The 5S system is a lean manufacturing tool it describes how the work can be performed efficiently, effectively, and safely. There are five steps in the system, each starting with the letter “S”. The principles of 5S originated from five Japanese words: (Seiri), (Seiton), (Seiso), (Seiketsu), (Shitsuke), which have been translated into English roughly as ‘Sort’, ‘Set in Order’, ‘Shine’, ‘Standardize’, and ‘Sustain’.5S was developed in Japan So that it is also known as the Japanese concept of “FIVE-S”.
