Independent Estimates
Engaging an impartial outside party to collect and analyze data in order to forecast costs, schedules, or other project parameters.
Key Points
- Performed by a neutral third party separate from the project team and vendors.
- Provides an objective benchmark for costs, timelines, and other estimates.
- Helps spot unrealistic bids, overpricing, underestimation, or possible collusion.
- Supports negotiations, budgeting, and risk planning with evidence-based figures.
Example
A project manager planning a data center build hires an external cost consultant to develop a should-cost estimate for labor, equipment, and schedule duration. When supplier bids arrive, the team compares them to the independent estimate, identifies one bid that is 30% higher without clear justification, and uses the analysis to negotiate and adjust the procurement strategy.

- Parametric estimating by the internal team
- Three-point estimating

Correct Answer: C — Independent estimates
Explanation: Independent estimates use a neutral third party to develop objective benchmarks, which are ideal for validating vendor bids and identifying potential anomalies.
