Integrated Baseline Review (IBR)
Government Standards
Reviewed by forProject Technology - updated Sep 2026
Quick definition: An Integrated Baseline Review (IBR) is a joint government/contractor review held to confirm that a project's Performance Measurement Baseline (PMB) is realistic and complete.
During an IBR, the government and contractor jointly examine the PMB to confirm it captures the full scope of work, aligns with contract schedule requirements, and has adequate resources assigned. The review also checks that important risks have been identified and are being actively managed. It's typically held early in a contract or after a major re-baseline, not as a one-time formality at the end.
Why it matters
An IBR catches an unrealistic or incomplete baseline before performance measurement even begins, which is exactly when problems are cheapest to fix. Skipping this step risks measuring performance against a plan that was never achievable in the first place.

FAQ
Who takes part in an IBR?
Both the government (or customer) program team and the contractor's project team, including the Control Account Managers who own the detailed plans being reviewed.
Is an IBR a one-time event?
It's usually formally conducted once early in a contract, though the same validation thinking is often revisited after major re-baselines.
