2. Understand the necessary professional knowledge and requirements at home and abroad, and master the processing principle and technical requirements of products.
3, familiar with the product technology and quality requirements of each working procedure, process supervision, timely find problems, preliminary analysis of problems, communicate with the production department to solve problems, sum up experiences and lessons to prevent problems from happening again.
4. Be familiar with the process quality requirements within the scope of responsibilities, and conduct inspection in strict accordance with the inspection instructions (raw materials, semi-finished products, finished products, inventory products, shipment supervision, installation sampling).
5. 5S supervision and maintenance.
6. Implementation and revision of technical documents, audit of quality records, and filling in the ex-factory inspection report, etc.
7. The three principles of quality work: do not accept unqualified products, do not manufacture unqualified products, and do not deliver unqualified products.
Do not accept unqualified products: do not accept the defects of raw materials, and the defects of the previous process will not be accepted in the next process;
Do not manufacture unqualified products: do a good job in process control;
Do not manufacture unqualified products: the last process does not export defective products to the next process, and does not export defective products to customers.
8. Principle of not letting go of quality problems: don't let go if you can't find the cause of the problem, don't let go if you can't find the person responsible for the problem, don't let go if you haven't dealt with the problem, and don't let go if you haven't solved the problem.
9. Non-concession principle for quality problems: No concession for malicious violation of process, no concession for unauthorized adjustment of process and formula, no concession for malicious obstruction of quality management, no concession for concealing, stealing and using unqualified products, and no concession for malicious destruction or forgery.
Second, a reasonable workflow.
1, sort out your work-specify the work to be done and record it at any time.
2. Procedural work-make a work plan and decompose the work to be done.
Follow the rules-execute the work plan.
Confirm the end of the work-check the implementation
Record after confirmation-ensure traceability.
Review procedures for improvement-continuous improvement can be continuous improvement.
Third, professional mentality.
On the one hand, we should cooperate with the requirements of the production department to complete the production task with good quality and quantity; On the other hand, as the site manager of quality control, he should reflect the situation in the production process to his superiors and play the role of "scout". How to correctly position the relationship between yourself and the enterprise is for reference only:
1. Work with passion and take it as your own career.
It is the most taboo for enterprises to regard enterprises as hitchhiking or springboard and hold employees with the mentality that their owners can't change their homes. People are the foundation of enterprise development. Only when enterprises are regarded as a stage to display their ambitions and a place to learn and improve themselves can enterprises grow and develop, and individuals will be good if enterprises are good. We should put all our enthusiasm into our work, actively participate in management and seek common development with enterprises.
Any enterprise wants employees to have a positive, enthusiastic and serious attitude towards their work. Because only such employees are the foundation of enterprise progress. Passionate employees can infect others' emotions and make things develop in a good direction. Enthusiasm for work can promote the improvement of working ability. With work enthusiasm, you can enrich your work results and prove your work ability. If you have no enthusiasm for your work, you will only get depressed day by day.
2, constantly improve their ability in the work, don't rely on a certain enterprise.
Enterprises hire every employee in the hope that he can create greater profits for the enterprise. When an employee can't create profits for the enterprise, he loses the use value, which is a cruel reality.
Therefore, we must understand that enterprises are not shelters. Working hard and improving our ability in the work is the foundation for us to settle down.
It is our duty to work hard to make our work more valuable, make greater contributions to the enterprise and meet the company's requirements for employees. On the other hand, if enterprises are really like shelters, they won't keep people away, everyone has food and everyone is happy, then we should be careful instead.
3. Doing a good job is the basis of establishing labor relations with enterprises.
Only when enterprises make profits can they survive and develop. If every employee wants to make himself more valuable, he must first create more considerable "value" for the enterprise. It is only self-defeating for employees to bargain with the enterprise when the work is not done well or the results are not yet seen. Because the enterprise is not a welfare home, every copper coin paid must have a good reason.
