5S

整理整頓
WORKPLACE ORDER SYSTEM

Five Japanese principles, run in sequence, for organizing a workspace so problems are visible and standards hold without being policed.

整01 / 05

Seiri

Sort

Remove what the work doesn't need. If it hasn't earned its place at the station, it goes into storage, gets relocated, or is discarded.

頓02 / 05

Seiton

Set in Order

Give what's left a fixed home. Arrange tools and materials so anyone can find, use, and return them without asking.

清03 / 05

Seiso

Shine

Clean the space and inspect as you go. Dirt and disorder hide wear, leaks, and defects — cleaning surfaces them early.

潔04 / 05

Seiketsu

Standardize

Turn Sort, Set in Order, and Shine into a shared routine — written down, scheduled, and done the same way by everyone.

躾05 / 05

Shitsuke

Sustain

Make the standard a habit, not an event. Regular audits and shared ownership keep the system from decaying back to clutter.
