How Do Factories Trace Defects to Individual Production Batches?

Batch traceability uses material lots, cutting records, line identifiers, and inspection logs.

Identify the process causing the defect rather than relying on final sorting alone. Material, cutting, machine settings, handling, and operator methods can interact; record the affected style, size, lot, and operation so corrective action can be verified before the same issue continues through production.
