CAPM Practice: Demonstrate an understanding of a project management plan schedule

Rolling wave planning is a form of progressive elaboration used even within predictive projects. Work packages that are near in time are planned in detail. Work packages far in the future are planned at a high level until more information becomes available. This pragmatic approach acknowledges that detailed planning for distant future work is less valuable when conditions may change.

**Why not A:** Rolling wave planning does not change the project scope every few weeks. The overall scope remains defined; only the level of planning detail changes as work packages move from distant future to near term. Scope changes still require formal change control.

**Why not C:** Rolling over a plan from a previous project describes analogous planning or template reuse, not rolling wave planning. Rolling wave planning is about progressively elaborating the current project's plan as more information becomes available over time.

**Why not D:** Rolling wave planning is not the same as agile sprints. It can be used within a predictive project to manage planning detail levels without adopting iterative delivery. The project still follows a sequential approach; the planning simply becomes more detailed as work approaches.
