A concept related to inventory and process manufacturing. When creating a batch you assign and track that particular batch a lot number or batch number, similar to a serial number. Then as batches are filled and shipped who recieves product from which batch can be tracked. This is useful for recalls or when investigating customer complaints.

Lot tracking is not limited to finished goods. Raw materials may also be tracked. In this case if off spec or bad batches are being produced and a bad batch of raw materials were to be identified one would be able to identify and correct or dispose of other finished goods that used the same bad shipment of the offending raw material.
