Mounir - I have a basic answer but, I'm glad I have not responded yet, because I would have missed part of a good responses.

Project Life Cycle (a more generic term) can contain process groups (which is a PMI standard)... what I have missed as most people do is the last portion of your statement, is that the Process Groups are designed to “repeat” in every phase of the Project Life-Cycle.

So I'm still reading before I respond...

Hi Mounir - thanks for your reply...

Can you expand on your statements, and include examples... Especially on the fact that process groups repeats in every phase.

The clear way you explained might the the base of my answer...
George

Why does your answer depend on mine?

By the way, my statements are not my invention. This is the PMBOK Guide

Much said here is correct. Let me add another perspective.

In my classes, I explain to students that a (pure) project manager is only doing the work as defined in the process groups, or in the now 49 PM processes. This work is iterative (except initiating and closing) and deliverables out of that are mainly progressively elaborated. (You could say agile by design).

On the other hand, the project team that is not involved in managing the project, the subject matter experts, are doing the work as defined by the life cycle and as sequenced by the phases. Which might be linear or iterative, or a mix called hybrid. They are in charge to develop the outcome or product of the project. The PMBoK does not say much about this, as it is specific to the project product, industry and environment. The PMBoK tries to cover project management, not product development.

In many companies, there are (not yet) pure project managers. Most working in project management are asked to be subject matter experts too. This means they not only have to understand the process groups but also the respective life cycle models and their content.

The PM work makes as a rule of thumb 10-15% of the total effort, the SME work accordingly 85-90%.
