PMP Braindump Chart Construction Process
by Dean Giles

We found this nice article from Dean Giles of PMExamReady.com that explains the PMP braindump process based on the brain dump sheet table on Page 43 of the PMBOK Guide V4. It visually shows the relationship between the Project Management Process Groups and the Project Management knowledge areas. This is really helpful. I encourage you to read it.

Why do we need the communications channels formula?
The communications channels formula is N * (N-1) / 2. It is a way to numerically show the importance of proper communications management on a project. We all have a "gut feeling" in regards to this and most people would agree that "the larger the project, the more communications becomes a challenge".

The communications channel formula is a way to express this "challenge" numerically.

First of all, it expresses that the number of people on the project is at the heart of what makes communications a challenge. It's not the size of the budget or the the technical complexity that poses our greatest communications challenge. It is the number of people with whom we need to communicate about our budget and technology that makes it harder, the more people we involve.

Second, the formula acknowledges, that it is not only us (the project manager) who has to communicate. The formula takes into account that on a 5 people team it is not just me who is communicating with 4 others, but it's everyone talking to everyone. The number of people who are constantly communicating with each other is much larger than that.

This second point highlights 2 facts: 1.) Harold Kerzner's figure that a project manager spends 90% of her/his time communicating suddenly makes a lot more sense. 2.) It is impossible for us to try and manage all the various conversations that will be going on between the members of our project team.

Third and last, I use the communications channels formula as a "teaching tool". Both in a classroom and an office environment. In the classroom this is simply the formula that you have to know for your PMP Exam. There is a very high likelihood that one of the 200 questions on your exam will include this question. Second being able to discuss this formula with the project sponsor and project team on an actual project allows me to highlight why we cannot just simply "do" communications. We have to plan the how, what, when, why and with whom we communicate early on in the project, so that communications will be effective and efficient.

Sample PMP Exam Question
Joe is working as a project manager in a highway construction project. He wants to use a fixed price contract instead of cost-plus contract. The risk response strategy he is using in this case is an example of?

A.) Risk Avoidance
B.) Risk Transference
C.) Risk Mitigation
D.) Risk Acceptance

Hint: The project manager in this example is currently performing the Conduct Procurements process but the answer is in the Plan Risk Responses process.
