What is the function of the Lag field in task dependencies?

The Lag field in task dependencies is essential for managing the timing of related tasks within a project. It specifically allows project managers to specify delays or advancements that occur between dependent tasks. For instance, if a task must start a few days after its predecessor completes, a lag can be added to reflect that necessary wait time. Conversely, if there is an opportunity to begin a subsequent task before the previous one has fully completed, leading to an overlap, the lag can be adjusted accordingly.

This functionality is crucial for accurate project scheduling, as it helps in tracking how delays or advancements in one task can affect subsequent tasks, ensuring that the project timeline remains realistic and achievable. This feature directly impacts resource allocation, task prioritization, and overall project management efficiency, which underscores its importance in handling task relationships effectively.