Fourth, the job requirements for quality control personnel
1, basic quality
Do you love your job? Love the scene, often patrol the scene, be able to think positively, have a sense of responsibility to consumers, be diligent and innovative.
Keep an insight into things and be sensitive to problems, and focus on finding problems, such as working environment: floor-wall-doors and windows-ceiling-lighting facilities-ventilation and exhaust facilities-cooling facilities-water supply and drainage facilities?
2, job requirements
Report voluntarily. ?
Actively learn business knowledge and management methods. ?
Lead by example, take the initiative to pick up the garbage on the ground, help employees tidy up tools and instruments, and tidy up work clothes and hats that do not meet the requirements. ?
Put all your enthusiasm and strength into your work, and you can't: it's important to say it, it's secondary to do it, and you don't want to be busy. ?
Change ideas and keep pace with the times. The work style and content of the new post will be very different from that of the old post, and this change will happen to everyone. We need to change ourselves and accept new attitudes, new values and new world views. Know what your role is and how to get into it. Adjusting yourself as soon as possible and adapting yourself to the new post is a major aspect of the transformation. ?
3. Observation ability
If in doubt, we should check it. ?

housekeeping
First of all, the source of bad variation
1, the source of variation
One of the sources of variation is machines.
Such as: whether the beater works normally, whether the sealing machine works normally, whether the nitrogen filling machine works normally, whether the ozone generator works normally, whether the nozzle for spray cleaning is unobstructed and whether the water pressure is normal.
The second substance of the source of variation
Such as: supplier changes materials, material changes, specification changes, quality changes.
The third method of variation source
Such as: the process execution is not in place, the operation process changes, the operation method changes, and the tools and equipment are improperly used.
The fourth person comes from the source of variation.
Such as: the proficiency of employees, their habits, whether employees work according to standards (no training, poor training effect, understanding but not implementing), their physical strength and emotions (different due to different working hours).
The fifth source of variation is environmental factors.
Such as: cleanliness and status of floors, walls and ceilings, status and illuminance of lighting facilities, status and effect of ventilation and exhaust facilities (condensed water and air quality), status and effect of temperature control (wet) facilities, status and effect of water supply and drainage facilities (temperature and humidity), water quality, cleanliness of workplaces, placement of articles in workplaces (5S) and implementation of SSOP (sanitary status).
The sixth management factor of change source
Such as: urgent orders, special varieties, frequent product replacement, too long overtime, frequent turnover of personnel, and the level and quality of management personnel.
2. Classification of variation
(1) recurring problems
This kind of problem belongs to system problems, such as environmental factors and management factors. If many process parameters have a floating range, this floating is inevitable, but the difference in product quality within this range is acceptable.
② Occasional problems
If the whole package of raw materials is unqualified and the packaging machine is not timely, new employees or individual employees will cut corners. This type of variation should be found if you pay attention to observation, and it is also the source of product instability, which can be controlled through management.
Second, the main points of preventing defective products
1, stable personnel
Imagine that a new employee is inefficient not only because of poor proficiency, but also because he is unfamiliar with the working environment, machines and processes, materials, working methods, product quality requirements and quality awareness. How can we ensure the stable quality of the products they process?
2. Good education and training
In order to complete the work more efficiently and with higher quality, it is necessary for every employee in the enterprise to receive continuing education and training.
3. Establish standardization
Standardization can also be said to be a system, or a regulation, or a working rule, or a working method, which is a regulation to ensure the orderly repetition of one or more tasks. ?
The function of standardization is mainly to store the accumulated technical experience of enterprise members in the form of documents; The whole technology will not be lost because of the flow of people. And because of standardization, every job is operated by different people, and there will be no big difference because of different people. ?
Establishing work standards is the most thorough work to maintain work stability and thus stabilize quality. ?
4. Good execution.
We see that many companies have perfect quality manuals, procedure documents, third-tier documents and various systems, but these documents are only for certification and inspection, and they are not implemented at all or not fully in actual production activities.
