Introducing the 5S Methodology - 1
What is 5S?
5S is the name given to a methodology developed in Japan by Toyota for organising, cleaning, developing, and sustaining a productive work environment. The 5S methods, when correctly applied, substantially reduce waste and optimise all aspects of productivity by maintaining an orderly and efficient workplace. 5S is a key element of the Lean Manufacturing methodology.
The 5S name is derived from five Japanese words, which when translated into English, the closest equivalent words start with the letter S. The five functions identified by 5S are known as Pillars.
The 5S Pillars are defined and identified in the following table.

5S is occasionally and incorrectly characterised as a standardised cleanup or a housekeeping methodology. However, this is very misleading because organising a workplace goes way beyond any clean and tidy type philosophy.
In recent times a Sixth S has been introduced by some organisations to help further highlight and drive Safety aspects in the workplace.
