Many Japanese workplaces use 5S, five words that begin with the letter s in Japanese: seiri, seiton, seisō, seiketsu and shitsuke.
A Japanese business glossary defines them in turn. Seiri is separating what is needed from what is not, and getting rid of what is not. Seiton is deciding where and how each thing is kept, so that it is easy to use. Seisō is cleaning, so that work can begin at once. Seiketsu is keeping the first three in place. Shitsuke is making the habit stick.
