Hi Debra,
sorry I missed your message. Now I understand where my confusion came from: you were referring to the Exam Content Outline, while I had Table 1-4 in mind from the PMBOK Guide, referring to the processes grouped by Process Group and Knowledge Area. Of course there is a match between the two, but they provide a slightly different perspective. In fact, the way I looked at the Exam Content Outline is some sort of reference guide (a syllabus, if you will) of what you need to know in each of those five domains, in terms of knowledge and skills, and what we as PM are expected to do; at the end of your PMP exam you will receive an evaluation in each domain, detailed at the task level.
If you take (say) the stakeholder identification, this is part of Task 3 in Domain I; at the same time, the process that guides you through this "task" is the Identify Stakeholder process (13.1). Here you have a detailed list of inputs (i.e., what you need to perform this process); tools & techniques (i.e., how to perform this process); output (i.e., what this process brings as a result).
While the project charter is typically developed at the beginning of the project, the "Identify Stakeholders" process is performed periodically throughout the project. In this respect, it is not an "action item" that you tick once you are done with it, as you may need to go through this process again at different times while the project is ongoing.
Hope this clarifies a bit the difference between the two.
