Integrated Baseline
Definition
The Integrated Baseline (also called the Performance Measurement Baseline, PMB) is the approved combination of scope baseline + schedule baseline + cost baseline. It is the foundation for project performance measurement using Earned Value Management (EVM). Changes to any baseline require formal change control. Management reserve sits outside the PMB and is not part of performance measurement — it requires sponsor or CCB authorization to use.

Exam angle
- PMB composition: scope + schedule + cost baselines ONLY — management reserve is NOT part of the PMB; contingency reserve IS included in the cost baseline
- Baseline vs. plan: the baseline is the approved snapshot requiring change control; working estimates can be updated without formal change control
- EVM requires a baseline: you cannot calculate SV, CV, SPI, or CPI without the PMB — scenarios asking about performance measurement imply an established baseline
