4S

4S stands for

SEI-LI = Organization
SEI-TON = Orderliness
SEI-KEZ = Neatness
SEI-SOU = Cleanliness

4S originated from the Chinese but has been successfully implemented by the Japanese. 4S takes a bottom-up approach compared to other quality improvement concepts which normally takes a top-down approach.

To put 4S in a simple manner "Organize your materials. Perform the job in an orderly manner. Cleanup afterwards." The 4S approach is more gear to the individual (more personal), getting the individual to be more orderly and organized.

"Nothing is particularly hard if you divide it into small jobs."

Henry Ford
