I am having a doubt. PMBOK guide says that any of Project Management Plans or Project Documents need a change request and go through the 'Integrated Change Control' if an update is needed.
I took two simulator exams and in the explanation section of the result, it says you don't need a change request to update the Stakeholder register or Lessons learned register. Now, I am confused.
Do we need to submit a change request only for any of the project management plans? Project documents do not need a change request if they need an update??
