What does adding buffer time to a project schedule typically achieve?

Adding buffer time to a project schedule enhances project flexibility and risk management by providing a cushion against uncertainties and unforeseen events that could potentially disrupt the project timeline. Buffers serve as a safeguard, allowing teams to absorb delays without significantly affecting the project's overall schedule. By incorporating buffer time, project managers can manage risks more effectively, ensuring that minor delays or interruptions do not lead to cascading effects that complicate the project further.

This practice also helps to account for variability in task durations, resource availability, and any other external factors that may arise during the course of the project. By doing so, the team retains increased control over the project flow and the ability to adapt to changes as they occur, ultimately improving the likelihood of on-time delivery and maintaining stakeholder satisfaction.
