Velocity and ABC classification
Velocity describes how frequently or intensely an item is demanded or handled. ABC classification groups items according to a selected measure. Sales value, units, order lines, and visits can produce different classifications.
How it works in practice
Choose the measure that supports the intended decision and document its time window. Compare categories against seasonal patterns and physical handling requirements before applying location or counting rules.
A warehouse example

What to watch for
