Running a 5S Audit That Sticks
ngaide · 28 June 2026
5S is the foundation of a visual, disciplined workplace — and the most abandoned methodology in the plant. The reason is almost always the same: it gets run as a one-off cleanup instead of a system. The audit is what turns it into a system.
What 5S actually is
- Sort (Seiri) — remove what isn’t needed from the area; red-tag the doubtful.
- Set in order (Seiton) — a place for everything, everything in its place: labels, shadow boards, footprints.
- Shine (Seiso) — clean to inspect; cleaning is how you find leaks, wear and the first signs of failure.
- Standardize (Seiketsu) — make the first three a written, visual standard anyone can follow.
- Sustain (Shitsuke) — keep the standard alive through discipline, cadence and leadership.
An audit, not an event
A 5S blitz looks great on Friday and decays by the next week. A 5S audit is the feedback loop that stops the decay: a recurring, scored walk that holds the standard, surfaces drift early, and makes improvement visible to everyone.
How to score a 5S audit
Rate each criterion against a clear standard (a 0–4 scale works well), photograph the evidence, then roll the criteria up to a score per S and an overall percentage. Photos matter: they turn “it looks messy” into a specific, fixable finding.
Where 5S programs die: Sustain
The first four S’s are an afternoon of work. Sustain is forever, and it is where most programs quietly die. It can’t be bought with posters — it needs a fixed audit cadence, leaders who actually walk the floor, and standards that are visible at the point of use.
Make it stick
- Audit on a fixed cadence — a predictable rhythm beats intensity.
- Use photos as evidence, before and after.
- Give every finding a single owner and a due date.
- Make the score trend visible to the team.
