I am currently studying for the PMI PMP exam and stumbled upon the following question in Kim Heldman's "Project Management Professional Practice Tests" book (correct answer boldened):
A project manager performing Closing activities is currently focused on addressing the highest business value items first. What life cycle is she using to deliver her project?
A. Highly predictive
C. Highly adaptive
My answer was "adaptive" since "highly adaptive" meant nothing to me. I searched the PMBOK, 6th edition, and could not find any mention of "highly" adaptive vs. "adaptive", or "highly" predictive. Only "adaptive" and "predictive" are mentioned. Unfortunately, the answer in the book itself does not reference the PMBOK or Heldman's Study Guide.
Is this an occasion where the PMBOK differs from the actual PMP exam content, and the given answer can be considered correct, or should I disregard this question?
