Lean Time and Lead Time
Mohammad Ajlouni, Business Consultant, Jordan
I would say that there is nothing called lean time. There is only lead time.
Lean aims at reducing the lead time, but it is still called lead time.
Manufacturing lead time
is the door-to-door time from the minute raw materials arrive at the stores, to the minute they leave the shipping docks.
A wider range lead time can be looked at as the the order-to-cash lead time
, which is the time between placing an order to the time cash has been received on this order.
The latter lead time includes administrative operations in addition to the manufacturing lead time.
