5 Features of Just In Time Production
and, having FG stock ready is not JIT.
1 Article for the Week:
Many people think that having FG stock to meet the customer’s demand is Just-In-Time (JIT) manufacturing. No.
You'll be able to serve the customers, but this is not JIT.
JIT manufacturing emphasises on pull production, only when there is a trigger from the customer, the upstream processes starts manufacturing. This trigger depends on the lead-time of manufacturing (not including the waiting and other wastes in the processes)
You’ll achieve JIT when:
1. The product flows from one process to the next without waiting
2. Set-up times are very less (target 1 min)
3. No Defects arise in the processes (zero defects)
4. Work-In-Process is minimal (target 1 piece)
5. No inspections (as there are no defects)
The moment you start the first process, the product should continuously move through the value stream and becomes a Finished Product - without delays, stoppages, reworks and other wastes. This is called JIT.
Many auto OEMs are asking their vendors to keep 5~7 days of stock as FG. This may be required for the unforeseen business situations. But, please this is not JIT.

“In some areas of life, value is unlocked by starting. Even a five-minute workout or a short walk can reset your mood and benefit your body.
In other areas, value is unlocked by finishing. It does you no good to build a bridge halfway across the river. You need to complete the project to realize the value.
Do you need to start or finish? Are you building a body or building a bridge?” - Tweet by James Clear
