REPLENISHMENT TIMING & AVAILABILITY
Effective Lead Time
Effective lead time is the elapsed replenishment time used for a defined planning decision. It should include the relevant steps between its stated start and stock becoming usable, rather than relying only on a supplier’s quoted production time.
EFFECTIVE LEAD TIME IN PRACTICE
- Set the endpointsName the planning start and availability event.
- Capture the stagesTrack approval, supply, transport and receiving.
- Review variabilityUse actual outcomes and exceptions.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Ten days quoted. Thirteen days usable.
An illustrative replenishment takes one day for internal approval, ten days from order placement to arrival and two days for receiving release. From the initial trigger to usable stock it takes 13 calendar days, assuming sequential stages. A ten-day supplier figure answers a narrower question.
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 Effective Lead Time
Is supplier production time always enough?
No. Other stages can matter.
Does dock arrival mean usable stock?
Not always. Release may follow later.
Should all stage times simply be added?
Only when they are sequential and use compatible definitions.
