Context
Sample scenario: A multi-lot build uses evidence gates to stabilize the ship window. Delivery windows are not promises without evidence. In managed programs, the schedule is only as strong as the inspection and proof chain behind it.
In practice, a delivery window should only lock after FAI, CMM, and material cert proof are complete. This sample plan shows how evidence gates stabilize the schedule.
The Trap
The trap is assuming a ship date is stable before evidence is complete. That leads to rush inspection, missed documentation, and rework.
The Geppetto Take
We lock the delivery window only after evidence gates pass. It is a discipline: if proof is late, the ship date moves, not the other way around.
Evidence / Data
- Evidence gates (FAI, CMM, certs) predict delivery better than machine hours.
- Missing proof causes last-minute schedule churn.
Control Actions
- Define evidence gates for each build.
- Require pass/fail proof before scheduling shipment.
- Track gate timing as part of the delivery plan.
- Use a proof pack checklist for sign-off.
Checklist
- FAI report approved.
- Material certs linked to lot.
- CMM data archived and signed.
- Packaging and labeling verified.
What to Send
Send your proof requirements and acceptance criteria for shipment.
FAQ
Why is evidence required before shipment?
Because it prevents late rework and audit exposure.
Can we ship before all evidence is complete?
Only with documented risk acceptance.
What is in a proof pack?
FAI, CMM results, material certs, and inspection sign-off.
