119.4 Setting Schedule Baseline and Baseline Modifications
Project Managers shall work with the project core team members to establish tasks needed for the delivery of the project and the realistic task durations of time expected to start and complete each task.
When all tasks and realistic completion durations are established, the project manager shall set the project baseline 0 for project reporting and baseline 1 for a historical schedule record.
In the event a schedule must change significantly enough such that the letting date must move, the project manager shall modify all tasks and durations to establish the new project schedule and re-baseline the project as baseline 0 for reporting and baseline 2 for the next historical schedule record. If needed, the schedule may continue to be re-baselined as baseline 0 and baseline 2,3,4 etc.
