Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (79 units) | Tier 1 | 14-21 days |
| Pallet (1971 units) | Tier 2 | 30-45 days |
| Container (11448 units) | Tier 3 | 14-21 days |
