한국어Lead time
Concept
The total time from the start of an order or part until it is finished, including all waiting. In most plants, waiting makes up far more of it than actual work.
Description
Lead time, in German Durchlaufzeit, is the full time a part or order needs to move through a process, from start to finish. It includes processing, but also queues, transport, inspection and every other wait. Seen from the customer, lead time can also mean the time from order to delivery.
In many plants, most of the lead time is waiting, not work. That is why lead time is a key figure on a value stream map, shown next to the processing time of each step. Shortening it usually means reducing queues and work in progress, smaller batches and a steadier flow. Little's law, a rule from queueing theory, links the three: work in progress equals throughput times lead time.
