Some organizations that implement ISO9000 will set up such departments or posts to be responsible for the quality assurance functions required by ISO9000 standards, and the personnel who hold such jobs are called QA personnel.
Quality assurance generally refers to two aspects, one is quality control, and the other is quality assurance.
IQC, FQC PQC and QCC are all factories that guarantee product quality. Generally speaking, QC is the on-line quality inspector, QA is the last factory inspector, sampling inspection, QC is the full inspection; And in essence, QC standards are stricter than QA.
QA is actually quality management. Why management? Because QA combines knowledge of management, analysis and testing. The company's R&D progress, the initial standard formulation of product R&D and the later product R&D all need the participation of QA.
QA can effectively control the progress of research and development and the quality of each link. No matter any product, it is based on the premise that it is suitable for people to use. When making design standards in the early stage of the product, QA can look at the product from the perspective of consumers and make the product more humanized. In the design stage, QA becomes a tester to verify whether the quality of each link meets the requirements of design standards. It is best described as "the person in charge is lost, and the person seen by outsiders is clear." QA is this bystander. No product can be perfect. If something goes wrong, the designer can't find it at once, because it is difficult for a single person to complete the whole product design. At this time, QA is an analyst, finding out the problem, saving research and development time and solving unnecessary troubles.
Any company has its own property rights, and QA can protect the company's property rights well. A sound company, QA has great power to control all technical data of the company. No design engineer can give the technical data of the customer company privately, and these management are completed by QA.
