In order to directly grasp the quality of the supplier's goods, the buyer can send a resident representative to the supplier, whose main responsibility is to put forward specific commodity quality requirements to the supplier and understand the supplier's quality management, such as the establishment of quality management organization, the preparation of quality system documents, the establishment and implementation of quality system, product design, production, packaging and inspection. In particular, supervise the final inspection and test before leaving the factory, and verify and confirm the quality certification materials issued by suppliers. For suppliers who have long-term and stable business contacts, established a fixed purchase and sale relationship, and have large purchase volume, strong technology and strict quality requirements, the purchaser can also send a quality inspection team to the permanent supplier, not only to conduct a comprehensive and comprehensive inspection and supervision on the quality of the goods, but also to supervise the full implementation of the sales contract, so as to ensure timely production and delivery and meet all requirements of the purchaser. At the same time, the quality inspection team can also reflect the problems and new requirements of purchased products to suppliers, so as to urge suppliers to improve and improve product quality and continuously develop new products that users need.

This method is often used in supplier quality management and control, and its advantages mainly include the following points.

(1) All-round and all-round inspection and supervision of the supplier's product quality can find problems in time, facilitate the supplier to rework in time and reduce the supplier's quality cost.

(2) Finding problems from the source facilitates rapid response and helps enterprises to obtain high-quality purchased goods.

(3) IOC can control according to the actual use of enterprises and the quality of purchased goods, and a project can be strictly inspected with strong pertinence.

3) Regular or irregular supervision and inspection

Due to the changes in the internal and external environment of enterprises, the production situation of suppliers will inevitably change. The buyer should know the changes in time and ask the supplier to report some major changes in production to the buyer in time. Major changes have taken place in product design or structure, manufacturing process, inspection and test equipment and procedures, etc. The supplier shall actively report the situation to the buyer. After receiving the report, the purchaser should carefully analyze the situation, and if necessary, go to the supplier for direct understanding, mainly to understand the impact on product quality. In most cases, in order to improve product quality and production efficiency, suppliers change product design and adopt new materials, new equipment and new technology, which is conducive to ensuring product quality. However, we must also see that any change has an adaptation process, which is likely to cause instability of commodity quality in the initial stage of change. This needs to be checked by strengthening the final inspection and testing.

5) General sorting

The main purpose of ranking is to evaluate the quality and comprehensive ability of suppliers and provide decision-making basis for whether to retain or replace suppliers. The general criteria for classification are as follows:

(1) Qualified rate of quality assurance batch of SOA suppliers: generally, it is required to be no less than 95%.

(2)IOC batch pass rate: generally, it is required to be no less than 95%.

(3) Quality problems after commodity input: Generally speaking, the qualification rate of the whole process is required to be no less than 85% (which varies greatly from product to product).

(4) Attitude and speed of responding to CAR's corrective action report: respond in time, make a convincing analysis of the problem, and take corrective and preventive measures (or change the operation documents, or make process improvement, etc.). ).

(5) Fulfillment of delivery date: Be able to actively fulfill the contract and make a reasonable explanation for the delay in delivery.

(6) Audit result: the audit score is at least 60 points.

(7) Cooperation with the personnel of this enterprise: actively cooperate with the affairs of the demand side and cooperate well.

The product of the above items is used as the total score of sorting. The finishing cycle is usually once every quarter or once every six months.

6) Help suppliers to introduce new systems and methods.

In order to effectively control the quality of purchased goods, the purchaser should introduce advanced quality management means and technical methods summarized by himself for many years, actively help and guide suppliers to greatly improve their quality management level and technical level in a short time, and enhance their quality assurance ability. It is beneficial for the supplier and the purchaser to give some help to the supplier. There are many ways to help suppliers, the main purpose is not to expand production capacity but to improve the quality of goods. Focusing on improving quality can help suppliers organize technical training for relevant personnel, carry out technical transformation of equipment, and realize standardization and standardization of inspection and testing. Implement ISO9000 family standards, strive for quality system certification, and help suppliers introduce 6Sigma system. The focus of helping and promoting suppliers is to strengthen the weak links of commodity quality and solve the key problems affecting commodity quality.
