A project manager is looking at the risk associated with the project schedule. Realizing that if the risks occur the project will be delivered to the stakeholders late, the project manager decides to consider the risk and promise delivery later than the most likely project completion date.

He then takes the time between the promise date and the most likely completion date and distributes it among the activities of the project schedule. This creates float in the schedule. This process is called:

a. Schedule delay.

b. Critical chain scheduling.

c. Buffering.

d. Contingency scheduling.
