One of the technical directors who have worked for decades, summed up the following 6-point streamlined comments on quality control, and hope to help everyone.

"Product quality, everyone is responsible." Quality products are manufactured, managed and controlled, not tested.

“Control of product quality is a headache for every enterprise.” Quality control is a systematic project with its own laws and unique control methods. If you do not master the correct quality control methods, it is difficult to control the quality of the products, even There will be some unexpected quality problems that will cause great economic losses to the company. But quality control is not an easy task. This is where the competitiveness of the company lies.

1. Don't easily determine the process, make sure the process is not easy to change

1) The quality of the product, to find the root cause, main factors or main performance of the problem;

2) Before you figure out the problem, changing the process easily masks the real cause and problem.

2. Process control should have a strong sense of quantification and traceability

1) Quality depends on many factors, don't ignore any details;

2) Any details should be controlled and recorded with data as much as possible;

3) Process details without control and traceability will mislead the development of corrective and preventive measures.

3. Solve problems and be patient

1) Can not be impetuous, I hope to eat a fat man in one breath;

2) Find abnormal situations and don't ignore them because they don't seem to matter.

3) When you can't find the reason and the law, don't act, you can control the influencing factors of the aalysis;

4) Review some of the experiences and rules of previous experiments and summaries;

5) Once you find some experience and laws, go deeper and raise it to theory, even if more waste costs are worthwhile;

6) You must know that "the embankment of a thousand miles is destroyed by the ant nest", you must also know "Yugong Yishan".

4. To establish a preventive thinking

1) The highest level of quality management is prevention, not how to save after a problem has occurred;

2) There must be signs before any quality problems appear, depending on whether you have methods, means and experience to monitor and identify them;

3) The same quality problem should be highly regarded when it is repeated for the second time;

4) The daily process and result data should be sorted out with certain tools, and the rules and trends should be searched from the results of the collation. These rules and trends are constantly revised;

5) The control elements should be as consistent as possible before processing the product.

5. Quality control must have a management mind

1) Do not want to rely directly on the craftsman to achieve product quality stability;

2) The quality of the product is manufactured, it is not managed by the direct manufacturer, and the quality can never be stabilized;

3) Therefore, it is necessary to observe, pay attention to and study the performance and status of the direct manufacturers of the products, and manage and mobilize them according to these performances and states;

4) If the direct manufacturer's performance and status are not controlled, once the quality problem occurs, you will always analyze the cause of the inaccuracy;

5) Do not think that the process control requirements specified in our current process discipline are met, and the product quality is absolutely no problem;

6) Therefore, our process control requirements must be constantly improved, and we must also manage people.

6. Listen to comments and suggestions

1) Don't think that others don't know the actual situation, can't solve the problem all at once, and the opinions have no value;

2) But they, especially the direct manufacturers of the products, can give us a lot of tips and reminders;

3) If you can solve this problem, your opinions and suggestions can not be heard; but when you are uncertain, it is recommended that anyone's opinions and suggestions should be heard, and should be tried and tested, whether you agree or disagree;

4) The thinking of quality management often touches the forefront of technology, even if it is a casual sentence or a complaint, it may guide or imply a major technological innovation direction, so professional and technical personnel should pay attention to details and be good at capturing details.
