The team must create a schedule with limited information and is struggling to identify detailed tasks and estimate durations. Which three techniques should the project manager use? (Choose three.)

When detailed information is limited, rolling wave planning is effective because it allows for detailed planning of near-term work while planning future work at a higher level, adapting as more information becomes available. Relative estimation is useful when absolute estimates are difficult, as it compares tasks to a baseline task, providing a size or effort without requiring precise duration estimates. Iterations and reviews, characteristic of adaptive approaches, enable continuous feedback and adjustments, which are crucial when the project context is uncertain and requirements may evolve. A Gantt chart is a scheduling tool, not a planning technique for dealing with limited information. Bottom-up estimating requires a detailed WBS, which is precisely what the team lacks in this scenario.
