Lean Time and Lead Time

Lean Time versus Lean Time
Shahid Mahmood Ch., Manager, Pakistan
Lead Time is the total plan time required to deliver or redeliver stores i.e. the time taken from "ask/indent" to the delivery note at the gate of the indentor.
Now that this is clear, it's more easy to understand lean time...
Lean Time is the minimum possible time (cutting down lead time) required to deliver the goods, it's always in discussion for all the bottle neck items. If you need more explanation plese let me know.

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.

Lean Time and Lead Time

Lead time" is clear, but "lean time" is not really standardized.
But one definition that would make sense is the minimum lead time if the internal buffers and waiting times are minimized.
The point is that the lead time is longer if the wip is bigger.
