Why Visualize These Metrics?
Spot Trends & Anomalies
Charts instantly reveal patterns—like a gradual decline in QC pass rates or a spike in refunds for a specific product—that rows of data can hide.
Assess Supplier Performance
Compare QC approval and refund ratios across different suppliers to make informed sourcing decisions and negotiate better terms.
Forecast & Reduce Costs
High refund rates directly impact profitability. Tracking them helps forecast losses and pinpoint the root causes for corrective action.
Quality Assurance Focus
Correlate low QC approval rates with high refunds to identify which quality failures ultimately lead to customer returns.
