Buffertperioder

Buffertperioder, often translated as buffer periods or contingency periods, are designated intervals of time intentionally added to project schedules. Their primary purpose is to absorb unforeseen delays or disruptions that may occur during the execution of a project. By incorporating buffer periods, project managers aim to protect the project's critical path and ensure that the overall project deadline is met.

These periods are not typically allocated to specific tasks but rather act as a safety margin for the entire project or significant phases within it. They can be strategically placed at the end of a project, at the end of major project phases, or even within critical tasks that are known to have a higher degree of uncertainty. The size of a buffer period is determined by various factors, including the complexity of the project, the reliability of estimates, the experience of the team, and the potential for external risks.

The effective management of buffer periods is crucial. If not utilized properly, they can be consumed by non-critical activities, rendering them ineffective when genuine delays occur. Conversely, if buffers are too large, they can lead to inefficiencies and an inflated project timeline. Methodologies like the Critical Chain Project Management (CCPM) place a strong emphasis on buffer management, advocating for the consolidation of individual task buffers into a single project buffer. This approach aims to improve visibility and control over the buffer's consumption.
