Question 1

How do I diagnose my supply chain health?

Accepted Answer

Use Mathnal's free Supply Chain Diagnostic Suite. The Inventory Health Check analyses products across 10 dimensions — demand variability, forecast error, lead time risk, safety stock adequacy, ABC-XYZ classification, warehousing efficiency, transport cost, production planning, and decision-making speed. The Forecasting Audit detects trend and seasonality, auto-selects the best model, and outputs MAPE plus bias. Both tools run entirely in your browser.

Question 2

What is a supply chain health score?

Accepted Answer

A composite metric rating supply chain performance across multiple dimensions on a 0-100 scale. Mathnal evaluates 10 dimensions: demand profile, risk exposure, forecast accuracy, lead time reliability, transportation efficiency, warehousing utilisation, production alignment, inventory optimisation, decision speed, and overall maturity. Above 80 is strong; below 50 signals urgent intervention.

Question 3

How to check if my demand forecast is accurate?

Accepted Answer

Upload historical sales data (Excel or CSV) to the Forecasting Diagnostic Tool. It detects time series patterns (trend, seasonality, variability), selects the best model (Moving Average, Exponential Smoothing, Holt, Holt-Winters), and calculates MAPE and forecast bias. MAPE below 10% is excellent, 10-20% good, 20-30% acceptable, above 30% needs intervention.

Question 4

What are the best free supply chain diagnostic tools?

Accepted Answer

Mathnal Analytics offers two free, no-signup tools: (1) Inventory Health Check — 10-dimension scoring with safety stock, reorder point, and ABC-XYZ classification; (2) Forecasting Accuracy Audit — upload sales data, detect patterns, auto-select models, get MAPE and bias. Both run in-browser with zero data sent to servers.

Question 5

What is ABC-XYZ inventory classification?

Accepted Answer

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: AX items get precise ML forecasting and lean inventory; CZ items get simplified rules and buffer stock. Mathnal's diagnostic auto-classifies products using this framework.
