Start a Lot Traceability Record Before the First Production Order

Traceability is difficult to reconstruct after parts have mixed. Before the first production order, decide what the lot identifier will mean: a material batch, a production run, a shipment or a combination. Put the definition in the work instruction and use it consistently on travelers, inspection records and carton labels where appropriate.

Choose the minimum useful chain

At a minimum, the team should be able to connect a shipped quantity to its product revision, production date or run, critical material batch, inspection disposition and any subcontracted process record. The exact depth depends on product and buyer requirements. Do not claim full serialization if the system only tracks cartons.

Walk one hypothetical return backward. If a buyer reports an issue with a labeled carton, which records can you retrieve, and how long will it take? If the answer depends on an employee remembering the shift, the identifier or record location needs work.

When a buyer asks for traceability, show the scope honestly: what is recorded, what is linked, and what remains outside the system. Offer a sample record with sensitive customer and supplier details removed rather than a broad statement that cannot be tested.

Worked example (illustrative)

For an illustrative batch of housings, carton label L-7 points to production run R-4, its material lot, inspection disposition and shipped quantity. The team practices retrieving those records from the label alone. If the record can only be found by asking the night-shift supervisor, the identifier and filing method need improvement.
