Meaning
Verification procedures confirm that every component in a finished product can be tracked back to its original source and manufacturing conditions. A lot traceability audit examines the digital and physical records that link a serial number to a specific batch of raw material. It governs the ability of a company to perform a targeted recall if a defect is discovered.
Batch Verification
Documentation must show a continuous chain of custody from the supplier to the warehouse. During a lot traceability audit, an inspector picks a random unit from the shelf and requires the staff to find the material certificates for every part inside it.
Supply Chain
Sub tier vendors must provide the same level of detail as the primary manufacturer. If a lot traceability audit fails at the third tier, the whole assembly is considered non compliant for certain regulated industries.
Inventory Record
Keeping accurate logs of when a batch was opened and used is a daily requirement. The cost of a failed audit is the quarantine of all finished goods until the records are corrected. Demonstrating this capability is a prerequisite for moving from a pilot run to full scale production in the aerospace and medical sectors.
