QMS story: Factory signals become controlled QMS recommendations
Show how factory signals become controlled QMS recommendations.
Step 1 of 6 — Signal detected. A PLC reject spike, with robot and IoT context, raises a quality signal.
Step 2 of 6 — Evidence sealed. The machine signal, timestamp, and calibration context are bound and sealed as evidence.
Step 3 of 6 — QMS record prepared. A quality signal and an NCR recommendation are prepared from the bound machine evidence.
Step 4 of 6 — Human decision required. QA approval is required before the recommendation advances — no automatic disposition.
Step 5 of 6 — Signature recorded. QA records a signature; the recommendation becomes a controlled record.
Step 6 of 6 — Audit packet prepared. An audit trail shows machine-to-QMS traceability; HoldField never commands the line.
Approval: The system prepared a quality signal and an NCR recommendation from machine evidence. Quality engineer must approve. Human approval required before any disposition. No automatic disposition.
Readiness — Machine-to-QMS traceability view: Machine-signal evidence (evidence complete); Calibration context (evidence complete); Root-cause linkage (gap remains). A traceability view from machine signal to QMS record — read-only. HoldField never writes to the PLC or commands the line.
HoldField reads machine signals as data only; QA owns the QMS decision and the line stays under local control.
