Lead time
A lead time is the latency between the initiation and completion of a process. For example, the lead time between the placement of an order and delivery of new cars by a given manufacturer might be between 2 weeks and 6 months, depending on various particularities. One business dictionary defines "manufacturing lead time" as the total time required to manufacture an item, including order preparation time, queue time, setup time, run time, move time, inspection time, and put-away time. For make-to-order products, it is the time between release[vague] of an order and the production and shipment that fulfill that order. For make-to-stock products, it is the time taken from the release of an order to production and receipt into finished goods inventory.
A conventional definition of lead time in a supply chain management context is the time from the moment the customer places an order (the moment the supplier learns of the requirement) to the moment it is ready for delivery. In the absence of finished goods or intermediate (work in progress) inventory, it is the time it takes to actually manufacture the order without any inventory other than raw materials. The Chartered Institute of Procurement & Supply identifies "total lead time" as a combination of "internal lead time" (the time required for the buying organisation's internal processes to progress from identification of a need to the issue of a purchase order) and "external lead time" (the time required for the supplying organisation's processes, including any development required, manufacture, dispatch and delivery). The lead time applicable to material flows within a supply chain may be paralleled by the concept of "information lead time". Mason-Jones and Towill report that reductions in both material flow lead time and information lead time are necessary to secure supply chain performance improvements. Several writers have referred to the importance of "information enriched supply chains" in this context.
In the manufacturing environment, lead time has the same definition as that used in supply chain management, but it includes the time required to ship the parts from the supplier. Shipping time is included because the manufacturing company needs to know when the parts will be available for material requirements planning purposes. It is also possible to include within lead time the time it takes for a company to process and have the part ready for manufacturing once it has been received. The time it takes a company to unload a product from a truck, inspect it, and move it into storage ("put-away time") is not trivial. With tight manufacturing constraints or when a company is using Just In Time manufacturing, it is important for supply chain to know how long their own internal processes take.
Lead time consists of:
Example
Company A needs a part that can be manufactured in two days once Company B has received an order. It takes three days for company A to receive the part once shipped, and one additional day before the part is ready to go into manufacturing.
Possible ways of shortening the lead time:
To best meet the customer needs, a company should work towards the shortest possible lead time in manufacturing, production, and delivery. It can be helped by:
