A project manager is developing the project management plan. The sponsor requests detailed cost estimates for each work package, but the activities have not yet been defined. What should the project manager do?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Defer the cost estimates until after activity definition.
Detailed cost estimates require that activities are defined first, as per the typical planning process sequence (e.g., PMBOK). Without activity definition, the project manager cannot accurately estimate costs for each work package. Option A is wrong because analogous estimating provides rough estimates, not detailed ones, and is used when little information is available—not suitable for this scenario. Option B is wrong because a rough order of magnitude estimate is not detailed and does not meet the sponsor's request for detailed cost estimates. Option D is wrong because breaking down work packages into activities is part of activity definition, which has not yet been done; bottom-up estimates should follow activity definition, not precede it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use analogous estimating to provide rough estimates.
Why it's wrong here
Analogous estimating gives rough estimates, not the detailed estimates requested by the sponsor.
- ✗
Ask the sponsor to approve a rough order of magnitude estimate.
Why it's wrong here
A rough order of magnitude estimate is not detailed, and the sponsor requested detailed estimates.
- ✓
Defer the cost estimates until after activity definition.
Why this is correct
Activity definition must precede detailed cost estimation to ensure accuracy.
- ✗
Break down the work packages into activities and create bottom-up estimates.
Why it's wrong here
This is premature because activity definition has not yet been done; bottom-up estimates require defined activities.
