CAN'T BE 'B', because rolling phase implies there are details available in the near term, which contradicts to the question.

BCD is correct.

The project manager should use the following three techniques: 1. **B. Rolling wave planning and an adaptive approach**: This technique involves planning in waves as the project unfolds and more information becomes available. This can be particularly useful when dealing with limited information. 2. **C. Relative estimation to determine the task or deliverable sizes**: Relative estimation involves comparing tasks to each other to determine their relative sizes. This can be a useful technique when detailed task information is not available. 3. **D. Iterations and reviews to continuously keep adapting the plan**: This involves regularly reviewing and updating the plan as the project progresses and more information becomes available. This can help ensure that the plan remains relevant and effective, even when starting with limited information.

The three techniques that the project manager should use in this scenario are: B. Rolling wave planning and an adaptive approach. C. Relative estimation to determine the task or deliverable sizes. D. Iterations and reviews to continuously keep adapting the plan.

BCD is correct. No details means you cannot have Gantt chart (A), nor bottom up (E).

BCD es correcto

BCD is correct. No details means you cannot have Gantt chart (A), nor bottom up (E).

Rolling wave planning, as part of an adaptive approach, allows the project team to plan and schedule work based on the information currently available, understanding that further details will be defined as the project progresses. This is especially useful when there's limited information at the outset. Relative estimation, often used in agile methodologies, helps the team determine the size or complexity of tasks or deliverables in relation to one another, rather than trying to pin down exact durations without sufficient detail. This method is beneficial when precise estimations are challenging due to uncertainties. Lastly, using iterations and reviews provides a structured framework for the team to regularly revisit and adapt the plan based on actual progress and emerging information. This iterative process ensures the project remains aligned with objectives and can adjust to any changes or newly recognized requirements.

Ans: BCD. E is completely out of picture for this scenario.

B ,C and D ..Correct answer A and E cannot be used since no completed information is available detailed tasks to be carried out during the project

B. Rolling wave planning and an adaptive approach: Rolling wave planning involves planning for the near term in detail while keeping the long-term planning at a higher level. It's an adaptive approach that allows for adjustments as more information becomes available. D. Iterations and reviews to continuously keep adapting the plan: Using iterative planning and conducting regular reviews allows the project team to adapt the plan as more information becomes available and as the project progresses. It helps in refining the schedule over time. E. Bottom-up estimating based on a work breakdown structure (WBS): Bottom-up estimating involves breaking down the project work into smaller, detailed tasks and estimating the duration and effort for each task. It provides a more accurate estimate when detailed information is available. So, the correct answer for the PMP exam would be B, D, and E. These techniques align with best practices for schedule planning and adaptation in situations with limited information.

The question clearly says that "The team is having issues identifying the detailed tasks". so gantt chart can't be used as detail tasks are not available. Best suitable options are B, C & D

correct answer
