The correct choice is bottom-up estimating when the sponsor needs improved cost estimate accuracy. This technique achieves the highest precision by breaking down the project into individual work packages and estimating each one in detail, often using the work breakdown structure as a foundation. Unlike analogous estimating, which relies on historical data from similar projects and carries significant uncertainty, bottom-up estimating accounts for the unique specifics of every task, making it ideal when detailed information is available. On the Certified Associate in Project Management CAPM exam, this question tests your understanding of estimating accuracy hierarchy, where bottom-up is the most accurate but also the most time-consuming. A common trap is selecting parametric estimating, which is also accurate but relies on statistical relationships rather than granular task analysis. Remember the memory tip: “Bottom-up builds accuracy from the ground up,” contrasting with top-down methods like analogous that sacrifice precision for speed.
CAPM Practice Question: Project Management Fundamentals and Core Concepts
This CAPM practice question tests your understanding of project management fundamentals and core concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
The sponsor is concerned about the accuracy of cost estimates prepared using analogous estimating. Which estimating technique should the project manager recommend to improve accuracy?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Bottom-up estimating
Option C is correct because bottom-up estimating involves detailed analysis of each work package, providing the highest accuracy. Parametric is also accurate but bottom-up is more precise when detailed information is available.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Reserve analysis
Why it's wrong here
Reserve analysis adds contingency, but does not improve the base estimate accuracy.
✓
Bottom-up estimating
Why this is correct
Bottom-up estimating uses detailed cost data from individual work packages, offering the highest accuracy.

Read the scenario before looking for a memorised answer.
✗
Parametric estimating
Why it's wrong here
Parametric is a statistical method but may not be as detailed as bottom-up for accuracy.
✗
Three-point estimating
Why it's wrong here
Three-point estimating improves accuracy with ranges but still relies on estimates of individual activities.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CAPM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Variation 1. Which THREE are techniques used for estimating activity durations?
hard
✓ A.Three-point estimating
✓ B.Parametric estimating
C.Reserve analysis
D.Monte Carlo simulation
✓ E.Analogous estimating
Why A: Analogous (A), parametric (B), and three-point (C) are all estimating techniques. Reserve analysis (D) is used for contingency reserves, not duration estimation. Monte Carlo simulation (E) is a risk analysis technique.
