5S activities originated in Japan and are widely implemented in Japanese enterprises. 7S is the abbreviation for sort, streighten, sweep, sanitary, and sentiment. Its specific meaning and implementation emphasis are as follows: finishing is to distinguish clearly between what is not and what is not, and it is the first step to improve the production site.

We must break through the idea of "useful and discard" and challenge traditional concepts such as "hard to do", "losing good waste", and possibly having opportunities to use later.

We often review the concept that everything is essential.

The purpose of finishing is to improve and increase the area of operation: there is no sundries on the spot, the road is unobstructed, the work efficiency is improved, and the mismanagement accidents such as mixing and mixing are eliminated, which helps to reduce inventory and save money.

To rectify the people, things and things that have been sorted out to be quantified and positioned, in short, rectification is the standardization of the methods of placing people and things.

The key to rectification is positioning, fixing products and quantificationally.

With these three points in mind, we can make Kanban and visual management, so as to extract the method of placing things suitable for our enterprises, and then standardize the method.

Cleaning is to thoroughly clean up the surrounding of your work environment, and repair it immediately when the equipment is abnormal, so that it can return to normal.

The key point of cleaning activities is to clean up objects according to the decision, to clean up personnel, to clean up methods, to prepare cleaning appliances, and to implement cleaning steps to achieve real results.

Cleaning activities should follow the following principles: (1) the items that you use, such as equipment, tools, etc., should be cleaned by themselves instead of relying on others, and no special sweeper should be added. (2) cleaning equipment, focusing on the maintenance of equipment, and cleaning equipment should be combined with the inspection and maintenance of the equipment; (3) the purpose of cleaning is to improve. When the abnormal conditions such as oil and water leakage are found during the cleaning process, we must identify the causes and take measures to improve them.

Cleanliness refers to the careful maintenance of the work done after finishing, cleaning up and cleaning, and keeping the scene perfect and optimal.

Cleanliness is the insistence and deepening of the first three activities.

When cleaning activities are implemented, three concepts need to be adhered to: (1) only in clean workplace can produce high efficiency and high quality products; (2) cleanliness is a kind of conscious action; do not only work hard on the surface; (3) cleaning is a work at any time and anywhere, rather than work before and after work.

The main points of cleaning activities are: stick to the principle of "3 no" - that is, do not put unnecessary things, do not mess up, do not dirty; not only items need to be cleaned, workers at the scene also need to be cleaned, workers should not only do physical cleanliness, but also do spiritual cleanliness.

Literacy should strive to improve the quality of personnel, develop the habit and style of strict compliance with rules and regulations. Literacy is the core of 5S activities. Without the improvement of personnel quality, activities can not be carried out smoothly.
