How it works in practice

Analyze representative order combinations and distinguish persistent relationships from temporary promotions. Evaluate whether nearby placement actually reduces work under the picking method used.

Illustrative scenario, not a claim about a client engagement.

What to watch for

A statistical association does not automatically justify adjacency. Products with incompatible storage requirements or heavy traffic may need separation despite frequent joint demand.

A useful question

Does the observed relationship persist outside a single promotion or customer?
