What is QC, what does QC mean?

QC is the abbreviation of English quality control, Chinese meaning is quality control, its definition in ISO8402:1994 is "the operation technology and activities taken to meet the quality requirements".

It is the most basic requirement of quality management for products to be shipped after inspection. Quality control is done to eliminate the factors that cause non-conforming or unsatisfactory results at all stages of the quality loop by monitoring the quality formation process. In order to meet the quality requirements and obtain economic benefits, various quality operation technologies and activities are adopted.

In the enterprise field, quality control activities are mainly the management of the production site within the enterprise, which has nothing to do with whether there is a contract or not, and refers to the activities of technical measures and management measures to achieve and maintain quality. Quality inspection is subordinate to quality control and is an important activity of quality control.

Some organizations that implement ISO9000 will set up such a department or position, responsible for the quality control functions required by the ISO9000 standard, and the personnel who hold this kind of work are called QC personnel, which are equivalent to product inspectors in general enterprises, including incoming inspectors (IQC), process inspectors (IPQC) and final inspectors (FQC). The most important responsibility of QC is to monitor the finished products (mainly including raw material, in-process goods, finish goods, in-process audit), focusing on detecting defects through sample inspection. The specific requirements of each company for this kind of position will also deviate slightly.

The old seven methods of QC refer to: checklist, layer method, plato, cause and effect map, scatter chart, histogram, and control chart.

The implementation of the seven major methods of QC shows the advanced degree of the company's management to a certain extent. The success or failure of the application of these methods will become an important aspect of the company's market upgrade: almost all OEM customers will take the application of statistical technology as an important aspect of the audit, such as TDI, Motorola, etc.

QC team refers to the quality management team, is a mass, in order to improve product quality, improve process quality, service quality, improve the environment, reduce costs, etc., the use of P--D--C--A cycle law to deal with problems for the purpose of composition, can make a department can also be joint related professions and units, sometimes can also need leaders to participate.

To put it simply, it can be understood as a small innovation and a small invention of the project.

First, QC is to do: quality control, so that it meets the standard requirements; Meaning: "quality control".

Second, QC is the abbreviation of English quality control, Chinese "quality control".

Third, the work of QC:

QC's work is mainly the inspection of finished products, raw and auxiliary materials, etc., and QC is a quality assurance for the whole company, including the release of finished products, raw and auxiliary materials, and the quality management system.

normal operation, etc.

In the history of quality management development, "QC" first appeared, and it is the most basic requirement of quality management for products to be shipped after inspection. The QC function is to control the production and processing process and the statistical analysis of process data, and provide relevant information to other departments.

QC is to do quality inspection, divided into four categories, namely:

1. FQC: that is, the final quality control, which is to inspect the quality of the product after completing all the processes or processes of the product.

2. IQC: that is, the quality control of incoming materials, which is to confirm the quality of the materials or products purchased to reduce the quality cost.

Achieve effective control.

3. IPQC: that is, process quality control, which is the quality control of products from production to packaging, also known as inspection.

4. OQC: that is, shipment quality control, which is a comprehensive inspection and confirmation of the product to ensure that the customer receives the goods in accordance with the agreed content.

QC is the abbreviation of English Quality Control, Chinese translated as "quality control". The definition of quality control is: "quality management."

is committed to meeting quality requirements".

The personnel engaged in inspection work are collectively referred to as QC (abbreviation for Quality Controller). cr ma mi stands for:

1. Critical (CR) fatal defects: defects that may cause potential harm to the human body or violate laws and regulations. Such as sharp edges, sharp angles, leakage, etc. (usually, the barcode problem will be defined as CR), products with CE certification are required to have no CE mark due to EU requirements, etc.

2. Major (ma) main defects: some important functional or appearance defects on the product, such as insulated cups without insulated cores, poor logo printing, etc.

3. Minor defects: minor appearance defects on the product, such as small scratches and slight printing defects on the surface of the product.

The personnel engaged in inspection work are collectively referred to as QC (abbreviation for Quality Controller).

1、critical（cr.Fatal defect: A defect that causes potential harm to the human body or a violation of laws and regulations.

Such as sharp edges, acute angles, electrical leakage, bright spikes, etc. (usually, the barcode problem will be defined as cr..)）；CE certified products are required to go out of the EU, and there is no CE mark, etc.

2、major（ma.Major defects: Some important functional or cosmetic defects on the product.

For example, the thermos cup is not insulated, the logo is poorly printed, etc.

3、minor（mi.Minor defects: Minor cosmetic defects on the product, etc.

Such as slight scratches on the surface of the product, slight printing defects, etc.

The full name of QC is QualityControl, which is the person responsible for inspecting products and controlling quality. QC's work is mainly the inspection of finished products, raw and auxiliary materials, etc., and QA is a quality assurance for the whole company, including the release of finished products, raw and auxiliary materials, and the normal operation of the quality management system. Quality control in ISO8402:

In 1994, it was defined as "the techniques and activities taken to meet the quality requirements".

Quality Control (QC): Operational techniques and activities used to meet quality requirements. In order to understand "quality control", we should understand how to meet the quality requirements, that is, "suitability for use".

In order to achieve this ever-changing "suitability for use", it is the responsibility of all levels to maintain quality and to be accountable for a given action.

Evolution. 1. Operator control stage: the quality of product quality is controlled by the operator alone. 2. The team leader control stage: the team leader is responsible for the product quality control of the entire team.

3. Inspector control stage: set up full-time quality inspectors to be responsible for product quality control. 4. Statistical control stage:

The use of statistical methods to control product quality is a major breakthrough in quality control technology and creates a new situation in quality control. 5. Total Quality Management (TQC): quality control of the whole process.
