Determines how to act according to product demand fluctuations.
How is XYZ Analysis done?
ABC Analysis is done,
The period intervals to be analyzed are determined,
Standard Deviation of the specified period is calculated,
Coefficient Variation is found => Standard Deviation / Period Average,
XYZ Grouping is done (Percentages can be revised according to need);
Y: > 10% & <=25
Z: > 25%
In the presentation below, how to do it is explained in detail visually and a sample document is provided;
