Lean Six Sigma
Lean Six Sigma is a method for making work processes better and more efficient, combining two popular business improvement approaches: "Lean" (which focuses on eliminating waste) and "Six Sigma" (which focuses on reducing mistakes). Think of it like a recipe for making organizations run smoother. People who know Lean Six Sigma often have special certifications marked by "belts" (like in martial arts) - White, Yellow, Green, and Black Belts, with each level showing more expertise. Government agencies and large companies use this approach to save money, work faster, and serve people better.
