5S is a five-step program that is done in sequential order. 5S is a series of activities for eliminating waste that contributes to rejections, mistakes and injuries in the workplace. The Japanese factories are so clean that you can eat off the floor. This is simply a matter of pride for the Japanese.
Below are the 5 Japanese words and their meaning:
1S: SEIRI, 2S: SEITON, 3S: SEISO, 4S: SEIKETSU, 5S: SHITSUKE
1S SEIRI ( ORGANIZATION):
To segregate all the unwanted things and eliminate them. Sorting out all the things in the workplace is the first step. Separate what is needed every day to perform the value-added work from what is not used or seldom used. Mark all unnecessary items with red tags from the workplace. Everything that moves should have a red, yellow or green tag.
Red Tag: Allocate a red tag area. Put unnecessary items there. Dispose of them at some frequency with the help of a team that is authorized for disposal.
2S SEITON (NEATNESS):
To arrange the necessary things in order so that they can be easily and quickly accessed. A place for everything and everything in its place. Seiton is tested by how fast you can put items away and retrieve them when needed. Every item in the factory should have a designated place. Define boundaries to identify locations and designated spaces.
3S SEISO (CLEANING):
Seiso is to keep everything neat and clean. The first cleaning will remove dirt and dust, the second will be better and the third cleaning will prepare for painting. All floors & all equipment should be painted. Cleaning should be everyone’s job belonging to his area. Everyone from the CEO to the helper should participate in the cleaning process. Decide what to clean, how to clean, who will clean and how cleaning will be done. Make 5 minutes cleaning a part of each job. This will increase ownership of the work.
