  • ISO9001
    ISO9001 The ISO9001 quality management system certification standard is a summary of the development of management theory and management practice in many countries, especially developed countries, over the years. It embodies a management philosophy and quality management method and mode, and has been adopted by more than 100 countries and regions in the world. The ISO9001 international quality management system standard is the most mature set of management systems and standards in the world so far, and is the root of enterprise development and growth. The enterprise organization's passing the ISO9000 quality management system certification has the following significance:1. It can improve the internal management of the organization, institutionalize, systematize and legalize quality management, improve product quality and ensure the stability of product quality;2. Show respect for the rights and interests of consumers and responsibility to the society, enhance the trust of consumers, make consumers feel at ease, so that they can use their products with confidence, improve the market competitiveness of products, and take this opportunity to establish the image of the organization, improve the popularity of the organization, and form a famous brand enterprise;3. ISO9000 quality management system certification is conducive to the development of export-oriented economy and the expansion of market share. It is the entrance ticket for government procurement and other bidding projects, the entrance permit for the organization to march into overseas markets, and the powerful weapon to eliminate trade barriers;4. Through the establishment of ISO9000 quality management system, we can draw inferences from one instance to establish and improve other management systems;5. Passing ISO9000 certification can be cited, which is not comparable to general advertising investment, planning investment, management investment or training, and has comprehensive benefits; They can also enjoy the preferential policies of the state and the key support to the licensed units.The implementation of ISO9000 standards is closely related to the reform of modern enterprises in China. The difference is that the former deals with the micro environment of the organization, while the latter focuses on the macro environment of the organization. It can be seen that the ISO9000 family of standards is very suitable for China's national conditions. Therefore, the state explicitly stipulates that the ISO9000 family of standards will be fully implemented during the Ninth Five Year Plan period.ISO9000 family standard certification can also be understood as quality management system registration, that is, a fair third-party institution approved by the state, the certification institution, evaluates the organization's quality management system according to ISO9000 family standards, proves to the public that the organization's quality management system conforms to ISO9000 family standards and provides qualified products. The public can trust the consistency of the organization's service commitment and the organization's product quality.The ISO9000 family of standards is not only implemented in all developed countries, but also gradually joined by developing countries. ISO has become a veritable technical world alliance. The reason for this situation is that in addition to the huge practical benefits it can bring to the organization, the more profound reason is that the ISO9000 family of standards is an inevitable thing in the development of human civilization.
