How do I diagnose my supply chain health?

Use Mathnal's free Diagnostic Suite. Inventory Health Check scores across 10 dimensions. Forecasting Audit detects patterns and selects models. Both run in-browser, no data leaves your machine.

What is a good MAPE for supply chain forecasting?

Below 10% excellent, 10-20% good, 20-30% acceptable, above 30% needs intervention. Always assess alongside forecast bias.

What is ABC-XYZ classification?

ABC ranks products by revenue (A=top 80%, B=next 15%, C=bottom 5%). XYZ ranks by demand variability (X=stable, Y=moderate, Z=erratic). Combined for inventory policy decisions.
