Hi there,
I would attempt replying to your questions one by one. I would like to tell you in advance that I am still a PMP aspirant.
Question 1: A project is divided into phases. After completion of one phase and before entering into next phase, what you need to perform? Create project charter or create project management plan. My understanding is project management plan. Let me know if you agree/disagree with the choice.
Answer: Each phase of a project is considered as an individual project in itself. We need to develop project charter in the initiation phase of each project phase. The project management plan is an output of the Develop Project Management Plan process in the Project Integration Management Knowledge area. It is created and updated progressively throughout the project.
Question 2: In closing process, it needs to make sure that all requirement has been met. My questions is if it is found that one/some of the requirement is not met, how that will be addressed? Is there any possibility that a change request will be issued to handle this variance?
Answer: If a requirement is not met, then Project Manager should communicate it to the project team and customer before closing. Based on the discussion and approval from key stakeholders, either that requirement has to be executed in the given phase or moved to the next phase. If it moves to the next phase then it should be documented as an approved changed request.
Question 3: There is a approved change request. The baseline(s) and project management plan needs to be updated. Under which process they will be updated? Direct & manage work or Monitor and control work. My understanding is Monitor and control process is the right choice.
Answer: Yes, I think 'Monitoring & Controlling' is the right choice.
