| Area | What the record should show |
|---|---|
| Control | Define forecasts, firm windows, price reviews, capacity reservation, tooling, improvement, change control, exit and transition support. |
| Evidence | Track commitments, actual volume, performance, price adjustments, investments, renewals and termination rights. |
| Tradeoff | Long duration can improve stability while locking in a weak specification or pricing mechanism. Build review points into the agreement. |
