What is 5S?
5S takes its name from five Japanese terms: Seiri, Seiton, Seiso, Seiketsu and Shitsuke. Common English equivalents are Sort, Set in Order, Shine, Standardize and Sustain. EPA describes a recurring approach to workplace order and visual management. NIST MEP highlights arranging necessary tools so their correct location is apparent. The Lean Enterprise Institute emphasizes team ownership and continuing improvement. The examples below are practical editorial suggestions for facility and cleaning teams, rather than reported company results.
Seiri — Sort: decide what is needed
Separate necessary items from items that require a decision. In a cleaning supply room, a useful starting question is: which tools belong to the current service scope? Suggested application: make a review list of damaged tools, duplicate accessories and items whose owner is unknown. Ask the authorized facility representative to decide what may be removed, reassigned or replaced. Do not discard client property or unidentified materials merely because they appear unused.
Seiton — Set in order: give necessary items a place
Arrange needed items so they can be located and returned consistently. Suggested application: agree on a cart layout and label storage positions with plain words or symbols. Make a simple location map for backup staff. Use readable labels alongside any color system so identification does not depend on color alone. Before reorganizing a client’s storage area, confirm who controls the space and which arrangements must remain in place.
Seiso — Shine: clean and observe
Clean the work area and look for abnormal conditions. Suggested application: while completing an authorized restroom task, record a recurring damp patch with the room, time and location, then notify the designated contact. A cleaning observation is a handoff for assessment, not a diagnosis or permission to repair equipment. Give staff a clear way to report conditions that prevent completion of the checklist.
Seiketsu — Standardize: make the routine clear
Establish shared instructions that maintain sorting, order and cleanliness. Suggested application: keep a short cart setup sheet, a task-and-frequency checklist and a shift handoff form together. State who replenishes supplies, who reviews a reported shortage and which version of the checklist is current. Any reference photo should show an approved arrangement without revealing access codes, confidential information or identifiable occupants.
Shitsuke — Sustain: build a habit the team can maintain
Maintain the agreed practices through regular participation and review. Suggested application: include a brief storage and cart check at shift handoff, then discuss recurring difficulties in a scheduled team conversation. Ask what makes returning equipment or completing the checklist difficult. A missing storage position, unclear instruction or supply delay needs a practical response. Agree on changes with the people who perform the work and update their instructions.
A small pilot for a cleaning supply room
Choose one area with the client’s permission and name a client contact and a cleaning-team contact. Record the current layout and one specific problem, such as time spent locating replacement tools. Review which items are needed, agree on storage positions, clean the authorized surfaces and prepare a short reset checklist. Try the arrangement during actual shifts before extending it elsewhere. Set a review date so staff can explain what worked and what needs adjustment.
How to review progress without chasing a cosmetic score
Select a few measures relevant to the pilot: time spent locating a named tool, missing-item reports, supply shortages or incomplete handoffs. Record a starting point and compare similar operating periods. Treat scores and photos as prompts for discussion, with clear definitions and context. This article makes no numerical savings claim; the facility would need its own observations to judge whether the change helped.
Agree on the boundary between cleaning and workplace management
A facility-wide 5S effort needs decisions from the people responsible for the workplace. The cleaning provider can discuss storage observations and agreed cleaning routines, while the client retains authority over its assets, production areas and operational instructions. Put additional sorting projects, stock counts, labeling work and periodic reviews into the agreed scope before assigning them. 5S is an organizational method; any hazardous activity still requires the applicable site procedures and qualified personnel.
