What method is used to allot more time in a project schedule to account for unforeseen delays?

The method used to allot more time in a project schedule to account for unforeseen delays is known as contingency. Contingency involves setting aside extra time within the project timeline to accommodate potential risks or unexpected events that could impact project progress. This approach allows project managers to handle uncertainties effectively without significantly impacting the overall schedule.

When planning a project, it is vital to foresee obstacles such as weather delays, resource availability, or changes in project scope, which may arise during execution. By including a contingency allowance, you create a buffer period that can absorb these delays, ensuring the project can still meet its final deadlines or deliverables.

Buffering, while it may seem related, typically refers to adding extra time to specific tasks within a schedule rather than providing an overall additional time allocation for potential delays. Scheduling is the process of creating a detailed plan of action and does not inherently involve risk management. Time-framing refers more to establishing the start and end points of a project rather than addressing unpredicted delays, which distinguishes it from the concept of contingency.
