The Third Pillar: Cleanliness
Here's what I do when I inspect a factory for 5 S conditions — I visit the mens restroom. The restroom is always a good indicator of 5S conditions. I look around. Are there any unneeded items? Are the toilet paper, soap, and other needed items all kept in clearly designated places? Are the windows dirty or the windowsills dusty? No one likes cleaning restrooms, and for this very reason they provide at-a-glance evidence of how well 5 S conditions are being maintained throughout the factory.
