What does the term "lead" mean in project scheduling?

In project scheduling, the term "lead" refers specifically to the ability to start a dependent task before its preceding task has been completed. This technique is often utilized to optimize the schedule by overlapping tasks, which can expedite project completion. For instance, if Task B is dependent on Task A, applying lead time would allow Task B to commence even while Task A is still underway, thus enhancing efficiency and potentially reducing the overall duration of the project.

This concept is crucial in project management because it enables the effective use of resources and time, allowing for more flexible scheduling and management of critical path elements. Understanding how lead can be effectively employed helps project managers create realistic timelines and keep projects on track by maximizing workflow continuity.
