There are many companies, once the quality problems, the responsibility to the quality department, think that this is the responsibility of the quality department, because they all have such a point of view:
It is inevitable to allow a small number of defects and unexpected defects.
Quality is the responsibility of the quality management department.
Only pay attention to the inspection of the products, and the inspectors should be responsible for solving the defective products.
The problem is that the quality department is concerned.
I think a lot of friends who do quality work have more or less felt this way. When the report is often written, the quality department is done by one person, the other departments do not care basically; the boss thinks the quality is not very important, the research and development is very important, making money is the most important. Therefore, the quality department does not have any position in the company, often speaking a few truth, it should be a flash.
Then, is the product quality produced or checked out?
First of all, we need to analyze the relationship between the first and the latter, the initiative and the passive. As we all know, product production in the front, after inspection, in other words, only a gentleman produces products, can be tested, if there is no product will not be tested, what is the result of the advantages and disadvantages?
Obviously, production is active and inspection is passive. Before the concept of "product quality is produced, not tested", early quality management is limited to quality inspection, only the quality of the product can be checked afterwards.
William Deming's famous quotas point out that the quality of the product can be guaranteed only in every part of the production process and in strict accordance with the requirements of the production process and the work instruction. If the process control is ignored, it is impossible to guarantee the quality of the product only by inspection, because the quality inspection can only eliminate the defective products and waste products, and the quality of the products can not be improved. That is to say, the key point of quality control must not be placed on the post check, but must be placed in the manufacturing stage, that is, the production stage.
Why is there a quality problem?
Before the product development, the problem is not handled well, the rate of direct through production is too low, we hope to rely on the quality to save the fire, to improve the detection frequency, to reduce the defective products or unqualified products; to join the material and unqualified material, there is no prior test verification, no accurate product quality fluctuation cognition; customers urge the goods to be goods. Under pressure, the boss will speak according to his own practical experience, carry out special release for products that are not in the standard range, lead to product problems; the industry has raised the quality standard of the product, the company still produces the product according to the original standard; the quality problem of the nonhuman being in the production process is not examined. In the range of frequency measurement and so on...
A real case of quality
A car accessories, using a company's ABS (750SQ), after 3.4 tons, found that the raw material made of the raw materials have black spots on the surface, resulting in unqualified products, resulting in a huge loss.
A company produces white film for milk film, all the testing items are qualified, so the method is out of the factory, but when the film manufacturer uses it, it finds that the taste of the mother grain is more difficult, and then the complaint is made. Finally, hundreds of tons of orders were created because of such a quality problem. Fortunately, the users did not produce the films, otherwise the consequences would be really unthinkable.
The engineering masterbatch produced by a company, which is not strict in color control, causes the use of the plastic products produced by the company to produce chromatic aberration, which causes the customers to no longer use the company's plastic products.
Because the control of plastic water is not strict, the plastic business in the use of plastic process, plastic various bubbles, resulting in a large number of unqualified products, the last dozens of tons of plastic, all returned, and compensation for the loss.
There are many cases of plastic quality. If the quality departments are going to take the lead, it is really unfair. The author believes that quality control needs to be controlled in every link of the quality management system, which is obviously not fully undertaken by the quality inspection department or the quality management department, and must be carried out by the people in the best position. For example, the quality problem of some products is easy to find in the production process, but it is difficult to find out in the test. At this time, the producer is obviously more aware of the quality problem than the quality inspector. If the practitioners do not control the quality actively and only rely on the quality inspector, the quality of the product will not be fundamentally guaranteed.
How to control the quality of the product omni-directional
The product is basically located at the design stage, and the quality of the product is guaranteed by purchasing, processing, packing and transportation. The control of these links is good, and the quality is naturally controlled. Therefore, the quality of products is realized in the process of design and production, and the quality is achieved through process management. How to control the quality of the product:
First, setting up quality is the lifeblood consciousness of the enterprise
To realize that the quality of the product is not good, the product has no market, the product has no market, the enterprise will lose the source of profit, the time is long, the enterprise will go bankrupt, and the employee is unemployed. Of course, for the company, even if the product market is good, but also must "be vigilant in times of danger", make the product quality better, and create a better corporate reputation. As the saying goes, "if you are in full bloom, the wind comes in."
