PMI-ACP Question #630: Real Exam Question with Answer & Explanation

Question

Senior management is frustrated at the lack of a detailed implementation plan that shows exactly when the project will end and when all requirements will be met. The team has been using a rolling wave planning approach so far on the project. How should the agile practitioner explain to senior management the benefits of this approach?

Options

• AIt ensures a consistent level of details is available in the project schedule
• BIt prevents a wasteful buildup of requirements inventory that may never be processed
• CIt provides a concrete definition of project scope, cost and duration
• DIt allows the team to lock down the stories to be included in a release

Explanation

Rolling wave planning (also called progressive elaboration) deliberately plans near-term work in detail while keeping future work at a high level, updating the plan as more is known. The key benefit to communicate to management is that this prevents 'requirements inventory' waste - spending time and effort detailing requirements months in advance that may change, be de-prioritized, or never be built. Option A is incorrect because rolling wave intentionally maintains different levels of detail at different time horizons - consistent detail is not the goal. Option C is incorrect because rolling wave does not lock in scope, cost, or duration for the whole project. Option D is about locking down sprint stories, which is a different concept.
