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.
