Which 5S term corresponds to standardizing processes?

• A. Seiri
• B. Seiketsu
• C. Seiso
• D. Seiton

Answer: (B)

In 5S, standardizing processes is Seiketsu, the fourth S. It focuses on creating and maintaining standards so the improvements from the first three steps don’t revert. That means establishing standard work, documented procedures, checklists, and visual controls, plus regular audits to ensure everyone follows the same methods. When Seiketsu is in place, sorting, arranging, and cleaning become repeatable practices across teams and shifts, not one-off efforts. The other terms map to the earlier steps: Seiri is about removing unneeded items, Seiton is organizing items for easy access, and Seiso is about cleaning and inspecting the workspace. (The fifth S, Shitsuke, is about sustaining those standards over time.)
