Introduction: Win-win relationships have become a model of cooperation between supply chain companies. Therefore, in order to embody the idea of ??supply chain in procurement management, supplier management should focus on how to establish a win-win relationship with suppliers. relationships and maintaining and maintaining win-win relationships. How to manage supplier quality

1) Develop a joint quality plan

When purchasing modern goods, you not only purchase the goods themselves, but also purchase the supplier’s experience in product design, manufacturing process, quality control, Ability to provide technical assistance, etc. To effectively purchase this capability from suppliers, it is necessary to coordinate the capabilities of both supply and demand sides on an equal footing. The method of coordination is to develop a joint quality plan. Joint quality plans generally include three aspects: economics, technology, and management.

(1) Economic aspect. This aspect includes value analysis to assist buyers in obtaining the maximum value from the contract; comprehensive balancing of cost, quality and delivery time to achieve the best cost; review of usage costs to ensure that the product is fully Life cycle costs are reduced to a minimum. In some cases, joint financial planning can modify the warranty or on-site service provisions in the contract.

(2) Technical aspects. A series of technical plans need to be developed, which involve the respective functions of both the purchaser and the supplier. Mainly include:

①Product design. The plan in this regard is to clarify the meaning of the technical requirements, identify the quality characteristics that play an important role in the safety and functionality of the product, formulate reliability and other related requirements, and provide sensory inspection standards if necessary.

②Process design. The plan in this area refers to allocating production operations within suppliers, using high-quality, sophisticated and cutting-edge equipment, clarifying the parameters and their meanings of key processes, and establishing an identification and tracing system. When the purchaser believes that the process design agreed upon by both parties is indispensable to its unique needs, it may make a request. Without the purchaser's approval, the process design and operation methods may not be changed in advance without authorization.

③Production. Plans in this area refer to requirements for personnel training and assessment, such as standards for process equipment, processing control program tables, equipment maintenance tables, information and document requirements.

④Inspection and testing. Plans in this area refer to standardization of measurement and test methods, test equipment capabilities and periodic inspections, in addition to quality standards.

(3) Management. Planning in this area focuses on identifying essential management activities and establishing clear accountability for carrying them out. In addition, it is necessary to work on communication channels between buyers and sellers, establish a rapid and sensitive information feedback system, and change one-way communication into dual-process multi-way communication. In complex contracts, various procedures and systems become correspondingly complex, requiring flow charts and special clauses to ensure smooth communication lines.

2) Send a permanent representative to the supplier

In order to directly understand the quality status of the supplier's goods, the purchasing direction can send a permanent representative to the supplier. His main responsibility is to raise issues with the supplier. Specific product quality requirements, and understand the relevant situation of the supplier's quality management, such as the establishment of quality management organizations, the preparation of quality system documents, the establishment and implementation of quality systems, product design, production, packaging, inspection, etc., especially for The final inspection and testing before leaving the factory must be supervised, and the quality certification materials issued by the supplier must be verified and confirmed, which plays a role in quality control within the supplier. For suppliers that have long-term and stable business contacts, establish fixed purchase and sales relationships, purchase large quantities, have strong technical skills, and have strict quality requirements, the purchaser can also send a quality inspection team to the supplier to not only conduct a full and comprehensive inspection of the quality of the goods. We must conduct local inspection and supervision, and also supervise the comprehensive implementation of the sales contract to ensure timely production and timely delivery to meet all aspects of the purchaser's requirements. At the same time, the quality inspection team can also report problems in the use of purchased products and new requirements for products to suppliers, prompting suppliers to improve and improve product quality and continuously develop new products needed by users.

This method is a commonly used method for supplier quality management and control. Its main advantages are as follows.

(1) Conduct a full and comprehensive inspection and supervision of the quality of the supplier's goods, which can promptly identify problems, facilitate timely rework by the supplier, and reduce the supplier's quality cost.

(2) Identifying problems from the source facilitates rapid response, which is beneficial to enterprises in obtaining high-quality purchased goods.

(3) Based on the actual usage of the company and the quality control IOC of the incoming goods, a specific item can be strictly inspected, which is highly targeted.

3) Regular or irregular supervision and inspection

Due to changes in the internal and external environment of the enterprise, the production status of suppliers will inevitably change accordingly. The purchaser should keep abreast of the changes and require the supplier to report to the purchaser timely any major changes in production. Such as major changes in product design or structure, major changes in manufacturing processes, major changes in inspection and test equipment and procedures, etc., suppliers should proactively report and explain the situation to the purchaser. After receiving the report, the purchaser must carefully analyze the situation, and if necessary, go to the supplier to understand directly, mainly to understand the impact on product quality. In most cases, suppliers change product designs and adopt new materials, new equipment, and new processes in order to improve product quality and production efficiency, which is beneficial to ensuring product quality. However, it must also be noted that any change involves an adaptation process, which can easily cause instability in product quality in the initial stage of change. This requires strengthening final inspection and testing.

4) Regular sorting

The main purpose of sorting is to evaluate the quality and comprehensive capabilities of suppliers, and to provide a basis for decision-making on whether to retain or replace suppliers. The general criteria for sorting are as follows:

(1) SOA supplier quality assurance batch pass rate: the general requirement cannot be less than 95%.

(2)IOC batch pass rate: the general requirement is not less than 95%.

(3) Quality issues after product input: It is generally required that the overall pass rate of the process is not less than 85% (it varies greatly depending on the product).

(4) Attitude and speed in replying to corrective action report CAR: timely response is required, convincing analysis of the problem is required, and corrective and preventive measures (or changes to operating documents, or process improvements, etc.) ).

(5) Delivery date performance: Able to actively perform the contract and make reasonable explanations for delayed delivery.

(6) Audit results: The audit score is at least 60 points.

(7) Cooperation with the company’s personnel: Actively cooperate with the buyer in various matters and cooperate well.

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

5) Help suppliers introduce new systems and methods

In order to effectively control the quality of purchased goods, purchasers should introduce to suppliers advanced quality management methods and methods that they have summarized over many years. Technical methods, proactively help and guide suppliers to greatly improve quality management and technical levels in a short period of time, and enhance quality assurance capabilities. It is beneficial to the supplier if the purchaser provides certain help to the supplier, and it is also beneficial to the purchaser itself. Help for suppliers is multi-faceted, and the main purpose is not to expand production capacity but to improve product quality. Focusing on improving quality, we can help suppliers organize technical training for relevant personnel, carry out technical transformation of equipment, and achieve standardization and normalization of inspection and testing. Implement ISO9000 family standards, strive for quality system certification, and help suppliers introduce the 6Sigma system, etc. The focus of assistance to suppliers is to strengthen weak links in product quality and solve key issues that affect product quality.
