 "title": "Lot, Serial or Item: Which Identity Level Does an Operational Use Case Need?",
 "description": "Choose lot, serial or item-level identity from the operational action and evidence needed, not from an assumption that every product needs serialisation.",
 "territory": "data",
 "category": null,
 "direct_answer": "Choose the **lowest identity granularity that still lets the operation take the required action and support the evidence it needs**. A lot or batch is enough when every affected unit can be treated together. Item-level identity becomes useful when the action depends on the history, condition, custody or status of one exact unit.",
