Turning 5S Into a Sustainable Culture

When implemented correctly, 5S isn’t just about keeping a clean workspace—it’s a foundation for Lean thinking that: ✔️ Reduces wasted time searching for tools and materials ✔️ Prevents safety hazards and workplace injuries ✔️ Increases efficiency and productivity ✔️ Improves employee morale by making work easier and more organized

5S doesn’t fail because the concept is flawed—it fails because companies don’t sustain it.
