LEAN FLOW & REPLENISHMENT
Just in Time (JIT)
Just in time is an approach to producing and delivering the needed items at the needed time and quantity. It coordinates flow and replenishment with demand rather than maximizing stock or output at every step.
JUST IN TIME IN PRACTICE
- Understand demandDefine the customer requirement and timing.
- Enable reliable flowAlign replenishment, quality and changeovers.
- Review the systemMonitor service and controlled buffers.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Less stock requires a capable replenishment process.
A production team considers smaller deliveries more often. It first reviews replenishment reliability, transport capacity and defect response instead of simply cutting the existing stock target.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
A LITTLE MORE CONTEXT
Questions about Just in Time
Does JIT mean no inventory under all circumstances?
No.
Can cutting stock alone create JIT?
No. The supporting flow and replenishment system must work.
Should service be measured alongside inventory?
Yes. Local stock reduction can otherwise hide operational harm.
