And you need to consider all the entities that get impacted by the project and participate in the communication. Also is there a need to consider Project team members? The answer is yes you need to consider whoever allowed communicating with the group. Then while putting the value of n, the test taker starts wondering – does he need to consider Project Manager too. This statement makes a PMP® exam aspirant think that in this calculation he needs to consider stakeholders. For example, a project with 10 stakeholders has 10 (10 – 1) /2 = 45 likely communication channels” In this blog, I will address all these confusions.Īs per the PMBOK® Guide, The total number of likely communication channels is n (n – 1) /2, where n signifies the number of stakeholders. Some part of the confusion attributed to the way PMBOK® Guide defines the value of n and the way practice test puts the case in front of PMP® exam aspirants. But I noticed, the number of questions from PMP® exam aspirants popping in our Forum ‘how to calculate communication channels.’ The confusion surrounded by what the value of ‘n’ is. A simple formula n (n-1) /2 can do it for you. If there are six members in the team, the number of communication channels rise to 15 (6*5/2)Įarlier I was thinking, calculating communication channels does not seem like a question that needs an entire blog for an answer. Communication complexity increases as the number of people increases in a project. It shows that communication complexity is much larger than the number of members in the project. It includes 6 (n (n-1)/2) channels by which these four members are communicating with others. Say, there are four members in a team: then communication complexity is not about one person is talking to others. Knowing the number of people in the project brings awareness about communication complexity. Now the question is how to discover your project communication complexity? The answer lies in the number of people who are communicating with each other. And, increasing communication complexity is a major obstacle to ineffective communication. In this business, effective communication is the most important success factor. Whether you lead a project, own the product delivery, or involved as a subject matter expert, you are all in the communication business.
