Exam PMP topic 1 question 1046 discussion

Its question about cost, D seems to be the answer.

D. Used bottom-up estimating

If details were missing, a more thorough estimate should have been used and that would be bottom-up, which examines the work at the most granular level of detail.

please stop using chatGPT, bottom-up is using when we have details cost, does it mentioned in the question? the question is audit team thinks that something is missing, analogous estimation uses historical data from a similar activity or project

Bottom-up estimating involves estimating the cost or duration of individual work items and then aggregating them to get an overall project estimate. This approach is more detailed and accurate compared to analogous estimating, especially when there might be missing details in the estimates. By breaking down the project into smaller components and estimating each one separately, a more accurate and reliable cost estimate can be obtained. This method is particularly useful when there is uncertainty or complexity in the project. Utilizing three-point estimates and including lessons learned from past projects can also contribute to better estimating accuracy.

B. Validated the schedule performance index (SPI) to evaluate deviation
