质检：从检验清单到过程智能的范式跃迁

AQL sampling plans assume statistical independence—but modern supply chains introduce correlated defects across linked sub-assemblies.
Visual inspection alone misses micro-cracks induced by thermal cycling during final packaging, detectable only through non-destructive testing.
QC reports gain authority when linked to root-cause analysis—not just defect counts—and tied to specific machine parameters or batch lots.
Third-party inspections add value only when their methodology aligns with end-user requirements, not generic industry templates.
Real-time defect logging via mobile apps enables trend analysis weeks before monthly summaries—enabling preemptive line adjustments.
Acceptance criteria must reflect functional performance, not just dimensional tolerances—especially for components subject to field vibration or corrosion.
Supplier QC training should focus on interpreting control charts, not memorizing inspection frequencies—statistical literacy prevents false alarms.
Zero-defect rhetoric undermines credibility; credible QC frameworks define acceptable risk thresholds transparently—with mitigation protocols.
Post-shipment quality feedback loops remain broken unless field failure data flows back to engineering—not just customer service databases.
Automated optical inspection gains ROI only when paired with AI-driven anomaly clustering—not just pass/fail binary outputs.
