Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.

|---|---|---|
| Carton (156 units) | Tier 1 | 7-12 days |
| Pallet (973 units) | Tier 2 | 21-30 days |
