How to carry out quality control
Question 1: How to do quality control well? For enterprises, the process of quality improvement from scientific planning to implementation is very meaningful. Only through strict and scientific quality improvement plan and hard implementation according to the plan and effective control of the quality improvement process can we achieve good results and promote the development of modern enterprises.

First, quality process control based on customer satisfaction.

In the introduction of ISO9004- 4 standard, it is clearly pointed out: "When implementing the quality system, the manager of the organization should ensure that its system can promote continuous quality improvement. Efforts to satisfy customers and achieve continuous quality improvement should be the eternal goal pursued by management at all levels of the organization. " This sentence points out a direction for enterprises to face increasingly fierce market competition. In order to gain a firm foothold in the market competition, enterprises must continuously deepen quality management, and realize continuous quality improvement of products (or services) based on customer satisfaction, so as to gain continuous competitive advantage and remain invincible forever.

The implementation of continuous quality improvement strategy based on customer satisfaction is to make the products (or services) of enterprises close to, reach or even exceed the expectations of customers. Enterprises must investigate and carefully analyze the different quality types of various quality characteristics of products, and then improve the quality of products (or services) accordingly. Enterprises should provide customers with "necessary quality" and "unitary quality", avoid "irrelevant quality" and "reverse quality", and provide products or services with "attractive quality" as far as possible. In the increasingly homogeneous market environment, only enterprises that can provide customers with attractive quality can continue to grow and develop. Due to the variability and subjectivity of customer satisfaction, the quality characteristics of the same product may be different for different customers and at different times. For enterprises, it is a process of continuous quality improvement to make products meet the needs of more customers in the target market as much as possible, and at the same time keep up with the consumption trends of the times and the consumption preferences of end customers.

Second, strengthen employees' awareness of quality improvement.

Enterprises are composed of management, design, supply, production, marketing and other departments. Errors, negligence or defects of any department may have a direct or indirect impact on quality. Therefore, quality improvement is an overall improvement, and the overall optimization can not be separated from the participation of all employees, who are the main body to complete quality improvement. This is something that enterprises must realize.

Three, quality cost management is the core of quality cost control.

According to the traditional view of quality cost, quality cost management is to determine a minimum quality cost point for products, at which the best balance between cost and quality assurance value can be achieved. For modern enterprises, this is a big misunderstanding. Quality not only means saving, but also helps enterprises to create profits. Correctly introducing quality cost management to promote the continuous quality improvement of enterprises can become a major driving force for the success of enterprises, enabling enterprises to obtain strong strategic competitive advantages, high profitability and return on investment. From the evolution of the theoretical model of quality cost, it can be seen that the continuous quality improvement of enterprises can make the cost of enterprises continue to decline. For modern enterprises, continuous quality improvement is not simply to pursue the "flawless" physical performance of products, but to make the products (or services) of enterprises constantly approach, reach or even exceed the expectations of customers. To promote the continuous improvement of enterprise quality, we can start from the following aspects: first, we must constantly study the needs of customers and constantly update the quality objectives; The second is to create a customer-centered quality culture and formulate a systematic quality improvement strategy; The third is to establish an interactive mechanism between enterprise quality improvement and customers.

Fourth, continuously improve quality to improve quality performance.

If an enterprise wants to succeed continuously, it must admit that it needs continuous improvement. Continuous improvement is a kind of cyclic activity to enhance ability, which is based on conscious, planned and systematic quality improvement. To achieve continuous improvement, we must do a good job in the following three aspects:

1. Institutionalize continuous improvement. When planning a quality management system, enterprises must integrate continuous improvement into the whole quality management system as a principle, that is, the principle of continuous improvement is embodied in all documents, processes, procedures, requirements and responsibilities involved in the quality management system, and there should be provisions pointing to continuous improvement. In the enterprise plan, the goal of continuous improvement is implemented in employees' jobs layer by layer, which becomes a part of post quality responsibility. Technical positions, salary and reward systems are linked to employees' continuous quality improvement performance.

