A location guides the search, not the identity check
The correct address does not establish that it holds the correct product. A similar item may have been placed there or stock moved previously. Product identification and quantity still matter at collection.
If the order specifies a batch or expiry requirement, make it visible during the operation. The picker should not infer it from a general description.
A scan needs a defined comparison
Reading a label is useful when it is checked against something specific: the order line, packaging unit or required batch. Recording an arbitrary code does not confirm a match.
The response to a discrepancy matters too. If the operator may proceed, the team needs to know when that is an authorised exception and who makes the decision.
Measure the source of the error
Distinguish product, quantity, batch and unit-of-measure mistakes. Each may require a different improvement to labelling, data or working methods.
For a supervisor, return trips and their causes are useful measures. WMS can support picking checks against orders. A well-defined process identifies discrepancies before goods reach final packing.
