5S comes from Japanese workplace management and consists of Sort (Seiri), Set in Order (Seiton), Shine (Seiso), Standardize (Seiketsu) and Sustain (Shitsuke). Sort separates what is needed from what is not; Set in Order assigns locations, quantities and labels so items are easy to find and return; Shine removes dirt and checks equipment; Standardize turns the first three S into documented standards; Sustain builds the habit of following the rules. 5S is the foundation of lean and TPM and shapes the first impression auditors and customers form of a plant.
Use it for workplace organization, lean implementation, audit readiness before customer audits such as VDA6.3 or LPA, and new line or cell setup. The tool is also useful when a plant struggles with clutter, lost tools or low audit scores. Start with a pilot area, prove results, then roll out horizontally.
Form a 5S promotion team, train all staff, then run the five stages: red-tag campaign to clear unwanted items (Sort), three positioning plus visual management such as shadow boards and floor lines (Set in Order), zone responsibilities with inspection checklists (Shine), documented standards and checklists (Standardize), and morning meetings, training and assessment to lock in habits (Sustain). Score each area weekly with the 1-5 checklist and close out findings.
The scoring model uses the five elements with 4-6 observable checkpoints each, rated 1-5, with clear definitions of what passes to avoid subjective scoring. An example checkpoint for Set in Order is "shadow board present and all tools returned to labeled positions." Link results to team performance and review monthly trends to set the next improvement focus.
