The Resource Buffer is a resource that is keptĪlongside the critical chain to ensure continuity of the work.įor the PMP exam, it is sufficient to know that the critical chain method is a resource optimized diagram and uses buffers. The Feeding Buffer is added to the non-criticalĬhain so any activities that get delayed will use the feeding buffer. Any activities which are delayed will eat up this buffer. The Project Buffer is added at the end of the In the critical chain method, instead of the term “float” the term On this technique, as this is a schedule network diagram technique.

Please note that in the sixth edition of the PMBOK Guide you However, including resource availability increases the duration of the project. In the critical chain method, the critical path is optimized based on resource availability, which increases the chances of completing the project in the estimated time.

Therefore, the critical path method was upgraded to remove these drawbacks and named the critical chain method. These miscalculations affect the schedule. Moreover, since the duration of the critical path is the duration of the project, project managers tend to inflate the duration of activities on a critical path to keep an extra margin for completing the project. The chances of completing the project within the schedule are low.It assumes an unlimited supply of resources.
