourself as the PM in the calculation for the value of "N"? Follow-up to the question above, if the question asks how many communication channels do you have as the PM, should you include yourself in the count and if yes/no, why? 3. Are there circumstances in which one would not include the PM in the calculation for "N"? 4. Lastly, I would like to thank you for providing us with the PM Prepcast Exam Formula Study Guide as it was useful in understanding the equations better. May I take a moment to recommend some of the above questions to be included and addressed within the aforementioned document? I understand that going through every possible scenario would be time-consuming, however, if the Prepcast team would be so kind as to answer these questions it would be greatly appreciated.

 Brad Pennington, PMP Offline Senior Boarder Posts: 44 Karma: 5 Thank you received: 6 Cosmin, I'll agree with Kyle on this one. If the exam mentions the PM in the problem statement, then count the PM as a part of N, and vice versa. Remember that the PM is, by definition, one of the stakeholders on the project, so it would make sense to include him/her in the N calculation. All of that said, any question you see on the exam requiring you to use a formula will be very straightforward. The formula-based questions are checking that you know how to use the formula in question; they aren't trying to trick you. Best of luck on your exam!

 Cosmin Ionescu Topic Author Offline Fresh Boarder Posts: 3 Thank you received: 0 Hello Brad, thank you for sharing your thoughts on my questions. I figured it made sense to always include the PM in the value of N when asked about the total number of communication channels. Your e-mail address will never be displayed on the site.
