Lean and 5S on the production floor
The Japanese method that keeps order and reduces waste
Lean is a way of thinking that is about creating the most value for the customer with the least waste — wasted time, wasted material, unnecessary movements, and errors. One of the most widespread lean tools on the production floor is 5S, a method that originated in Japan and was originally developed as part of the Toyota Production System.
§The Five Steps of 5S
5S covers five steps, which in Danish are often translated as sort, systematise, shine (clean), standardise and secure (maintain). The steps build on each other and must be repeated continuously — 5S is not a one-off cleanup but a permanent routine.
| Step | What it means |
|---|---|
| 1. Sorting | Remove what you don't use regularly from the work area |
| 2. Systematise | Give everything a fixed marked place so it is quick to find and put back |
| 3. Rails | Clean the workstation and use cleaning to detect wear and errors early |
| 4. Standardise | Write an application you can easily customize for each company |
| 5. Secure / maintain | Build habits and fixed checks so the standard holds — not just on the first day |
§Why it works
A neat and systematic workstation saves time — you do not have to look for tools or materials — and makes it easier to spot when something is wrong: a leak a loose screw or a missing tool jumps out on a clean and orderly station but drowns in mess.
- 01Less time spent looking for tools and materials
- 02Fewer errors, because deviations are easier to spot
- 03Better working environment and fewer trip hazards
- 04Easier training of new colleagues when everything has its fixed place
§5S in your daily life as a producer
You encounter 5S when you prepare your station at shift start, when you clean up after a task, and when you follow the markings on the floor and shelves that show where things belong. Many companies run regular 5S rounds where stations are reviewed and scored against a fixed checklist.
§5S as part of a larger lean culture
5S rarely stands alone. It is often the first step in a lean journey that can also include value stream analyses, standard work and continuous improvement boards where employees themselves suggest and implement small improvements. As a producer, you are part of driving this culture every time you point out waste or suggest a better way to do things.
“A clean orderly workplace is not an end in itself — it is a tool that makes errors and waste visible before they cost time and money.”
