The first step to improve the production site is to separate the needed people, things and things from the unwanted people, things and things, and then deal with the unwanted people, things and things. Its main point is to classify all kinds of articles actually placed and stagnant at the production site, and distinguish between those needed and those not needed at the site; Secondly, we must resolutely clean up unnecessary items on the site, such as used materials, redundant semi-finished products, chips, leftovers, garbage, waste products, redundant tools, scrapped equipment, workers' personal daily necessities, etc. The focus of this work is to resolutely clean up unnecessary things at the scene. The front and rear of each station or equipment in the workshop, the left and right of the passage, the up and down of the workshop, the inside and outside of the toolbox and the dead corner of the workshop should be thoroughly searched and cleaned to make the best use of everything. Resolutely doing this step is the beginning of establishing a good style of work. Some Japanese companies put forward the slogan: efficiency and safety begin with the end! The purpose of trimming is to increase the working area; Smooth logistics to prevent misuse, etc.

Quantify and locate the people, things and things needed. After the completion of the previous step, scientifically and reasonably arrange and place the items that need to be left at the production site, obtain the required items as quickly as possible, and complete the operation under the most effective rules and regulations and the simplest process.
