The road to learning continuous improvement principals is constant and dynamic, picking up concepts and the variations of interpretation. During my 30 plus years of studying and practicing scientific management theories, I noticed how ideas get developed, interpreted and communicated, accepted wisdom sounding important but lost in translation, complexity within the details that may not be needed, long string of words some not used in normal conversations.
Unlike other languages, English is full of innuendo. The normal blue collar workforce with its own vernacular when asked to grasp these new concepts struggle to implement them like fish out of water.
As an example to this, I’d like to share what I learned with the Lean concept of 5 S. First I’ll provide my opinion of the English version, then I’ll follow up with the Japanese version. Obviously, this is my account and does not represent the how other companies pass this acumen to their work force, but it’s important to illicit an argument that we as LSS practitioners are targeted effete, contentious and ineffective.
When I learned the five words: Sort, Straighten, Shine, Standardize and Sustain I was not really convinced of the choice of words to convey the true meaning of a lean practice.
To illustrate some of the confusion, I copied the following from the internet that provided definitions to these five simple words.

There’s no denying that the definitions to these words are correct and comprehensive. As a normal person with some vocabulary, our minds sometimes encounter a selection process to apply the correct meaning, sometimes misinterpreting and thereby creating a wrong or misguided result. One thing I can attest is that by attempting to simplify ideas, it oftentimes generates complexity with a never ending barrage of information. One of my co-workers complained, “If this is so lean, why is it so freaking complicated and asked to LEAN the LEAN PROCESS!”
Good point. So in my studies of 5 S, I stumbled upon the Japanese version:
And this is what I found in defining them:
· Seiri. Tidiness – Throw away junk, don’t keep what you don’t need. Rule of thumbs, if you don’t miss trash it, or store it the hell away.
· Seiton. Orderly. Organize for efficiency. Set things in proper places for quick retrieval and storage.
· Seiso. Clean. Everybody’s a janitor. If you see trash on the floor, pick it up, and just don’t stop there, be clean at home, in public and at work!
· Seiketsu. Standardize a routine that maintains the first three concepts (ala Karate Kid. Rule number 1 "Karate for defense only." Rule number 2 "First learn rule number one.")
· Shitsuke. Discipline. Don’t be lazy. Do your job and do it well.
With that example, compare English version of 5 S then the Japanese.
My vote is the Japanese, simple to pass on to rank and file where concepts are easier to remember and implement.
When asked why the English version was used to substitute the Japanese version, I was told because it was simple to remember. I argued back, then why do we continue to use words like Kaizen, Kanban, Muda, Mura and Muri?
My goal in implementing continuous improvement is results with the least amount of words possible. Sometimes using a foreign language provides a clear story to tell than English which I’ve learned so far can be quite complicated. I think the 6 S that we need to implement is SIMPLICITY!!!