Or the top of the enterprise is right, but the actual situation at the grassroots level is not like this at all. The concept of high-level management can't go deep into the grassroots. Even if the standard is perfect, it is difficult to ensure the work effect without execution.
5. Eliminate the dirty environment.
A dirty workplace represents inefficiency, unstable quality and all kinds of waste. ?
The best way to eliminate mess is to carry out "5S activities". ?
Dirty is not an absolute factor affecting quality, but from practical examples, we have to believe that there is a significant causal relationship between the two. ?
6. Collect field data and analyze the source of variation.
Counting the defective products produced in the production line every day is one of the tasks of collecting quality information, as an important means to judge whether the process is controlled. ?
7. Stable raw material suppliers
No matter how good the technology is, no matter how good the machinery and equipment are, it is still difficult to produce good and stable products without good and stable raw materials. Frequently changing suppliers, or blindly pursuing the way of lowering the purchase price to reduce costs, the raw materials are inconsistent, and of course the quality will not be stable.
8, perfect equipment and facilities maintenance system
Products are produced by machines, which have precision and long service life. Machines are just like human bodies, so we should pay attention to maintenance at ordinary times. If the body is not maintained, it will be poor. Similarly, if the machine is not maintained, the accuracy and service life of the machine will be reduced, and even if there is a fault in production, the quality of the product can not be guaranteed.
Third, how to solve the problem.
The correct one should be management. To do a good job in quality management, we must first solve the problems caused by various variations in production reasonably and effectively. How to grasp and solve the problem? ?
1, look at the problem from a global perspective
When grasping the problem, we must observe the whole to determine our position, so that the measures taken meet the overall requirements. To do this, we must know the truth and key points, observe them systematically, trace back to the causes of the problem and think about the root of the problem. ?
2. Look at the essence through the phenomenon and find the root of the problem.
Finding the cause of the problem is the key to solving the problem. If the cause is wrong, the corrective measures cannot be effective. ?
3. Reflect on working methods.
Observe the results of the work and always think positively about whether the current practice is appropriate or not. Don't repeat the same failure, sum up the reasons for the failure and take measures to prevent the same mistake. ?
From attaching importance to results to attaching importance to process. ?
Bad methods will produce bad results. If we only pay attention to the result, but not to the process and method, the problem will come back again. You should learn to analyze from the process of producing bad problems and find out the solutions. ?
From focusing on accountability to focusing on reviewing reasons. ?
If there are bad results, we must investigate the responsibility. "Who didn't do well" must be done from the perspective of clear rewards and punishments, but we should further review "Why?" Pay attention to the cause review, find out the preventive countermeasures, and eliminate the bad factors from the source of the problem (management level). ?
4. Stand in the position of others.
Consider problems from the other side's standpoint, pay attention to overall coordination, and take corresponding actions and improvements.
5. The next process is the customer.
In the whole workflow, we should consider who is your downline, that is, who is your customer, and which one is downline.
Problem warning record
The problem of terminal is the problem of leadership; ?
No problem is the biggest problem; ?
The recurring problem is attitude; ?
It's not your responsibility for the low quality of subordinates.
But it is your responsibility not to improve the quality of your subordinates.
Four, several provisions of the site management
Knowing the site and keeping close contact with the site is an important part of the quality controller's work, and should be able to do the following:
When there is a problem (abnormality), you should get to the scene as soon as possible?
Check the relevant objects and ask the parties and relevant personnel for information?
Take temporary measures on the spot?
Find out the real reason and eliminate it?
Standardize to prevent recurrence?
Whenever there is a problem or abnormal situation, the quality controller will go to the site for inspection. When checking the situation on the spot, he repeatedly asked, "Why? ..... "And using common sense and low-cost methods, we should be able to find out the cause of the problem, without those sophisticated technologies. ?
