Integrated Baseline Review (IBR) White Paper

Return to Resources

Page 2 - What Is the Purpose of an IBR?

An IBR is a joint assessment conducted by the Customer Program Manager and the contractor to verify the realism and accuracy of the PMB.  This involves verifying the technical content of the baseline and assessing the realism and accuracy of the related resources (performance budget and IMS).   The IBR is unlike the Validation Review that focuses on EVMS compliance with ANSI/EIA-748.  Instead the IBR focuses on assessing the realism of the program baseline. The IBR confirms the program baseline by making sure that all work is defined, scheduled and budgeted.

Any completed work is reviewed to insure that the performance taken was collected and measured correctly.  That the methods used to determine performance were consistent and used objective metrics.

The latest revised estimate to complete (ETC) is reviewed for correctness.  A review of the documented ETC process is made to insure that there are established processes in place.  In addition, the thresholds for performing ETCs are reviewed to determine when and where ETCs are performed.  How often are program ETCs done, at what point does a CAM perform an ETC on his effort. These thresholds can be time related, schedule cost index or as a plus or minus percent change of the EAC.

All program related cost, schedule, technical, resource, etc. risks are identified and their mitigations are reviewed.

All Earned Value Management System (EVMS) documentation will be reviewed for its accuracy and compliance with ANSI 748. The use and understanding of all existing EVMS documentation will be reviewed during the CAM interview process.
