Supplier quality management and control of the effective method
Suppliers to provide products continue to meet the procurement requirements, the purchaser shall according to the actual situation, take the following effective management and control method.
1) the development of joint quality plan
Procurement of modern commodity, not only to buy the commodity itself, but also to purchase supplier in product design, manufacturing processes, quality control, technical assistance and other abilities. In order to effectively purchase supplier in this capacity, the need to supply and demand sides of the ability to peer coordination, coordinated approach is to develop joint quality plan. Joint quality plan to include economic, technology, three aspects of management.
( 1) the economic aspects. The content includes the value analysis, in order to assist the buyer from contract to achieve maximum value; on the cost, quality and delivery and other aspects of comprehensive balance, in order to achieve the best cost; to use costs are reviewed, so that the whole product life cycle cost is reduced to the lowest level. In some cases, jointly developed the economic aspects of the plan can be modified in the contract of guarantee clause or field service terms.
( 2) the technical aspects. Need to develop a series of technical plan, which relates to the buyer and supplier of both their respective functions. Mainly include:
Product design. In this aspect of the plan is to make clear the meaning of technical requirements, identification of product safety and function play an important role in the quality characteristics, drawn on for reliability and other relevant requirements, necessary to provide sensory inspection standard.
The process of design. This plan is defined in the supplier distribution in production operations, the common use of high, fine, sharp equipment, clarify the key process parameters and its meaning, establish the identification and tracing system. When the purchaser that mutual consultation process design for its unique needs is essential, can request, no purchaser approval, without changing the prior process design and method of operation.
The production of. This plan is refers to the personnel training and assessment requirements, such as, process device standards, process control program, equipment maintenance, information and documentation requirements.
The inspection and testing. This plan is refers to the measurement, test method standard, testing equipment capacity and regular inspection, moreover also relates to the quality standard of.
( 3) the management of. This program is mainly to identify essential management activities, and establish a clear responsibility to carry out activities. In addition, but also for buyers and sellers to communicate channel work, establish rapid, sensitive information feedback system, variable one-way communication program for two ways of communication. In the complex contracts, various procedures and system correspondingly became complicated, need to draw a flow chart and the provisions of special terms, in order to ensure the smooth operator communication line.
2) to the supplier sent resident representative
Direct supplier product quality status, by purchasing direction supplier sent resident representative, its main duty is to put forward specific commodity supplier quality requirements, the supplier quality management of the situation, such as quality management institution, compiling documents of quality system, quality system establishment and implementation, product design, production, packaging, testing and so on, especially to the factory before the final inspection and testing are to be monitored, the supplier quality issued documents to verify and confirm, played in the supplier quality check function. On the long-term stability of business contacts, establish a fixed relationship between the buying and selling, purchasing large quantities, technical strong, strict quality requirements to the suppliers, buyers can also sent inspection group permanent supplier, not only on the quality of goods for full, comprehensive inspection and supervision, and supervision of contract full implementation, ensure timely production, timely delivery, to meet the various requirements of purchaser. At the same time the QC group can also reflect the purchased products from suppliers in the use process problem on products and new requirement, push supplier to improve and enhance product quality and continuous development of user needs new products.
This method is the supplier quality management and control is a kind of commonly used method, its main advantages are the following.
( 1) the supplier product quality full, comprehensive inspection and supervision, to find the problem in time, to facilitate suppliers timely rework, reducing the supplier's quality cost.
( 2 ) from the source to find problems, to facilitate rapid response, high-quality procurement of goods for the enterprise to obtain favorable.
( 3) according to the enterprise actual situation and quality control of IOC, devoted to the rigorous examination of a project, strong pertinence.
Regular or irregular supervision and inspection
( 4) grasp the supplier status changes
Due to the change of environment of Ministry of enterprise inside and outside, the supplier's production status will change. The purchaser shall grasp its change situation, the production of some of the major changes, should require the supplier to purchase party report. Products such as the design and structure of the major changes, major changes in the manufacturing process, inspection and test equipment and procedures of major change, the supplier shall actively report to explain the situation to purchaser. Buy side after receiving the report, should be analysed seriously, when necessary, to understand the direct suppliers, mainly should make clear the effect on product quality. In most cases the supplier product design, adopt new materials, new equipment, new technology to improve product quality and production efficiency, to ensure the quality of the commodity is useful. But also we should pay attention to, any kind of change is a process of adaptation, in the initial stage of change is easy to cause the instability of product quality. This need by strengthening the final inspection and testing to ensure.
3 regular sort
Sort the main purpose is to assess the supplier 's quality and comprehensive ability, as well as for whether to retain, replacement of suppliers to provide basis for decision making. Sort of general guidelines are as follows:
( 1) the SOA supplier quality assurance qualified rate of not less than 95%: General requirements.
( 2) the IOC batch passing rate of not less than 95%: General requirements.
( 3) the quality of commodity inputs: General requirements general process through the qualified rate of not less than 85% (due to different products and have bigger difference ).
( 4) corrective action report CAR attitude and velocity: a timely response, to make a compelling analysis, and corrective and preventive action ( or change a file, or process improvement etc.).
( 5) delivery performance: can actively performing the contract, and to make reasonable description of delayed delivery.
( 6) results of audits: audit scores at least 60 points.
