5S is the most misbought product in lean. It looks like tidying, so companies either do it themselves as a cleanup week - and watch it decay within six months - or they buy it wrapped inside a large transformation program at ten times the necessary price. The right purchase sits in the middle: a scoped project with a senior facilitator, one pilot area, and a hard focus on the two S nobody wants to do.
What you are actually buying
The five steps - Sort, Set in order, Shine, Standardise, Sustain - are easy to list and unevenly hard to do. The first three produce the visible result: cleared areas, shadow boards, floor markings, material zones. Any competent facilitator gets you there in a week, and it is worth having: typical productivity gains in a properly organised area run 10 to 25%, mostly because searching disappears.
The last two are the actual product. Standardise turns the new state into photographed, auditable standards per workstation. Sustain builds the audit rhythm - shift lead daily in five minutes, area lead weekly, plant lead monthly - that decides whether the area still looks this way in month twelve. A facilitator who talks mostly about the workshop and vaguely about the audit rhythm is selling you the decay scenario.
The scoped format that works
- Week 0 - pick the pilot. One line, one cell, one workshop. Not the whole plant. The pilot's job is to become the argument for scaling.
- Weeks 1 to 2 - kickoff workshop (3 to 5 days). The team that works in the area does the sorting and organising; the facilitator structures, challenges, and photographs. Output: a visibly transformed area.
- Weeks 3 to 6 - standardise. Area leadership writes the 5S standards with photos and an audit checklist. The facilitator coaches; they must not write the standards themselves, or the standards belong to nobody.
- Weeks 7 to 12 - sustain and hand over. Audit rhythm runs with real findings and real fixes. The facilitator's presence tapers deliberately to zero. The last deliverable is a scaling recommendation.
Senior support through this arc is part-time - typically 15 to 25 practitioner days total. In Switzerland that prices a pilot at roughly CHF 30'000 to 60'000 as a scoped, outcome-priced project; see our rates guide.
Where 5S goes wrong
The failure modes are well known and almost always leadership failures, not method failures: selling it as a cleanup ("then it comes back in six months"), leadership exempting its own spaces, no audit rhythm after the workshop, and skipping the pilot to blitz the whole plant at once - which converts a culture-building tool into a compliance exercise.
In regulated environments - GMP production, labs, hospitals - 5S carries a bonus: visual order directly supports FDA, Swissmedic and notified-body audits. That makes the sustain phase easier to defend to management, and makes a facilitator with regulated-industry experience worth the premium.
FAQ
How long does a 5S implementation take?
A pilot area takes 8 to 12 weeks end to end: a 3 to 5 day kickoff, four weeks of standardisation, and an audit rhythm bedding in. Plant-wide rollout then proceeds area by area, each faster than the pilot.
What does a 5S project cost in Switzerland?
A senior-facilitated pilot runs roughly CHF 30'000 to 60'000 outcome-scoped, at 15 to 25 practitioner days. The larger investment is your own team's workshop time - plan for it explicitly.
Can we do 5S ourselves without a consultant?
The first three S, yes - teams do it well with good preparation. External senior facilitation earns its fee in the standardise/sustain phases and in keeping leadership honest about its own role. That is exactly where self-run efforts typically die.
Is 5S worth it in an already-clean Swiss plant?
Clean is not organised. The test is not dirt; it is whether anyone searches for tools, materials, or information. If searching exists, 5S has a return - Swiss plants are not exceptions, they are just better at hiding the waste.