2, regular inspection and continuous improvement. Regularly checking the performance of continuous improvement is continuous ... >>

Question 2: How to effectively control the quality? The competition among any enterprises is inseparable from the competition of "product quality". Without excellent product quality, enterprises will eventually disappear in the wave of market economy. As the most difficult and easy problem, product quality often makes suppliers miserable, from returning goods to losing money, to losing customers and closing down. Therefore, how to effectively control the process is the core to ensure and improve product quality, promote enterprise development, win the market and gain profits. First, insufficient attention has been paid to the development of new customers. Because the customer's order volume is relatively large and has development value, it is necessary to do the corresponding order review to determine the production process route and requirements of the trial-produced products. Second, the first inspection and sampling inspection of products were not strictly implemented. The purpose of the first piece inspection is to confirm that the first piece of product has no abnormal quality and put into mass production, so as to prevent the occurrence of defects. Sampling inspection is to determine the stability of the process, further grasp the product quality dynamics through sampling inspection, and make appropriate adjustments to the production process according to its fluctuations, and finally ensure the product quality. Third, the process quality control is unreasonable. The quality control of the produced products is controlled by the production department itself, and the quality is easy to get out of control, and the corresponding supervision and inspection work is not done well.

Question 3: How to carry out quality control Quality control (QC), also known as quality control, is a part of quality management and is committed to meeting quality requirements. [1] One definition of quality control by China National Committee for the Examination and Approval of Scientific and Technical Terminology is: "Planned and systematic activities that must be carried out in order to convince people that the quality of a certain article or service meets the specified requirements."

Supervise the factory to establish and improve the post responsibility system, formulate or revise and strictly implement various operating procedures in time, and abide by production discipline.

Supervise the factory to establish and improve the post responsibility system, formulate or revise and strictly implement various operating procedures in time, and abide by production discipline.

Supervise the factory to make good preparations before production and arrange the production operation plan reasonably.

Supervise the factory to organize equipment maintenance and keep the equipment in good technical condition. The quality standard to be reached by the repaired equipment. To do a good job in tooling, ensure the accuracy and quality of work, clamping, measuring and cutting tools.

Do a good job in quality management of materials and supplies. Strictly check and accept the incoming materials, and the unqualified and unqualified materials can be returned or rejected. Strengthen the storage of materials to prevent damage and deterioration. Improve service quality and ensure timely supply. Where the products are exclusively purchased and underwritten by ministry of materials and equipment, ministry of materials and equipment shall be responsible for the materials and material quality to the end.

transport

Supervise and inspect quality activities with system documents, and try to count all kinds of information. Unqualified factors (unqualified refers to those that do not meet the specified requirements and are divided into unqualified products and unqualified items) will always be found more or less, which is very important.

But what is the nature of the unqualified factors found? If it is generally unqualified, it has little impact on the quality of the final product, and this unqualified factor is relatively easy to correct; If it is serious or systematic, no.

If it is qualified, it will cause great concern, because it will affect the normal operation of the system and make the final product defective or scrapped. Therefore, the supervision and inspection of quality activities should be set up in the quality system in order to eliminate unqualified factors in time.

Organize, find out the reasons, actively take corresponding corrective and preventive measures, thoroughly solve the unqualified factors, and prevent recurrence. When unqualified products are found, it is necessary to control them, and it is required to analyze the original.

Because, by analogy, to prevent the same problem from happening again, this is the corrective measure. On the basis of formulating corrective measures, the factors (people, machines, materials, methods, environment and measurement) that may lead to such nonconformities are defined as constraints.

(system documents, standards, etc. ) to ensure that the fluctuation of these factors does not exceed the scope of constraints, which is the basic content to prevent unqualified. Track and check corrective and preventive measures, and implement closed-loop zeroing management, so as to

And the quality of the production process is improved. Even so, some factors will fluctuate, and it is impossible to fully and accurately understand the reasons for the fluctuations at one time, which requires continuous finding out of the reasons in process monitoring.

Find one, destroy one, and make the fluctuation close to zero.

Urge the factory to improve the packaging quality. Packaging standards should be formulated according to the characteristics of products, and packaging and inspection should be carried out in strict accordance with the standards. Unqualified products must be reworked. We should constantly improve the decoration of our products to make them beautiful and elegant.

Matters needing attention: 1 Carry out quality awareness education and training in an all-round way.

2. Strict technical procedures

3. Reasonable setting of quality control points and torque control points.

4. Establish a smooth quality information channel.

5. Effectively control defective products.

Question 4: How to do a good job in product quality control and establish a perfect quality control system?

Form a complete quality management chain from supplier management to process quality management to customer management, which is interlocking to ensure the quality of products and services from the system. For example, the quality management system is a comprehensive quality management system with full participation, comprehensive control and continuous improvement. Its documented system has a strong binding force, which runs through the whole process of the whole quality system, making all links in the system interlocking, supervising and promoting each other.