Second, set up the quality of customer consciousness
All take the customer as the center, regard oneself as the customer, regard oneself as the operator of the next process, regard oneself as the consumer of the product. In this way, the work will be conscientiously done in the middle of the work, we all do the job well, the quality of the product will have a guarantee, if in the work of stealing material, the harm will be their own interests.
Third, set up the consciousness of the quality of prevention
"The quality of the product is produced and designed, not by inspection, but at the very first time." This is not a slogan, which reflects the preventive quality of product well. If the quality control does not start from the source, it will be very difficult to control the quality of the product.
The cost of the product will be greatly improved, even if a large amount of inspection manpower is put into the production, and the production of a large number of defective products or even waste products produced by the production is not controlled from the source. Moreover, some of the quality problems of the products may not be found and remedied from the post process, which requires us to do things well in the first time to prevent the quality of the problem.
Fourth, set up the awareness of the quality of the program
Quality management is the whole process and the whole company, and between the various processes, the work between the various departments of the company must be orderly and effective. All the quality managers and operators are required to be done strictly in accordance with the procedures. If the chances are not to go wrong according to the procedure, the quality of the products can not be guaranteed.
Fifth, set up the sense of responsibility for quality
80% of the quality problems are management, and only 20% of the problems originate in the staff, that is to say, the manager's controllable defect accounts for about 80%, and the operator's controllable defect is generally less than 20%. While improving the management level, managers must make the operators understand the following four points:
A. the operator knows what he does and why he does so.
B. the operator knows whether the product he has produced meets the requirements of the specification.
The C. operator knows what the consequences will be if the product he does not meet the specifications.
D. operators have the ability to handle abnormal situations correctly.
If the above four points have been met and the equipment, tooling, testing and material conditions are all available in the production and the failure still occurs, it is considered to be the operator's controllable defect. If any of the above four points can not be satisfied or the material conditions such as equipment, tooling, inspection and material in production are not available Failure is the responsibility of managers. Only by understanding the responsibility of quality problems can we improve the quality of the problem and improve the quality.
Sixth, set up the consciousness of continuous transmission of quality
Quality is not the best, only better. Quality improvement is a continuous and continuous process. It follows the PDCA mode. The PDCA model can be summarized as follows:
P - plan: make improvement plan according to the requirement of the product;
D - Implementation: implementation plan;
C inspection: inspection of processes and products according to product requirements;
A disposal: take measures to continuously improve product quality.
Only in this way, will the quality of our products continue to rise. Only in this way can we constantly improve the quality and innovation, so that we will continue to win better than the market.
Seventh, set up the cost consciousness of quality (i.e. quality standard consciousness).
Ensuring quality and pursuing profits is the eternal goal of an enterprise. If the enterprise wants to develop, it has to pay attention to the cost of production, but the cost and quality are closely related, the quality is well done, the cost of the product can be reduced to the lowest. If the quality of the product is not good, the customer often returns the complaint, then his cost will be high, and even the enterprise will be forced to the end. Many of the reasons for the decline of enterprises: not because there is no customer, no order, but because the internal management of the enterprise is not good, the cost will not come down and can not participate in the market competition, the enterprise should take it as a warning.
But the better the quality is not, the more favorable to the enterprise. On the contrary, excessive improvement of product quality will result in excess quality and increase production costs. So when we are in production, we need to do all the procedures and links in strict accordance with the requirements of the customer standard. In this way, we will reduce the cost to the maximum and improve the competitive advantage of the market.
Eighth, set up the quality of education consciousness
With the development of the times, the concept of quality management is constantly updated and needs learning. The successful enterprises in twenty-first Century will belong to those learning and growing enterprises, strengthen the internal training and improve the creative ability of the whole staff, which will make the enterprises thriving and changing with each passing day. Therefore, "quality begins with education, and finally education." It has been proved that the successful enterprises are strictly producing the product according to the idea that "the product is produced". They strictly keep every link of the product production to ensure that the quality of every link is not wrong, and that the product is a good product, so that the product can stand the market. Test.
