What is Lean 5S?

Lean 5S is a workplace organization method that uses five principles—Sort, Set in Order, Shine, Standardize, and Sustain—to improve efficiency, safety, and productivity. Originally developed in Japan, 5S aims to eliminate waste, streamline processes, and create a clean, organized work environment. By consistently applying these steps, companies can reduce errors, save time, and foster a culture of continuous improvement. Many industries use Lean 5S as part of their broader Lean or Six Sigma initiatives.
