1. Unqualified products are not accepted.
Before production and processing, employees should check whether the products delivered in the previous process are qualified according to regulations, and have the right to reject them once problems are found, and feedback the previous process in time. The personnel in the previous process need to stop processing immediately, trace the reasons and take countermeasures, so as to find the quality problems in time and correct them, and avoid the waste caused by the continued processing of unqualified products.
2. Do not produce unqualified products.
After accepting the qualified products of the previous process, strictly implement the operation specifications in the processing of this position to ensure the processing quality of the products. Preparations such as inspection and confirmation before operation are fully in place, and the process conditions in operation are always concerned, so as to avoid or find anomalies as soon as possible and reduce the probability of producing unqualified products. Adequate preparation and confirmation in the process is the key to not manufacturing unqualified products. Only by not producing unqualified products can it be possible not to flow out and accept unqualified products.
3. Unqualified products will not flow out
When employees finish processing in this process, they need to check and confirm the product quality. Once the defective products are found, they must be stopped in time to cut off the defective products in this process and complete the disposal and preventive measures of this process. Ensure the delivery of qualified products, otherwise it will be rejected by the next "customer".
The significance of the three principles
The implementation of "three noes" has made every post and employee establish the belief of "producing products that satisfy themselves and customers", and an invisible quality chain runs through the whole production process. Restrain each operator, so that all links of the process are always in a good controlled state and enter an orderly virtuous circle.
The principle of "three noes" is the quality policy, quality goal or propaganda slogan of many companies. No product can be completed by one person alone. Products are always divided into processes and processes, including work assistance between functional departments. As long as there is a problem in one link, it will affect the quality of the whole product or work, and the "three noes" principle is the quality assurance principle of each link.
The implementation of the "three noes" principle has introduced the market relationship of "supplier-customer", and everyone is both a supplier and a customer. As users, manufacturers and suppliers of products, everyone should firmly establish the concept of "the next process is the customer".
