Lead time

from Wikipedia, the free encyclopedia

Procurement time (also procurement duration or procurement deadline ) in materials management , in particular in determining material requirements , is the period of time between the placing of an order or an order for goods ( production material , product or intermediate goods ) and the availability of these goods.


In -house production , the event is ordering replaced by the event issuing of the construction contract .

The lead time is made up of the following periods:

Critical lead time

There is also the critical replenishment lead time (KWBZ).

For normal purchased parts it indicates the shortened - fastest possible - replacement time. So it is usually shorter than the "normal" replenishment lead time.

For assemblies that are manufactured by the company itself, the KWBZ stands for the time it takes to manufacture the assembly if none of the required secondary requirements are in stock.
