Quality assurance refers to all planned and systematic activities implemented in the quality system, and verified according to needs, so as to provide enough trust to show that the enterprise can meet the quality requirements. With the development of production, the division of labor is more and more detailed, and products and services are more and more complicated. When customers accept products and services, it is increasingly difficult to judge whether they meet the requirements.
Therefore, enterprises need to provide customers with evidence to prove that all aspects of their design and production are capable of submitting qualified products or services. These evidences are the products of planned and systematic quality activities. As far as enterprises are concerned, quality assurance can be divided into external quality assurance and internal quality assurance.
External quality assurance is a quality activity that makes customers believe that the products or services provided by enterprises can meet the predetermined quality requirements; Internal quality assurance is a quality activity, which aims to ensure that managers at all levels can meet and maintain the predetermined quality requirements.
In order to provide this kind of trust, it is usually necessary to constantly evaluate and review the relevant elements in the enterprise quality system to prove that the enterprise has the ability to continuously and stably make products or services meet the specified requirements.
