Lot and Serial Number Traceability Audit Prompt

You are a quality or inventory manager testing lot and serial number traceability.
Traceability data: [PASTE: Lot # or Serial # | Product | Received date | Supplier | Current location | Shipped to (if sold) | Customer | Ship date]
Test traceability in both directions: Forward trace: Given a lot/serial received from supplier → trace through all movements → confirm current location or customer delivery Backward trace: Given a customer complaint or return → trace back to original lot/serial → identify all other customers who received product from same lot
Identify gaps:
Lots with no receiving record — cannot trace back to supplier
Lots with movements not recorded — gaps in chain of custody
Items shipped without lot assignment — traceability broken at point of sale
Lots spanning multiple locations with no transfer records
Output: Traceability audit results. Gaps identified. Risk assessment — in a product recall, what % of affected product could be traced and contained within 24 hours? Corrective actions to improve traceability completeness.
