Lean Six Sigma
Lean Six Sigma is a method for making businesses work better by reducing waste and mistakes. It combines two approaches: 'Lean' (which focuses on eliminating unnecessary steps) and 'Six Sigma' (which aims to reduce errors). People who are trained in this get different colored "belts" (like in martial arts) - Yellow, Green, and Black Belts - showing their level of expertise. Companies use Lean Six Sigma to save money, make customers happier, and get work done faster. You might also see it called "LSS," "Continuous Improvement," or "Process Excellence."
