Explanation

Rolling wave planning is a tool and technique in Define Activities because that process involves progressively elaborating work packages into schedulable activities - and rolling wave planning is exactly that mechanism: near-term work gets planned in detail while future work remains at a higher level until more information is available. Estimate Activity Durations (A) uses techniques like analogous, parametric, and three-point estimating to assign time values to already-defined activities, so rolling wave planning doesn't apply there. Develop Schedule (C) takes defined, sequenced, and estimated activities and builds the actual schedule model using tools like the critical path method - rolling wave planning feeds into it but isn't a technique within it. Sequence Activities (D) focuses on identifying dependencies between activities using tools like the Precedence Diagramming Method (PDM), not on how activities are progressively discovered.

Memory tip: Think of "Define" as the discovery process - you're deciding what activities exist, and rolling wave planning lets you define them in waves as the project unfolds. Wherever you're still figuring out what to do, that's where rolling wave planning lives.
