What is 5S?

As a definition, 5S is a method of creating a clean and orderly workplace that exposes waste and makes abnormalities immediately visible. In fact, it is important to realize that 5S is far more than a housekeeping initiative like so many confuse it to be. When we refer to 5S we are generally referring to 5 Japanese words that start with S. They are:

• Seiri which is commonly translated as Sort
• Seiton which means to Set in Order
• Seisou which means to Shine
• Seiketsu which means to Standardize
• Shitsuke which means Sustain

The 5 Steps

1. The first step is Sort. This step basically challenges us to get rid of the things we do not need or use. This can be a very hard step for some people since they like to keep everything they have ever come into contact with. But this type of attitude only leads to clutter and disorganization. So, if we do not need it we need to get rid of it.
2. The second step is Set in Order. So, once we have cleared out the items we do not need we need to straighten up what is left. The mantra of a place for everything and everything in its place fits this step perfectly.
3. The third step is Shine. This is probably the most misunderstood step of all since most assume this step simply means to grab a broom and clean up. While good old fashioned sweeping is definitely important, this step is far more than just cleaning. The main principle behind this step is to clean to inspect. Put another way, if you find yourself sweeping up the same mess day after day you should do your best to eliminate the source of the dirt.
4. The fourth step is Standardize. This step is focused on creating standards so abnormalities are easily recognized. Things like checklists and audits are very helpful.
5. Finally the last step is Sustain. The key to this step is to apply positive tension. In other words, for any improvements to sustain it must be made clear that this is how we intend to operate as a company. With positive tension we identify issues immediately, but with loose or no tension we do not.

Why is 5S Important?

A neat and clean workplace has higher productivity, produces fewer defects, meets deadlines better and is a much safer place to work. Furthermore, 5S is a key building block for most of the Lean tools and concepts used today. As it is said, without 5S, you can indeed forget the rest.
