Project Buffer

In critical chain scheduling, a buffer placed at the end of the critical chain to protect the target finish date.

Definition

It aggregates the contingency removed from individual tasks; buffer penetration is tracked to signal schedule health.

Example

A 20-day project buffer is placed after the last critical chain task.

Exam tip

Project buffer protects the end date; feeding buffer protects the critical chain from feeding paths.
