In projects where there is a gap between the real business requirements and the stated business requirements, agile methods are extremely helpful. Agile methods provide a solution to this problem by:
- A. Purposefully building and reviewing prototypes and release versions to refine requirements.
- B. Replacing the project manager with a Scrum master in order to expedite the project.
- C. Completing the project quickly so that gap is significantly reduced.
- D. Eliminating the documentation altogether from the project management approach.

Correct Answer is A.
Agile methods purposefully build and review prototypes and release versions in order to refine the requirements. As a result, scope is defined and redefined throughout the project. PMBOK 6th edition, Page 133.
