Seiso

Seiso, the third step in "5S", says that 'everyone is a janitor.'  Seiso consists of cleaning up the workplace and giving it a 'shine'.  Cleaning must be done by everyone in the organization, from operators to managers. It would be a good idea to have every area of the workplace assigned to a person or group of persons for cleaning. No area should be left uncleaned. Everyone should see the 'workplace' through the eyes of a visitor - always thinking if it is clean enough to make a good impression.

Seiketsu

The fourth step of "5S", or seiketsu, more or less translates to 'standardized clean-up'. It consists of defining the standards by which personnel must measure and maintain 'cleanliness'.  Seiketsu encompasses both personal and environmental cleanliness. Personnel must therefore practice 'seiketsu' starting with their personal tidiness. Visual management is an important ingredient of seiketsu.  Color-coding and standardized coloration of surroundings are used

for easier visual identification of anomalies in the surroundings. Personnel are trained to detect abnormalities using their five senses and to correct such abnormalities immediately.

Shitsuke

The last step of "5S", Shitsuke, means 'Discipline.' It denotes commitment to maintain orderliness and to practice the first 4 S as a way of life.  The emphasis of shitsuke is elimination of bad habits and constant practice of good ones.  Once true shitsuke is achieved, personnel voluntarily observe cleanliness and orderliness at all times, without having to be reminded by management.
