In project planning, what are "lead times"?

Lead times refer to the period necessary to obtain materials and resources needed for a project before the actual construction or implementation can begin. This involves the time it takes to procure and deliver these materials to ensure that the project remains on schedule. Effective project planning requires careful consideration of lead times to avoid delays that may arise from waiting for essential items to arrive.

By understanding lead times, project managers can coordinate schedules, allocate resources effectively, and ensure that the workforce is not idled due to material shortages. This awareness also allows for better management of project timelines and overall efficiency, making procurement timing a critical component of successful project execution.
