Key takeaways
- 5S stands for Sort, Set in order, Shine, Standardise and Sustain.
- It is the foundation of lean and TPM: a clean, organised workplace makes problems visible.
- 5S is not about tidiness for its own sake; it removes waste and exposes abnormalities.
- Sustain is the hardest step and the one that decides whether 5S lasts.
5S is a simple, visual method for organising a workplace so that the right things are in the right place and problems are easy to see. It is usually the first step in a lean or TPM journey, because almost every other improvement is easier on a clean, organised floor.
The five S's
Each S builds on the last:
- Sort (Seiri): remove everything not needed for the work; red-tag doubtful items.
- Set in order (Seiton): a place for everything and everything in its place, with shadow boards and clear labels.
- Shine (Seiso): clean the area and the equipment, and treat cleaning as inspection.
- Standardise (Seiketsu): make the first three S's a defined, visual standard everyone follows.
- Sustain (Shitsuke): keep it going with habits, audits and leadership. Some sites add a sixth S for Safety.
Why 5S matters
5S is not housekeeping for appearance. A disorganised area hides problems: a leak under clutter, a missing tool that adds motion waste, a stock of defects no one noticed. By making the normal state visible, 5S makes the abnormal jump out, which is the foundation of both quality and reliability. It directly attacks the motion and waiting wastes.
How to run 5S
Start in one area. Run a Sort with red tags, decide locations and build shadow boards in Set, deep-clean in Shine, then write the visual standard. Take before and after photos. Keep it practical and owned by the team that works there, not imposed from outside.
Sustaining 5S
Most 5S efforts fade because Sustain is skipped. Sustain needs short, regular audits, a visible standard, and leaders who walk the floor and notice. When 5S is tied to daily work and autonomous maintenance, it sticks. When it is a one-off event, it slips back within weeks.

FAQ
What does 5S stand for?
Sort, Set in order, Shine, Standardise and Sustain. Some organisations add a sixth S for Safety, making it 6S.
What is the hardest part of 5S?
Sustain. It is easy to clean and organise once; keeping it that way needs habits, audits and leadership attention.
How does 5S relate to TPM?
5S is the foundation under the TPM pillars. Autonomous maintenance and focused improvement are far easier on a clean, organised, 5S floor.
