A project baseline is crucial because it establishes the approved version of the project plan, which serves as a benchmark against which the project's progress and performance can be measured. This baseline typically includes key components such as the project's scope, schedule, and budget. By having an agreed-upon baseline, project managers and teams can objectively assess performance, identify variances, and make necessary adjustments to stay on track.

When any changes occur during the project, they must be evaluated against this baseline to ensure they align with the project's goals and objectives. This process allows for better management of expectations and outcomes, as all stakeholders have a common understanding of what the original plans entailed and how changes could affect the project’s trajectory. Thus, by serving as the measure of success and control, the baseline plays an essential role in effective project management.
