Production Events and Traceability Evidence · Meaning and Judgment
The review items for “4. Detail Verification” are as follows. Work and records: Materials, repairs, downstream semi-finished products; decision and implementation criteria: Verify the basis for the judgment and the scope of the links.
The production history cannot be reconstructed from the current status alone. Input, replacement, inspection, hold, repair, and reinspection must be recorded as separate events, with the relationships between upstream and downstream semi-finished products and the original product linked together.
For one representative manufacturing number, trace the materials used and inspection results, and conversely compare the range of products affected by a specific material LOT.
Production Events and Traceability Evidence · Execution and Validation
When reviewing “A Consistent Usage Flow for Lookup, Selection, Process, and Details” in this chapter, product, manufacturing number, process, time, operator, and material LOT must be interpreted using the same criteria. Those responsible for production, materials, quality, and customer response must verify not only the values they enter, but also the information received from the previous step and the status passed to the next step.
Confirm cases involving changes, cancellations, or omissions alongside normal processing results. Record where judgments differ between production, materials, quality, and customer response, and agree on who will approve them and on what basis. Any scope of automation that cannot be verified from existing materials should remain a review item before implementation.