Improvement begins with identifying the problem. Once you know it clearly, you are halfway there. One of the jobs of quality control personnel is to always pay attention to the site and determine the problems according to the principles of the site and the present. Many problems can be solved quickly by using the principle of on-site objects and common sense. Take a good look at the scene of the problem and make up your mind to find out the real cause of the problem. Many problems related to the scene can be solved immediately on the spot.
Once a problem occurs, it must be solved, and it will not happen again for the same reason, especially in large quantities. Once the problem is solved, the new operating procedures must be standardized, and then the PDCA cycle of "standardization-implementation-inspection-disposal" will be carried out, otherwise everyone will be busy putting out fires all day. ?
To find out the cause of the problem, we should pay attention to the concept and thinking of "edge management". ?
Verb (abbreviation of verb) about "edge management"
Sometimes there is a problem, is it difficult to find the reason? Even feel "impossible", is the customer bothering us? ?
-Try to expand the space and scope of thinking and consider the issue of "edge management". ?
The edge is relative. In the past, when the management was not standardized, the quality requirements of customers were not high, and the profit rate of products was high, many problems were blind spots in management. With the standardization of management, the market demand is getting higher and higher, and the profit rate of products is getting lower and lower. Once there is a problem, it will cause huge losses to enterprises, and the voice of enterprises pursuing "zero defect" is getting higher and higher. ?
To achieve "zero defect", we must observe and analyze all links that may affect product quality and safety, and implement comprehensive management. Those "blind spots" that were easily overlooked in the past have become the main reasons for quality and safety problems. ?
Area edge?
Time edge?
Personnel edge?
Process edge?
In short, the concept of edge management comes from total quality management. Due to the standardization of the market and people's attention to food safety and quality, the requirements of officials and customers are getting higher and higher, and the need for certification, some companies and factories are becoming more and more standardized in their daily management, but they have not paid enough attention to the management of some auxiliary areas/special periods/personnel, or even stayed at the original level, which has become the main hidden danger of safety and quality problems. ?
Edge management is not in place. When there are quality problems, we look for the reasons within the scope of normal management, and often have no clue and think that these problems are ridiculous. ?

Seven, standard knowledge
Standard: Standard is a unified regulation of repetitive things and concepts. It is based on the comprehensive achievements of science, technology and practical experience, approved by the competent department after consultation by all parties concerned, and published in a specific form as a guide and basis to follow.
China's standards are divided into four levels: national standards, industry standards, local standards and enterprise standards.
By scope and approval level: national standards, industry standards, local standards and enterprise standards.
Binding according to standards: mandatory standard GB, recommended standard GB/T.
"Mandatory standards must be implemented, and products that do not meet the mandatory standards are prohibited from being produced, sold and imported."
The role of publishing houses in the standard system: basic standards and general standards
The role of standardization objects in the production process: raw material standards, parts standards, technology and process equipment standards, equipment maintenance standards, product standards, inspection and inspection method standards, packaging standards, etc.
According to the nature of standards: technical standards, management standards and working standards.
Implementation of standards: adoption (equivalent adoption, equivalent adoption and non-equivalent adoption), quotation, selection, supplement, matching and improvement.

Enterprise standards shall be formulated by the enterprise, approved and promulgated by the legal representative of the enterprise or the competent leader authorized by the legal representative, and uniformly managed by the department authorized by the legal representative of the enterprise.
Where there are no national standards, industry standards and local standards for products produced by enterprises, enterprise product standards shall be formulated.
In order to improve product quality and promote technological progress, enterprise product standards stricter than international standards, industry standards and local standards are formulated.
Select national standards and industry standards or supplementary standards.
Technical standards in process, tooling, semi-finished products, etc.
Management standards and work standards in production and business activities.
Enterprise product standards shall be filed with local standardization administrative departments and relevant administrative departments within 30 days after approval and promulgation (Technical Supervision Bureau).
