It is often seen that some people confuse the concepts of QA, QC, and QM and think that they are different descriptions of the same concept, because these three are all from the product, in addition, the translator's understanding of concepts in the translation process is inconsistent, resulting in inconsistent translation quality. I read a lot of information and think the differences between them are as follows:

1. concept:

QA: Quality Assurance (Quality Assurance)
QC: Quality Control)
QM: Quality Manage (Quality Management)

2. Definition:

QA: operating technologies and activities to meet quality requirements
QC: To provide sufficient trust to indicate that the entity can meet quality requirements, all planned and systematic activities carried out as needed
QM: determines the quality policy, objectives and responsibilities, and enables all activities of all management functions implemented through, for example, quality planning, quality control, quality assurance and quality improvement

3. Responsibilities:

QA: The most important responsibility lies in the improvement of the system layer, focusing on the prevention of problems and the exploration of the root causes of existing problems and the implementation of countermeasures, so as to reduce the occurrence of adverse problems.
QC: The most important responsibility is to monitor finished products.
QM: The most important responsibility is to ensure the quality work environment at the organizational level.

4. skill requirements:

QA: qualified QA is a senior talent in the organization. You must have a full understanding of the Process Definition of the Organization and be familiar with the engineering technology used in the participating projects.
QC: includes senior talents such as software testing designers and general testers.
QM: not only QA and QC skills, but also professional management skills

The relationships among QA, QC, and QM are as follows:

In fact, QM and QA are mutually dependent, and all organizations will benefit from the overall benefits of combining QM with external QA, they also provide a joint approach for the management, execution, and verification of various jobs to achieve satisfactory results. Although their activities have different scopes, different purposes, different motivations and different results, their complementarity can make all quality management functions operate effectively, gain internal and external trust.

Quality management includes both quality control and quality assurance, as well as quality policies, quality planning, and quality improvement. Quality management is implemented through the quality system. The quality system includes quality planning, quality control, quality assurance and quality improvement.

Some activities of quality control and quality assurance are interrelated. For example, quality control activities include verification and review, and verification and review are also the validation activities of quality assurance. Quality control focuses on control measures (operating technologies and methods), and quality assurance focuses on validation of control results to provide full trust.

[Three in the software industry]

Compared with the software industry, SQA refers to the product and process assurance personnel to ensure that the quality meets the requirements through the process method; SQC refers to the testing personnel, through the verification method to provide evidence that the product meets the requirements; SQM refers to quality management personnel. Generally, it is responsible for quality managers and creates good environments and conditions for QA and QC work through a series of measures such as process formulation and resource coordination.

Reference "become" chief quality officer"

If quality means an organization's ability to "do things right for the first time", this ability requires three aspects of cultivation: first, "control system ", the second is the "Guarantee System", and the third is the management philosophy. Think about how you drive, and you will probably understand the relationship between quality control, quality assurance, and quality management.

Phillips krausby said: let me clearly express the relationship between quality control (QC), quality assurance (QA) and quality management (QM:

QC is like an instrument on the dial of a car. They measure the state of the car and tell the driver instantly. Therefore, we can see any problem, such as the engine overheating or the speed exceeds the limit. This is very valuable.

QA is like the car user manual we receive. It includes usage information, maintenance programs, and other useful information. ISO 9000 and similar information packages are like such manuals.

QM is the philosophy of driving cars. While those dangerous drivers have the same real-time information and how to drive properly. Because philosophy comes from education.
