5S is a system for organizing spaces so that work can be performed efficiently, effectively, and safely. This system focuses on putting everything where it belongs and keeping the workplace clean, which makes it easier for people to do their jobs without wasting time or risking injury.
5S methodology has expanded from manufacturing and is now being applied to a wide variety of industries including Health care or pharmaceuticals, Education and Government. it can also be applied to knowledge economy work, with information, software, or media in the place of physical product.
Origin of 5S System :
5S was developed in Japan and was identified as one of the techniques that enabled Just in Time manufacturing.
5S began as part of the Toyota Production System (TPS), the manufacturing method begun by leaders at the Toyota Motor Company in the early and mid-20th century.
This is often accomplished by finding and eliminating waste from production processes.
5S Translation :

Set in order (seiton) :

- Make the workflow smooth and easy.
- Arrange work stations in such a way that all tooling / equipment is in close proximity, in an easy to reach spot and in a logical order adapted to the work performed. Place components according to their uses, with the frequently used components being nearest to the workplace.
- Assign fixed locations for items. Use clear labels, marks or hints so that items are easy to return to the correct location and so that it is easy to spot missing items.
Shine (seiso) :
Seiso is sweeping or cleaning and inspecting the workplace, tools and machinery on a regular basis.

Also translates as “do without being told”.
- Ensure that the 5S approach is followed.
- Organize training sessions.
- Perform regular audits to ensure that all defined standards are being implemented and followed.
- Implement improvements whenever possible. Worker inputs can be very valuable for identifying improvements.
