So what happens when a schedule change occurs? The project manager must ensure that the project schedule is updated to reflect the change, document the change, and follow the guidelines within the schedule management plan. Any formal processes, such as notifying stakeholders or management, should be followed.
Revisions are a special type of project schedule change that cause the project start date and, more likely, the project end date to be changed. They typically stem from project scope changes. Because of the additional work the new scope requires, additional time is needed to complete the project.
Schedule delays, for whatever reason, may be so drastic that the entire project has to be rebaselined. Rebaselining is a worst-case scenario and should only be used when adjusting for drastic, long delays. When rebaselining happens, all of the historical information up to the point of the rebaseline is eliminated. Schedule revision is the preferred, and most common, approach to changing the project end date.
EXAM TIP You only want to rebaseline in extreme, drastic scenarios.
