So...not more Knowledge areas??

Nohely, I share your confusion.

The 'PMI approach' seems to me a bit more fuzzy with ed7 and ed6 still recommended by some. PMPs should learn along ECO, now different from both, not helpful. Also isolated offerings for starting with PM like Kickoff or PM Ready (by PMIEF) seem not be fully aligned with either PMBoK edition nor the ECO. DA comes on top with its own approach. Also the 3 upcoming construction certs do.

So, I conclude there is no single PMI approach for projects anymore. And - yes - I am still struggling what to show to my students. One option is the PMP ATP course deck, which is not available publicly.

Which part of v6 do you use as the base of organizational PM methods, today?

I brought up that there is a difference between phases and process groups because you asked the question, "...don't we start, plan, execute, and close?" We do, and this hasn't changed.

I'm glad you brought up tailoring. The following information, from v7, is similar to information contained in v6.
_____
In the Glossary, p. 245 - "Project Life Cycle. The series of phases that a project passes through from its start to completion."

Deciding on a life cycle and the phases of the life cycle is an example of tailoring. p.134

Section 3.5, Tailoring the Performance Domains, begins on page 145. On page 148, in 3.5.3, Development Approach and Life Cycle, the following questions are presented as questions you should ask when tailoring a project life cycle.

- What is an appropriate life cycle for this specific project?
- What phases should comprise the project life cycle?

On page 170, 4.2.7.4 Process Groups, "Groups of processes are not project phases. The Process Groups interact within each phase of a project life cycle. It is possible that all of these processes could occur within a single phase. Processes may be iterated within a phase or life cycle."
_____

Both versions emphasize life cycles. Neither version defines which phases a project should have. In both versions, you define the life cycle, the phases, and when to start, plan, execute, and close the project.

So, yes, I think v7 can be used as a foundation in the same sense as v6. A foundation is something you build upon, not the definitive source of all things project management. That being said, I have not compared both versions to identify what is "not" in v7 that was in v6. If there is something in v6 that you need, I doubt PMI would have a problem with using it.

Thank you Aaron for taking the time to detail the key pages and sections of guide 7. I have re-read them, I got your point.

"Both versions emphasize life cycles. Neither version defines which phases a project should have. In both versions, you define the life cycle, the phases, and when to start, plan, execute, and close the project"

I have no confusion between the projet phases, or PLC, or process group. Its pretty clear to me.

What probably scare me its using two guides and sure three (agile guide) . Especially when you have to create material to teach new leaders, directors, or digital project managers.
...new times..new waves!
Thanks again, keep in touch!
I would like to continue sharing experiences in the use of v7.

Thomas, I really apreciatte your shared points. thank you!!
