Project Management Professional (PMP) Exam Practice – Question1821

As you use the critical chain method in lieu of the critical path method in developing your schedule, assume you have determined the buffer schedule activities. Your planned activities are scheduled to their latest possible planed start and end dates. Therefore, you
are focusing on______________


A. Managing the free float of each network path
B. Managing the total float of the network paths
C. Managing remaining buffer durations against the remaining durations of task chains
D. Managing the total buffer durations against the durations of the task chains

Correct Answer: C

Explanation:

Explanation:
The purpose of the critical chain method is to modify the project schedule to account for limited resources. The schedule is built using duration estimates with required dependencies and defined constraints as inputs. Then, the critical path is calculated and
resource availability is entered, which means there is a resource-limited schedule with an altered critical path. Buffers protect the critical chain from slippage, and the size of each buffer accounts for the uncertainty in the duration of the chain of dependent tasks
that lead up to the buffer. This method then focuses on managing the remaining buffer durations against the remaining duration of task chains.
