5S field management method, a modern enterprise management mode, is also called "five principles", namely, sorting (SEIRI), rectifying (SEITON), cleaning (SEIKETSU) and completing (SHITSUKE).

5S originated in Japan and refers to the effective management of production factors such as personnel, machines, materials and methods at the production site. This is a unique management method of Japanese enterprises. 1955, the slogan of Japanese 5S is "Safety begins with sorting and ends with sorting". At that time, only the first two s were implemented, and its purpose was only to ensure the workspace and safety. By 1986, the works of 5S in Japan were gradually published, which had an impact on the whole field management mode and set off a 5S craze.

Japanese enterprises regard 5S movement as the basis of management and implement various quality management methods. After World War II, the quality of products improved rapidly, and the status of an economic power was established. Under the advocacy of Toyota, 5S has played a great role in shaping corporate image, reducing costs, delivering on time, ensuring safe production, highly standardizing, creating a relaxed workplace and improving the site, and has gradually been recognized by management circles in various countries. With the development of world economy, 5S has become a new trend of factory management. 5S is widely used in manufacturing and service industries to improve the environmental quality on site and the way of thinking of employees, so that enterprises can effectively move towards total quality management. It is mainly aimed at the manufacturing industry to carry out corresponding activities on production factors such as materials, equipment and personnel at the production site. According to the needs of further development of enterprises, some enterprises have increased safety on the basis of 5S, forming "6S"; Some enterprises even carry out "12S", but all the changes are due to "5S". For example, in sorting, it is required to eliminate useless things or articles, which can involve saving and safety in a certain sense. Specifically, such as useless garbage lying in a safe passage, this is the content that safety should pay attention to.
