The 5S method: what it is and how to implement it step by step

Published 27 October 2026.

Many companies have run a “5S campaign”: a Saturday clean-up of the shop floor, yellow tape on the floor, labels on the racks. A month later the workstations are again full of things nobody needs and the tape is wearing off. The team remembers 5S as tidying up for show before a customer visit.

Yet 5S is not a campaign but a way of working. Done well, it cuts the time spent searching for tools and materials, reduces mistakes and makes problems visible before they stop production. Below we explain what each S means, how to implement 5S step by step and how to check that order is being kept.

What the 5S method is

5S comes from Japanese manufacturing practice and is most often associated with the Toyota Production System. It became widely known outside Japan through Hiroyuki Hirano's book “5 Pillars of the Visual Workplace” (English edition 1995). The name comes from five Japanese words, each starting with S. Interestingly, Toyota itself traditionally speaks of 4S and leaves out sustain, because its regular audits keep the standard in place anyway.

The order matters. There is no point labelling places for items that will be removed next week, or writing a standard for a workstation that is still being sorted. The last two steps are skipped most often, and they decide whether order lasts.

What 5S gives you

• Less searching. Tools, gauges and materials are where they should be, so work does not stop.
• Fewer mistakes. Labelled places and consistent labels make it harder to pick the wrong part or mix up versions.
• More safety. Clear walkways, nothing on the floor and leaks spotted earlier mean fewer trips and injuries.
• Problems are visible at once. An empty spot on the tool board or an oil stain under a machine is a signal that gets lost in a mess.
• Faster onboarding. A standard with a photo shows what the workstation should look like without long explanations.
• A basis for further improvement. Shorter changeovers, machine checks by operators and standardised work all need an organised workplace.

How to implement 5S in a company: a step-by-step guide

1. Set the goal and get management support. Write down in one sentence why the company is implementing 5S, for example to shorten changeovers on line 2 or to reduce picking errors. The area manager needs time for the implementation and later for the audits.
2. Choose a pilot area. One cell, line or part of the warehouse where the problem is visible and the team is willing to change. A small, well-run pilot convinces the rest of the plant better than a presentation.
3. Take photos and a baseline. “Before” photos from fixed points, a first score using the checklist below and one number linked to the goal, for example changeover time.
4. Train the area team. Briefly and with examples from your own floor. The people who work at the workstation decide what is needed and where it goes. 5S introduced by outsiders without the team will not last.
5. Sort with red tags. Every item in doubt gets a tag and goes to a separate holding area for a set period. Then a decision is made: it stays, it moves elsewhere or it is removed. For tools and equipment with a book value, disposal is decided by an authorised person.
6. Set in order. The most frequently used items closest to the point of use, the rest further away. Shadow boards for tools, floor markings for trolleys and containers, labels on racks. Check the layout over one full work cycle.
7. Shine with inspection. Agree a list of points to check while cleaning, who cleans, how often and how long it takes. That time has to be in the schedule, not “after the shift if there is time”.
8. Standardize. A photo of the target state at the workstation and a sheet with the labelling rules and cleaning schedule. Consistent colours and descriptions across the plant make later roll-out easier.
9. 5S audits. A short audit using the checklist, weekly at first and less often later. The result is discussed with the team at the workstation, and actions get a deadline and an owner.
10. Roll out. When the pilot area keeps the standard over several audits in a row, move to the next one. The pilot team is the best advocate for the next teams.

5S audit checklist

Each question can be scored on a simple scale, for example from 0 to 2. The trend matters more than the score itself, as does whether the actions from the previous audit were completed.

The most common mistakes when implementing 5S

• A one-off clean-up campaign instead of five steps and a standard.
• Rolling out across the whole plant at once, without a pilot and without the people who work at the workstations.
• No time for cleaning in the work schedule.
• Audits run by one person only, with the team never seeing the results.
• A contest for the best-looking workstation instead of the best-working one.
• A manager who never goes to the floor. The team quickly sees that nobody cares about the standard.

5S in the office

The same steps work at desks and in data. Sorting means removing unused files, folders and document versions. Setting in order means one agreed folder structure and file naming. The standard sets where contracts, orders and instructions are saved so that anyone can find them in seconds. Much of the time lost in an office goes on searching for information, not for objects.

How we can help

We implement 5S together with the team in a pilot area: from the baseline, through workshops at the workstations, to the standard and the first audits. 5S audits can be run in the vibe4you OS app, where questions, ratings, evidence and actions sit in one place. More on the Operations optimisation page. If you want to check first how organised your processes are, take the free operational maturity test. It takes 2 minutes and you get the result straight away.

Frequently asked questions

What does 5S stand for?

5S stands for five Japanese words starting with S: seiri (sort), seiton (set in order), seiso (shine), seiketsu (standardize) and shitsuke (sustain). Together they describe a way to keep the workplace organised, safe and easy to read.

How long does it take to implement 5S?

The first pilot area can be organised in a few weeks. Keeping the standard is ongoing work based on regular audits and a response to deviations. Further areas go faster because the team builds on the pilot.

What is the difference between 5S and 6S?

6S is 5S with a sixth step for safety, and some lean practitioners work that way. Whatever the number of steps, safety is best considered at every stage of organising the workplace rather than only at the end.

Does ISO 9001 require 5S?

No. ISO 9001 requires a suitable environment for the operation of processes (clause 7.1.4) but does not prescribe specific tools. 5S is one practical way to meet that requirement and show it to an auditor.
