How is progressive elaboration different from rolling wave planning?
Progressive elaboration is the opposite of rolling wave planning.
Progressive elaboration is not detailed or accurate.
Rolling wave planning is a theoretical exercise.
They are similar. Rolling wave planning is a form of progressive elaboration where details are planned for work closer to the present time. Details for future work is planned out only at a high level.
Both are two aspects of iteration in planning processes. Progressive elaboration involves continuously improving and detailing a plan as more specific, detailed and accurate information becomes available over time. Rolling wave planning is a form of progressive elaboration where the work to be accomplished in the near term is planned in detail at a low level but future work is planned only at a high level. The details are fleshed out later.
