A clean, orderly workplace is the foundation of efficient work, and it is the first thing a visitor judges you on. But 5S is not only about tidiness — it builds the habit of improvement and of working as a team.
The five Japanese words — seiri, seiton, seiso, seiketsu, shitsuke — are usually rendered as sort, set in order, shine, standardise and sustain.
Everyone wants a tidy workplace. Without a systematic programme, though, the results point in different directions, there is no standard, no continuity, and — most damaging — no assessment.
5S is not about cleaning
Cleanliness is a by-product of 5S, not its purpose. The purpose is to make abnormality visible. An area clean enough that a single drop of oil shows is an area that can tell you a leak started last night. An area that is always dirty can tell you nothing.
That is why 5S is the foundation of autonomous maintenance. The first AM step is initial cleaning as inspection: the operator finds the loose bolt, the weeping fitting and the wear pattern nobody had seen, because it is the first time they have put their hands over the whole machine.
Why 5S programmes fade
Everyone wants a tidy workplace; the problem is never the intention. Without a written standard, each department interprets tidy differently. Without an audit on a cycle, progress depends on which supervisor happens to care. Without recognition, the people who did it well stop within three months.
The sign that 5S is dying is all the activity clustering in the week before the audit. When you see that, the thing to fix is not the diligence of the staff but an audit cycle too far apart and a standard that plays no part in daily work.
| Expected outcome | How it is measured |
|---|---|
| The 5S activity itself | Run in a model area, then extended, with a written standard for orderliness |
| Audit and follow-up | An audit committee, scored inspections, and a summarised assessment |
| Motivation system | A promotion committee, area competitions, and an award scheme |
| Training | 5S for management, technique for running it, and technique for auditing it |
How to apply it on the floor
- Pick a model area and make the result unmistakable before extending it
- Photograph before and after in every area — memories are shorter than people think
- Write the standard for orderliness visually, not as long prose
- Appoint an audit committee that scores every area against the same criteria
- Tie 5S to step one of autonomous maintenance rather than running it separately
The mistakes we see most
- Treating 5S as a clean-up before management walks through
- Running it with no assessment, so nobody knows whether it improved
- Doing only the visible areas and never the machine room or the spares store
- Having no motivation system, so it stops when the enthusiasm does
Common questions
Does 5S have to come before TPM?
They can and should run together: step one of autonomous maintenance is cleaning-as-inspection, which is 5S with a purpose.
