Supplier Lead Time is the amount of time a manufacturer needs to produce and deliver products or services to buyers. It is the sum of three distinct factors: the processing time, order quantity and lead-time given by the suppliers. Understanding this timeline is essential for accurate supply chain management. Being armed with up-to-date supplier lead times helps manufacturers plan ahead and guarantee on-time delivery. At its core, supplier lead time is an important facet of staying competitive in today’s fast-paced business world.
