PK0-005 Practice Question: During project planning, the project manager…
During project planning, the project manager needs to estimate the cost of each work package. Which tool or technique is best suited for this?
⚠ Common exam trap
Many exam-takers confuse bottom-up estimating with parametric estimating, assuming that parametric methods are always more precise, but the question specifically asks for the technique best suited for estimating each individual work package, where bottom-up's granular decomposition is key.

Why each option matters
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 is best suited for estimating the cost of each work package because it involves decomposing the work package into its lowest-level components (activities or tasks) and estimating each one individually. This provides a high level of accuracy by aggregating detailed estimates from the team members who will perform the work, making it ideal for project planning when detailed scope definition is available.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Parametric estimating
Why it's wrong here
Parametric estimating uses unit rates, but bottom-up is more detailed for work packages.
- ✓
Bottom-up estimating
Why this is correct
Bottom-up estimating calculates costs for each work package, then sums them.
- ✗
Three-point estimating
Why it's wrong here
Three-point estimating uses ranges, not directly estimating each work package.
- ✗
Analogous estimating
Why it's wrong here
Analogous estimating uses similar past projects, less accurate for detailed planning.
