4. Turning Charts into Actionable Insights
| Chart Trend | Potential Problem | Possible Action |
|---|---|---|
| ↗ Rising Refund Ratio + ↘ Falling Pass Rate | Systemic decline in supplier quality. | Re-negotiate with supplier, intensify inspections, or initiate a supplier change. |
| → Stable Pass Rate + ↗ Rising Refund Ratio | QC standards may be too loose, missing flaws. | Review and tighten QC checkpoints, retrain QC staff. |
| ↗ Spiking Shipping Costs | Changed packaging, incorrect weight logging, or carrier price hikes. | Audit packaging process, consolidate shipments, re-evaluate carrier contracts. |
