5S is a method for organising a workplace so that everything needed is in its place, nothing unneeded is in the way, and problems are visible at a glance. The five steps are Sort, Set in order, Shine, Standardise and Sustain. It comes from Japanese manufacturing and is one of the first tools most companies use when they start with lean.
5S sounds like tidying up. It is not. Tidying is something you do before a visit. 5S is about building a workplace where it is obvious when something is missing, broken or in the wrong place, and keeping it that way without a big clean-up every month.
What does 5S stand for?
The five S’s come from five Japanese words. In English they are usually translated with words that also start with S.
| Step | Japanese | What it means | The question to ask |
|---|---|---|---|
| 1. Sort | Seiri | Remove everything that is not needed for the work | Do we use this? How often? |
| 2. Set in order | Seiton | Give everything a fixed, marked place, close to where it is used | Can anyone find it in 30 seconds and see when it is missing? |
| 3. Shine | Seiso | Clean the area and inspect while you clean | What is dirty, leaking, worn or broken? |
| 4. Standardise | Seiketsu | Write down and show the agreed way, so every shift does the same | What does good look like, and is it shown on the spot? |
| 5. Sustain | Shitsuke | Make it a habit, with short regular checks | Who checks, how often, and what happens with what they find? |
The first three steps change the workplace. The last two keep the change from fading, and they are the ones most often skipped.
How do you implement 5S, step by step?
Start with one area: a workstation, a line, a store room or a maintenance workshop. Involve the people who work there; 5S done to a team rarely lasts.
- Take photos before you start. They show the progress later and help settle arguments about what was there.
- Sort with red tags. Put a red tag on anything that may not be needed. Tagged items go to a holding area for a set time, for example two weeks. Anything nobody asks for is moved, sold or thrown away.
- Set in order. Place items by how often they are used: daily within reach, weekly nearby, rarely in storage. Use shadow boards, floor markings, labels and colour codes so every item has one obvious place.
- Shine. Clean everything, and treat cleaning as inspection. A clean machine shows leaks, cracks and loose parts that dirt was hiding. Agree who cleans what, and how often.
- Standardise. Turn the result into a simple standard: a photo of the area as it should look, a short checklist, a cleaning schedule. Put it where the work is done.
- Sustain. Run short, regular audits with the checklist below, show the score on the area’s board, and act on what the audit finds. Rotate who does the audit so everyone learns to see the standard.
Plan two to four weeks for the first area. After that, most teams spread 5S one area at a time rather than across the whole site at once.
What does 5S look like in practice?
Here is a typical example from a maintenance workshop, simplified.
Before 5S, the team spends a lot of time looking for tools, and three people have their own sets because the shared ones are never where they should be. Sort: the team tags 140 items in a week; 90 are never asked for and are removed, including broken tools and parts for machines the site no longer has. Set in order: the remaining tools go on shadow boards by job type, with the most used at the workbench. Shine: while cleaning, the team finds an oil leak on a compressor that had gone unnoticed under the dirt. Standardise: a photo of each board and a one-page cleaning schedule hang on the wall. Sustain: a five-minute audit every Friday, done by a different person each week.
The point of the example is the leak. 5S is not about looking good; it makes problems visible early, when they are cheap to fix.
What is the difference between 5S and 6S?
6S adds a sixth S, Safety. In each area, the team also looks for hazards: trip risks, blocked emergency exits, missing guards, badly stored chemicals. Some companies prefer 6S because it makes safety an explicit part of every audit.
Others argue that safety already belongs in every step: sorting removes clutter people trip over, setting in order keeps exits clear, and shining shows leaks. Both views work. What matters is that safety is checked, not whether it has its own letter.
A 5S audit checklist
A 5S audit is a short walk through the area with a checklist, scored the same way every time. Keep it short enough to finish in five to ten minutes. Score each line from 0 (not at all) to 4 (fully, every time).
| Step | Check |
|---|---|
| Sort | Only items needed for the work are in the area |
| There are no unused tools, materials or equipment | |
| Notice boards hold only current information | |
| Set in order | Every item has a marked, labelled place |
| Items are in their place, or it is obvious where they are | |
| Walkways, exits and safety equipment are clear and marked | |
| Shine | Floors, machines and workstations are clean |
| Cleaning materials are available and in their place | |
| Leaks, damage and wear are reported and tagged | |
| Standardise | A photo or standard shows how the area should look |
| The cleaning schedule is up to date and followed | |
| Everyone in the area knows the standard | |
| Sustain | Audits happen on schedule |
| Actions from the last audit have been closed | |
| The score is shown in the area and discussed |
Track the score over time rather than chasing a perfect number. A falling score is useful information: something has changed, and the team should find out what. For a similar checklist on the wider shop floor, see our gemba walk checklist.
What are the most common 5S mistakes?
- Treating it as a clean-up day. A one-off tidy without standards and audits is back to normal within weeks.
- Doing it to people, not with them. If outsiders decide where everything goes, the team that works there will move it back.
- Stopping after the first three steps. Standardise and Sustain are where 5S succeeds or fails.
- Labels everywhere, thinking nowhere. Marking every drawer is not the goal. The goal is that anyone can see at a glance whether the area is as it should be.
- Audits nobody acts on. If audit findings never lead to a fix, people stop taking audits seriously. Each finding needs an owner.
- Only in production. 5S works in offices, labs, warehouses and on shared drives too. The steps are the same.
How does 5S fit with kaizen and PDCA?
5S is often the first step in a kaizen programme, because it gives quick, visible results and teaches teams to see waste. Each 5S audit is also a small PDCA cycle: check the area against the standard, find the cause of any gap, fix it and adjust the standard if needed.
Audits and daily work turn up small problems and ideas all the time: a better place for a tool, a guard that is missing, a label that confuses the night shift. The value of 5S depends on whether those get fixed. In Hives, people can submit an improvement in about two minutes from a phone or a QR code on the wall, a manager can assign it, and everyone can see what happened to it. Our guide to employee-driven continuous improvement goes into how to keep those ideas coming.
Frequently asked questions
What are the 5S steps?
Sort (seiri), Set in order (seiton), Shine (seiso), Standardise (seiketsu) and Sustain (shitsuke). You remove what is not needed, give everything a fixed place, clean and inspect, write down the standard, and keep it with regular audits.
Where does 5S come from?
5S comes from Japanese manufacturing, where it grew up alongside the Toyota Production System. It became widely known outside Japan in the 1990s, helped by Hiroyuki Hirano’s book 5 Pillars of the Visual Workplace, published in English in 1995.
What is the difference between 5S and 6S?
6S adds Safety as a sixth step, so every area is also checked for hazards such as blocked exits or missing guards. Many companies get the same effect by including safety checks within the five steps.
Is 5S only for factories?
No. 5S works in any shared workspace: warehouses, workshops, labs, hospitals, offices and even shared folders on a computer. The steps are the same; only what you sort and store changes.
How often should you do a 5S audit?
Most teams do a short audit weekly in each area, and a deeper one monthly or quarterly with someone from outside the area. Short and regular beats long and rare.
How long does it take to implement 5S?
Plan two to four weeks for a first area, from sorting to the first audits. Spreading it across a whole site takes months, done one area at a time. Keeping it going never ends, which is why Sustain is the fifth step.
