Context
Traceability is not paperwork. It is the chain of evidence from raw stock to inspection to shipment. If the chain breaks, the part fails audit even if the geometry is perfect.
A usable traceability chain ties each lot to material certs, inspection results, and deviation history so audits can be closed in minutes, not days.
The Trap
The trap is treating traceability as a single document. Auditors look for continuity: material certs, process steps, calibration records, inspection results, and shipment IDs that link together without gaps.
The Geppetto Take
We build traceability as a system, not a file. Every gate in the workflow needs a timestamped record tied to the part and revision. If it is not linked, it is not real.
Evidence / Data
- Audit failures often trace back to missing or mismatched records, not manufacturing errors.
- Digital chains reduce search time and eliminate transcription drift.
Control Actions
- Use a unique part ID across material, process, and inspection.
- Tie calibration status to every measurement record.
- Lock revisions so documentation matches the active CAD.
- Store certificates and inspection data in the same trail.
Checklist
- Material cert linked to lot and heat number.
- Process routing tied to part revision.
- Inspection data tied to calibrated tools.
- Shipment record tied to final inspection report.
What to Send
Send sample material cert, an inspection report, and the process routing for one part.
FAQ
What breaks traceability most often?
Unlinked records across material, process, and inspection.
Can paper logs be compliant?
Yes, but the chain is easier to break and harder to audit.
Do we need full traceability for every part?
It depends on risk, but critical parts should always carry a full chain.
