Inspection items of inspection steps performed in processes 40 to 70, namely, in the processes of parts incoming, production, outgoing and market, and quality defect information items generated in connection with these inspections, are registered in advance in a code master database 17 as systematized codes. A part ID unique to a given part and a product ID unique to a given product are correlatively recorded in a part bar code label 81 and in a product bar code label 82 respectively. These bar code labels 81 and 82 are affixed to each part and product. In each of the processes 40 to 70, the part IDs or the product IDs are read, inspection results and quality defect information are input, and information is stored in databases 7, 9, 12, 14 and 16, whereby the quality history of each product is managed.
