What is the difference between quality control and quality inspection, and what is the basis for qua

1. Differences in the nature of work: quality control: supervision, inspection, follow-up, statistics, analysis, correction and prevention, standardization; Quality inspection: inspection, feedback, labeling, follow-up, supervision.

2. The difference between the supervision object: quality control: the inspection method of the supervision inspector and the operation method of the operator; Quality inspection: supervise the operation methods of operators.

3. The difference in follow-up: quality control: follow-up long-term measures to improve the effect; Quality inspection: follow up on the rectification results of temporary measures.

4. The difference in problem handling: quality control: analyze and solve problems to prevent recurrence; Quality inspection: find feedback problems and identify them.

5. Functional differences: quality control: planning and execution; Quality inspection: Execution.

6. The difference in work characteristics: quality control: management-based, supplemented by inspection; Quality inspection: mainly inspection.

Their work is aimed at product quality assurance, so many companies' quality departments are called quality assurance departments.

Quality control, quality management, use systematic quality management tools to ensure the stability of the production process and prevent the occurrence of defects, such as using standardized operations to prevent man-made defects: the establishment of inspection standards, the issuance of standards, the provisions of operating methods, etc. (process flow chart, potential effectiveness model after the consequences analysis, control plan); Use statistical methods to find out the causes of defects, analyze and take preventive and corrective measures to prevent recurrence (8D report); Use statistical methods to control the stability of process capability SPC; And so on and so forth.

The inspector is mainly to eliminate defects; Quality engineers are mainly responsible for preventing defects.

In a literal sense: quality control --- related to quality management, and quality inspection --- work to inspect product quality.

From the general concept: quality control is quality management, including quality verification at the time of design, product testing at the time of trial production, quality inspection at the time of mass production, after-sales quality service and so on. Its job functions run through the various stages of the product; The work of quality inspection is only for the inspection of product quality, so the scope of work is narrower than that of quality control personnel.

The above is for reference.

Quality control refers to a quality-centered, full-staff participation-based management approach that aims to achieve long-term success through customer satisfaction.

Only with the consent of the buyer can the enterprise obtain certain benefits. In order to achieve this, we must manufacture a management system that meets the quality requirements of our customers in a correct and economical manner, such as the indispensable production and sales technology and the technology to ensure product quality.

In pursuit of efficiency and improved working methods in all work, it is necessary to solve a wide variety of problems that arise in the work and to always explore new and more effective methods. Such activities are called quality control. And will"Quality control in manufacturing"As a key narrative.

Transactional work, as mentioned earlier, also has a lot in common.

In various production industries, the main work content of quality management is generally done:

1. Participate in the research and development and trial production of products.

2. Put forward suggestions or suggestions for improvement on the specifications and operating standards of products, raw materials, processed products, etc.

3. Formulate inspection standards for incoming materials, processed products and finished products.

4. Formulate process inspection standards and check whether the inspection personnel at the inspection station are indeed implemented.

5. Proper disposal of abnormal quality and identification of scrapped products.

6. Management and calibration of inspection instruments and gauges, and sampling inspection of inventory.

7. Sorting and evaluation of the delivery quality performance of raw material suppliers and outsourcing processing manufacturers.

8. Supervise and assist cooperative manufacturers to improve quality and establish a quality management system.

9. Process inspection.

10. Process management and analysis, project research and improvement, prevention and other re-issuance prevention measures.

11. Analysis, inspection and improvement measures of customer complaints and sales returns.

12. Feedback the information to the relevant units.

13. Carry out daily inspection of quality management.

14. Do a good job in quality assurance.

15. Research, formulate and implement quality management education and training plans.

16. Formulate quality management regulations and implement total quality management.

17. Other related quality management matters.

Quality management is quality control, with two abbreviated prefixes, called QC.

There may be many people who think that quality control is to determine whether a product is good or bad, and that it is a job to inspect products. But quality control in the true sense is not like that, but the work of all employees, and the improvement of the quality of all work.

Only with the consent of the buyer can the enterprise obtain certain benefits. For this reason, we cannot lack the indispensable technology of production and sales, and the technology to ensure the quality of products"We have a system of means to economically manufacture products that meet the quality requirements of our customers"。Therefore, as mentioned above, it is necessary to pursue ways to improve the efficiency of all work and effective work, and therefore to solve the various problems that arise in the work, and to always explore new and more effective methods.

Such an activity is called:"Problem solving"Various techniques are being developed as a solution to the problem. This technique and the preliminary perspective of quality management will be learned in this lecture、And will"Quality control in manufacturing"As a key narrative. Transactional work, as mentioned earlier, also has a lot in common.

It is the branches and leaves that go in and come out, and it is furniture that sells well all over the country.

Quality management refers to the coordinated activities of directing and controlling the organization in terms of quality. Command and control activities in the area of quality usually include the formulation of quality policies and objectives, as well as quality planning, quality control, quality assurance and quality improvement.

Summary. 1. Formal inspection standards;

2. Samples. Note: A formal and complete inspection standard will generally contain drawings, test items, testing methods, testing tools, sampling methods, sampling timing and regulatory requirements;

In general, the role of the sample is mainly to control the appearance, because the appearance is more difficult to describe clearly with words.
