Integrated Baseline Review(IBR)
A joint government-contractor review ensuring alignment among requirements, resources, and execution plans at the start of a contract.
Overview
An Integrated Baseline Review (IBR) is a formal joint assessment conducted by the government and contractor early in contract execution to verify that the performance measurement baseline accurately reflects the technical scope, schedule, and budget. It ensures both parties share a common understanding of the work to be performed.
Why It Matters in GovCon
IBRs are critical for large contracts with Earned Value Management requirements. A successful IBR establishes mutual confidence in the contractor's plan and provides a solid foundation for measuring progress. Poor baseline alignment discovered later can lead to costly re-planning and strained customer relationships.
Key Details
- Timing: Typically conducted within 180 days of contract award or within 60 days of establishing the PMB.