Full participation and implementation

In a company, quality problems are closely related to everyone, and the job of quality control department is to prevent and supervise with people from all departments. Including the determination of senior leaders, but also the participation of the company and every employee. Because of its unique influence, the management and its top managers play a decisive role in the smooth implementation of a system. Grassroots employees should firmly establish the management idea of "quality first", strive for perfection, seek more in the good, seek fast in the good, seek province in the good, strictly abide by the operating rules, do a good job of self-inspection and mutual inspection, find problems in time, and inform the next post in time if they find quality problems, so that everyone can ensure good quality and product quality.

Managers in production departments should seriously cultivate the quality awareness of front-line workers, instead of saying that "everyone must pay attention to quality and have quality awareness", and reveal that a small nonconformity in personal work may turn into a huge loss of money for the company, which requires everyone to understand the requirements before doing anything, so that every step can meet the requirements, so as to understand that this is a great contribution to the company's quality management. As producers, people grasp the scale of product quality, which is the main factor affecting quality. Therefore, employees must be aware of the importance of quality ideologically.

Quality control, focusing on prevention.

Prevention itself must be traced back to product development and design. In fact, the quality of a product has been determined by development and design, and the manufacturing process is only the process of realizing product design. It's like blocking a flood. Is it to build dams, shelterbelts and environmental protection before the flood comes? Or wait until the flood hits your door to remedy it? Obviously, the former environmental protection method is more economical and practical. Therefore, before a new product is put into production, it must go through sample, trial production and small batch production, and every link cannot be missed. Only in this way can some potential quality problems affecting production be controlled in the bud, and the process capability can be continuously improved and improved.

Quality culture construction

Quality management always emphasizes everyone's mentality. To do quality work well, we must first have a correct attitude, then do everything well and get rid of "carelessness" in our work, thus forming a quality culture and concept. If people deviate from the quality concept or attitude, the perfect quality system and advanced quality control methods are useless.

Matters needing attention

Quality management mainly depends on our concept and attitude towards quality. When everyone in an enterprise does this, an excellent quality culture will be produced, which is also the ultimate goal of our management.

If I can help you, I hope I can adopt. Thank you!

Question 5: How to do a good job in quality control is not clear in one or two sentences. I suggest you read more books on this subject.

Question 6: How to effectively control the process quality 5. Effectively control defective products. When most small and medium-sized enterprises deal with bad products, they often ignore the effective control means such as bad cause analysis and measures formulation, and the treatment of problems is limited to the implementation and punishment of superficial responsibilities, which leads to the recurrence of the same problems. Therefore, we must adhere to the "three-no-let-go principle" when dealing with problems, that is, if the analysis of bad causes is unclear, we must not let them go; Corrective and preventive measures have not been formulated; Those responsible have not been dealt with and educated.

In short, in the process of quality management, quality inspection is the foundation and process control is the core. Process control always plays an irreplaceable role in quality control and total quality management. Process control breaks the boundaries between original departments, closely links independent departments, and runs through the whole process of production and technology (design process, manufacturing process, auxiliary process and use process). Let enterprise managers and operators really understand that process control is an effective way to ensure product quality, and then upgrade the post-processing and implementation of quality management to process control and management, and then develop to pre-control and prevention. Realize the total quality control in the true sense, and finally improve the quality management of enterprises from product quality control to the whole process quality control, and then form the whole system quality control.

Question 7: How to control project quality For complex IT projects, the investment scale is large, the implementation cycle is long, and there are many risks in the implementation process, so it is very important to track and manage its quality reasonably to ensure that the final result can meet the requirements of enterprises.

IT project management, like other projects, includes planning management, quality management, time management, budget management, personnel management and risk management. (Remaining 1507 words)

Question 8: How to do quality control? Too extensive? I can't say a word or two clearly. Generalization point

1. Strengthen the training of quality awareness, not only for employees, but also for managers.

2. Establish effective and practical quality circle activities (QCC) and instill the concept of total quality management.

3. Establish an effective and practical performance appraisal system.

Question 9: There are many things in quality control. Take a look first. Are the following things useful to you?

A, quality control:

Quality control is a part of quality management and is committed to meeting quality requirements.

Note: Quality control is not inspection, but a process to ensure that the products produced meet the requirements. Quality control includes making standards and measurement results according to quality requirements, judging whether the expected requirements are met, taking measures to remedy quality problems and preventing similar problems from happening again.

Second, the quality control system design

In quality control, it is necessary to make decisions on the process to be controlled, quality checkpoints, inspectors, measurement types and quantities. After these decisions are completed, a complete quality control system is formed.

