A reliable traceability system fortifies the supply chain right from the start of production. Should a faulty part be detected further along the production line it will be easier to pinpoint the source of the problem and quickly rectify the situation.
Crucial information for product tracking like serial numbers, place of origin, model number and source manufacturer can be encapsulated into a barcode affixed to a part. To ensure each part carries this data along the supply chain, this barcode is usually a direct part mark (DPM) – a marking that is etched or printed directly to ensure it is permanent and inseparable from the part itself. Manufacturers can also facilitate traceability by using labels.
