From Sample Manifold to Repeat Order: The Qualification Gates We Document

%s

A sample proves that a design can be made. A repeat order proves that it can be made again with the same interfaces and the same verification. The difference is documentation: approved drawing revision, material traceability, joint method, inspection points and the test record.

This note sets out the gates we document between sample approval and batch production, without attributing them to any named project or customer.

Key Points

• Freeze the approved drawing revision and the interface schedule before batch release.
• Carry material traceability and inspection points across from the sample build.
• Keep verification records comparable so a later batch can be audited against the first.
