Quick Answer
The answer is bottom-up estimating, the most appropriate technique for achieving high cost accuracy at the work package level in a predictive project. This method delivers precision by decomposing work packages into smaller components, estimating each one individually, and then rolling up those estimates to form a total cost. Because it builds the budget from the ground up using detailed inputs from the team members doing the work, it minimizes the guesswork inherent in top-down or analogous approaches. On the Certified Associate in Project Management CAPM exam, this question tests your understanding of estimating accuracy hierarchy, often appearing alongside distractors like parametric or three-point estimating. A common trap is confusing bottom-up with analogous estimating, but remember: bottom-up is the most accurate because it uses the most granular detail. For a memory tip, think of building a LEGO castle—you count every single brick (work package) to get the true total cost, rather than guessing based on a similar castle.
This CAPM practice question tests your understanding of predictive plan-based methodologies. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
In a predictive project, the project manager needs to estimate the cost of each work package with a high level of accuracy. Which technique is most appropriate?
Bottom-up estimating
Correct: Estimates each work package individually for high accuracy.
Parametric estimating
Why wrong: Parametric uses statistical models; less accurate than bottom-up for detailed estimates.
Expert judgment
Why wrong: Expert judgment is subjective and not a standalone detailed estimating technique.
Three-point estimating
Why wrong: Three-point estimating provides a range, not single-point accuracy.
Answer choices
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
Bottom-up estimating provides the highest accuracy by estimating costs at the work package level and summing them.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Bottom-up estimating
Why this is correct
Correct: Estimates each work package individually for high accuracy.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
