Explanation
These three techniques are suitable for planning a schedule with limited information, as they allow the project manager to adjust the plan as more details become available. Iterations and reviews involve breaking down the project into smaller cycles of work, delivering value incrementally, and obtaining feedback from stakeholders.
Rolling wave planning and an adaptive approach involve planning the near-term work in detail and the distant work in broad terms, and revising the plan as the project progresses. Relative estimation involves comparing the size and complexity of tasks or deliverables to each other, rather than using absolute units of measure, and refining the estimates as more information is known.