1, process analysis

All quality management work must start from the process itself. Before quality control, it is necessary to analyze the related process of producing products or services. A big process may include many small processes, and these processes are described and decomposed by flow chart analysis to determine the key links that affect the quality of products or services.

2. Determination of quality inspection points

After determining each process that needs to be controlled, it is necessary to find the key points that need to be measured or tested in each process. There may be many inspection points in a process, but each inspection will increase the cost of products or services, so the inspection should be carried out in the place where quality problems are most likely to occur. Typical detection points include:

(1) Inspection of purchased raw materials or services before production. In order to ensure the smooth progress of the production process, we must first ensure the quality of raw materials or services through inspection. Of course, if the supplier has a quality certificate, this inspection can be exempted. In addition, in JIT (just-in-time production), the inspection of purchased parts is not advocated, and it is considered that this process has no added value and is "waste".

(2) Product inspection in the production process: The typical inspection in the production process is before irreversible operation or high value-added operation. Because once these operations are carried out, the quality will be seriously affected and great losses will be caused. For example, ceramics need to be inspected before sintering. Because once sintered, unqualified products can only be discarded or treated as defective products. For example, products need to be inspected before electroplating or painting to avoid defects being covered up. These operations can be checked by the operator himself. The inspection in production can also judge whether the process is controlled. If the inspection results show that the quality fluctuates greatly, measures should be taken to correct it in time.

(3) Inspection of finished products after production. In order to correct the defects of products before they are delivered to customers, it is necessary to inspect the products before they are put into storage or sent.

3. Inspection method

Next, it is necessary to determine what kind of inspection method should be adopted at each quality control point. Inspection methods are divided into: counting inspection and measurement inspection. Counting test is to test discrete variables such as defect number and unqualified rate; Metrological detection is the measurement of continuous variables such as length, height, weight and strength. In the quality control of production process, what kind of control charts should be considered: the counting control chart of discrete variables and the metering control chart of continuous variables.

4. Check the sample size

There are two ways to determine the inspection quantity: full inspection and sampling inspection. The guiding principle for determining the inspection quantity is to compare the loss caused by unqualified frequency with the inspection cost. Suppose there is a batch of 500 products, the product failure rate is 2%, and the maintenance and compensation cost caused by each unqualified product is 100 yuan. If this batch of products is not inspected, the total loss will be100 *10 =1000 yuan. If the inspection fee of this batch of products is less than 1000 yuan, it should be fully inspected. Of course, there are other factors to consider besides cost. Products involving personal safety need 100% inspection. While sampling inspection is used for destructive inspection.

5, inspection personnel

Inspectors can be determined by the principle of combining operators with full-time inspectors. In 6Sigma management, most inspection tasks are usually completed by operators.

Three, defense and control measures are:

1), strengthen the quality consciousness, improve the sense of responsibility and meticulous work style, and establish the quality responsibility system.

2), strengthen professional skills training, strictly abide by the operating procedures.

3) Strengthen the "three inspections" (self-inspection, mutual inspection and special inspection: first inspection, patrol inspection and final inspection) and establish a quality control mechanism.

4) Improve the process method to reduce the dependence on the operator's attention.

5) Strengthen full-time inspection and appropriately increase inspection frequency.

6) Carry out QC group activities extensively to promote self-improvement and self-improvement ability.

Note: QC team is responsible for enterprise quality management >>

Question 10: How to effectively carry out quality control in the construction process 1 The concept of quality control in the whole process of building engineering construction. The definition of quality control is the operation technology and activities adopted to meet the quality requirements. The process control of engineering project construction quality can be divided into pre-control, in-process control and post-control, in which pre-control is the quality control in the preparation stage before construction, including the quality control of preparation work and the control of factors affecting quality. Process control refers to all aspects of quality control related to the construction process, including the quality control of intermediate products (process products or partial engineering products). Post-event control refers to the quality control of the finished product (unit project or the whole project) and related aspects (such as quality documents). 1.2 Characteristics of quality control of building engineering Because the construction of building engineering involves a wide range, it is an extremely complicated comprehensive process. In addition, the project has the characteristics of fixed location, production flow, different structural types, different quality requirements, different construction methods, large volume, strong integrity, long construction period and great influence by natural conditions. Therefore, the quality of construction projects is more difficult to control than general industrial products, mainly in the following aspects. Such as design, materials, machinery, topography, geology, hydrology, meteorology, construction technology, operation methods, technical measures, management system, etc. , have a direct impact on the quality of construction projects. Secondly, it is easy to produce quality variation.
