Governance: maintenance logs included in QMS; DMS/MNT-761.

Preventive vs Predictive

Conclusion: Predictive rules cut unplanned stops by 42% vs preventive-only (N=12 lines, 10 weeks). Data: stops 18→10; 0.5–0.7 s dwell stability. Clause/Record: ISO 22000 PRPs; internal SOP OPS-PRD-014. Steps: Deploy threshold-based alerts; add vibration sensors; define stop limits ≤10/day per line. Risk: false positives >10% revert to preventive. Governance: update Ops standard; DMS/SOP-014.

Version/Label Governance & Freeze Windows

Conclusion: Label version errors fell from 0.28% to 0.06% after 72 h freeze (N=96 lots, 8 weeks). Data: changeover 22→14 min; FPY 96.8%→98.9%. Clause/Record: ISO 9001 §7.5 document control; GS1 Digital Link record DL-2024-118.
