"Product quality is everyone's responsibility", high-quality products are produced, managed and controlled, not tested.
"Product quality control is a headache for every enterprise", quality control is a systematic project with its own rules and unique control methods;
If you do not master the correct quality control method, it will be difficult to control the quality of the product, and even some unexpected quality problems will appear, causing great economic losses to the enterprise.
But quality control is by no means easy, which is where the competitiveness of an enterprise lies. A chief technical engineer who has been working for decades, the following summarizes 6 streamlined opinions on quality control, hoping to be helpful to everyone.
1. Do not easily determine the process, and do not change the determined process easily
1) If there is a quality problem with the product, it is necessary to find the root cause, main factor or main manifestation of the problem;
2) Before the problem is figured out, changing the process easily actually conceals the real reason and problem.
2. Process control must have a strong sense of quantification and traceability
1) Quality depends on many factors, don't ignore any details;
2) Use data to control and record any details as much as possible;
3) Failure to control and trace process details will mislead the formulation of corrective and preventive measures.
3. Be patient when solving problems
1) Don't be impetuous, hope to eat a fat man in one breath;
2) Do not ignore the abnormal situation as it seems to have nothing to do with the problem to be solved;
3) Don’t take action when you can’t find out the reason and law, you can control and standardize the influencing factors of the analysis;
4) Review and review some experiences and rules from previous tests and summaries;
5) Once some experience and laws are discovered, it is worthwhile to go deeper and raise it to a theory, even if it costs a little more;
6) You must know that "the embankment of a thousand miles is destroyed by an ant's nest", and you must also know that "the foolish old man moved the mountain".
4. To establish a preventive thinking
1) The highest state of quality management is prevention, not how to save after something goes wrong;
2) Before any quality problem occurs, there must be signs, depending on whether you have methods, means and experience to monitor and identify;
3) When the same quality problem occurs for the second time, great attention should be paid;
4) The daily process and result data should be sorted out with certain tools, and the rules and trends should be found from the sorted results. These rules and displayed trends need to be constantly corrected;
5) Each control element should be as consistent as possible before processing the product.
5. Quality control must have management thinking
1) Do not expect to directly rely on craftsmen to achieve product quality stability;
2) The quality of the product is manufactured, and if the direct manufacturer is not managed, the quality will never be stable;
3) Therefore, it is necessary to observe, pay attention to and study the performance and status of the direct manufacturer of the product, and manage and mobilize these performances and status;
4) If the performance and status of the direct manufacturer of the product are not controlled, once a quality problem occurs, you will always analyze the cause of inaccuracy;
5) Don’t think that if all the process control requirements stipulated in our current process discipline are met, the product quality will be absolutely fine;
6) Therefore, our process control requirements must be continuously improved, and at the same time, we must also manage people well.
6. Listen to more opinions and suggestions
1) Don't think that other people's opinions are worthless if they don't know the reality and can't solve the problem at once;
2) But they, especially the direct manufacturers of the products, can give us a lot of hints and reminders;
3) If you can solve this problem, you don’t have to listen to anyone’s opinions and suggestions; but when you can’t figure it out, you should listen to anyone’s opinions and suggestions, and you should try and experiment, whether you agree or not ;
4) The thinking of quality management often touches the frontier of technology. Even a casual sentence or a complaint may guide or imply a major technological innovation direction. Therefore, professional technicians should pay attention to details and be good at capturing details.
