In August of 2021, PMI released the PMBOK 7th Ediiton. I have a previous post describing what's new. Surprisingly, is a book filled with professional soft-skills, and not really a process-guide for executing projects. Wihile PMBOK 1-6 Editions contain step-by-step process guidance for project execution, PMBOK 7 is all about the soft skills.
I tell my PMP and CAPM students they will need both, and an easy way to think about it is to use PMBOK 6 for learning how to manage projects, and PMBOK 7 for learning how to be an excellent project manager. One analogy I used in a recent public presentation is that PMBOK 6 is the bones, and PMBOK 7 is the meat.
