XYZ Demand Analysis

Classify your items into X (stable), Y (variable), and Z (erratic) based on the coefficient of variation of their historical demand. All calculations run in your browser; your CSV is never sent to any server.

Parameters

Demand data (CSV)

Each row is an item; columns are periods (demand per period). The first column can be a name or code — it is discarded if non-numeric. Data never leaves your browser. Sample version: maximum 10 series per analysis.

X threshold (max CV)

CV ≤ X threshold → class X (stable).

Y threshold (max CV)

CV ≤ Y threshold → class Y (variable).

Analyses remaining today: 10 of 10.

Preguntas frecuentes

What does XYZ analysis measure?: Demand stability via the coefficient of variation: X is stable, predictable demand; Y is variable; and Z is erratic and hard to forecast.
How does it combine with ABC analysis?: Crossing both gives you a matrix (AX, AZ, CZ…) that prioritizes control: high-value, erratic-demand items (AZ) need the most attention.
