In accordance with the PMBOK® Guide (Project Schedule Management), specifically within the Define Activities process, Rolling Wave Planning is a form of progressive elaboration where the work to be accomplished in the near term is planned in detail, while the work in the future is planned at a higher level.

Function: This technique allows for work to exist at various levels of detail depending on its position in the project life cycle. During early strategic planning, when information is less defined, work packages may be decomposed only to a certain level. As the project progresses and more information becomes available, those high-level components are decomposed into detailed activities.

Application: It is particularly useful in projects with high levels of uncertainty or those using an adaptive (agile) or hybrid life cycle, where the final product is not fully defined at the start.

Relationship to WBS: While the WBS provides the structural framework, Rolling Wave Planning is the specific scheduling technique used to manage the timing of that detail ' s emergence.

Analysis of Distractors:

A. Historical relationships: This is a tool/technique used in Estimate Activity Durations or Estimate Costs (Parametric Estimating) to predict future results based on past data. It does not dictate the level of detail in the plan based on the life cycle.

B. Dependency determination: This is used in the Sequence Activities process to define the relationship between tasks (e.g., Mandatory, Discretionary, External, or Internal). It determines the order of work, not the level of detail.

C. Bottom-up estimating: This is a technique for estimating duration or cost by aggregating the estimates of lower-level components. It requires a high level of detail to be present before the estimate can be made, rather than allowing for various levels of detail.
