What is 5S? The five steps, with examples from work and home

What 5S means

5S is a systematic way to organise and maintain a workplace. It removes what is not needed, gives everything that is needed a fixed and visible place, keeps the area clean enough that abnormalities stand out, and turns those habits into a standard that people keep without being told.

The name comes from five Japanese words that each start with S. Each language has its own version, and Malaysian organisations often use the Malay terms from MAMPU’s public sector guide:

5S is often mistaken for housekeeping. Cleaning is only the third step. The point of 5S is that a tidy, standard workplace makes waste and problems visible: a missing tool, a leak, a pile of stock that should not be there, a document in the wrong tray. That is why lean organisations treat it as the base for everything else, from kanban to standard work.

The five steps, one at a time

5S and safety: is there a sixth S?

Many organisations, especially in construction, manufacturing and healthcare, call their programme 6S and add Safety as a sixth step: identifying hazards while sorting and setting in order, marking safe walkways and forklift routes, labelling hazardous materials and checking guards and protective equipment during Shine. Researchers have proposed ways to build occupational safety and health into 5S in this way (Jiménez and colleagues, 2019).

Others argue that a well-run 5S already includes safety, because each step removes hazards. Either way, safety should never be treated as an extra; if your sites track safety separately, 6S makes that explicit.

5S in Malaysia

5S is unusually well known in Malaysia because the public sector adopted it widely. MAMPU, the government’s administrative modernisation unit, published a 5S practice guide for public agencies in 2010, using the Malay terms Sisih, Susun, Sapu, Seragam and Sentiasa Amal. Public-sector 5S has since been rebranded as EKSA (Ekosistem Kondusif Sektor Awam, a conducive public sector ecosystem), with 5S still at its core.

The Malaysia Productivity Corporation (MPC) audits and certifies organisations under its Quality Environment Practices (5S) certification. Public bodies such as skills training centres and port authorities have reported receiving it, and many private manufacturers use the same framework.

If your organisation already runs EKSA or an MPC 5S programme, the steps in this guide are the same; the difference in a lean or Lean Six Sigma setting is the purpose. 5S is not the goal; it is the stable, visible base that makes flow, kanban and problem-solving possible.

Where 5S fits in Lean Six Sigma

In lean, 5S is usually one of the first tools a site puts in place, because visual management, standard work and pull systems all depend on a workplace where the normal state is obvious. In a Lean Six Sigma DMAIC project, 5S appears mainly in the Improve phase, as a quick fix for search time, motion and errors, and in the Control phase, where its standards and audits hold the gains.

5S also pairs naturally with the PDCA cycle: each 5S audit is a Check, and each fix to the standard is an Act. It is covered in our Lean Six Sigma Yellow Belt syllabus, and it is a full module of our Kaizen Yellow Belt course.

Visual tools for 5S

These four tools do most of the work in Set in order and Standardise. Each one shows at a glance whether the area is in its normal state.

Four common 5S visual tools

Floor marking tape. Marks walkways, storage spots and hazard zones. Agree one colour code for the whole site.	Labels and signs. Name every location and warn of every hazard, using standard symbols.
Shadow boards and tool foam. An outline for each tool, so a missing one is obvious.	Coloured tags. Red tags for items under review in Sort; status tags such as OK, On hold and Rejected for material.

How to run a 5S event in your area

1. Pick one pilot area that people can see, such as a store, a workstation or a shared office, and a team of the people who work there.
2. Take “before” photos from fixed points, and agree what “good” will look like.
3. Sort in one session. Red-tag doubtful items, move them to a holding area, and set a decision date (two weeks is common).
4. Set in order: decide homes by frequency of use, then mark, label and outline them.
5. Shine: clean deeply once, list every abnormality found, and fix or log each one.
6. Standardise: post the “after” photo, the checklist and the cleaning roster at the area.
7. Sustain: start a short daily check by the team and a monthly audit with a score, and review the scores at a team meeting.

The lowest score is the next improvement. Here, Sustain is weakest, so the team’s action is to put the daily check into the shift handover rather than to clean again.

Examples of 5S at work and at home

• Production line: only the parts and tools for today’s job at the station; tools on a shadow board; floor marked for material in, work in progress and finished goods.
• Warehouse: fast-moving items near dispatch; locations labelled; slow and obsolete stock red-tagged for a decision.
• Office and shared drive: one folder structure and naming rule for the team; old drafts archived; desks clear at the end of the day. This “digital 5S” often saves more time than the physical one.
• Hospital or clinic: supply rooms with labelled shelves and minimum levels, so staff spend less time searching for consumables.
• At home: sort the kitchen into keep, donate and throw away; give daily items a place near where they are used; clean as you go; agree a weekly reset with the family. The same five steps, smaller scale.

Published studies have looked at 5S in settings as different as hospitals, automotive plants and production companies, including its effect on patient waiting time and on working conditions and safety (see the sources below).

Common mistakes

1. Treating 5S as a cleaning day.A one-off clean-up without standards and audits is back to the old state within weeks.
2. Skipping Sort.Labelling and organising things nobody needs only makes the clutter neater. Remove first.
3. Doing it to people, not with them.If the team that works in the area does not decide where things go, the layout will not last.
4. Audits with no follow-up.A score nobody acts on teaches people that 5S does not matter. Close every audit action.
5. Stopping at 5S.A tidy area is the start. Use the visibility it creates to find and fix the causes of waste, with tools such as PDCA and kanban.

FAQ

Key takeaway

5S is not a clean-up; it is a standard that makes the normal state of a workplace obvious, so that anything abnormal stands out. Sort before you organise, inspect while you clean, write the standard down, and keep auditing until the habit holds.
