5S is the name of a workplace organization methodology that uses a list of five Japanese words which, transliterated and translated into English, start with the letter S. The list describes how items are stored and how the new order is maintained.

The 5S's are:

Phase 1 - Seiri (整理) Sorting: Go through all tools, materials, etc., in the plant and work area. Keep only essential items. Everything else is stored or discarded.
Phase 2 - Seiton (整頓) Straighten or Set in Order: There should be a place for everything and everything should be in its place. The place for each item should be clearly labeled or demarcated.
Phase 3 - Seisō (清掃) Sweeping or Shining or Cleanliness (Systematic Cleaning): A key point is that maintaining cleanliness should be part of the daily work - not an occasional activity initiated when things get too messy.
Phase 4 - Seiketsu (清潔) Standardizing:
Phase 5 - Shitsuke (躾) Sustaining the discipline: Maintain and review standards. Once the previous 4 S's have been established, they become the new way to operate. Maintain focus on this new way and do not allow a gradual decline back to the old ways. While thinking about the new way, also be thinking about yet better ways. When an issue arises such as a suggested improvement, a new way of working, a new tool or a new output requirement, review the first 4 S's and make changes as appropriate.
A sixth phase, "Safety," (安全) is sometimes added. It is reasonable to assume that a properly planned and executed 5S program will inherently improve workplace safety, but some argue that explicitly including this sixth S insures that workplace safety is given primary consideration.
