Six Sigma
Six Sigma is a method companies use to improve their business processes and reduce mistakes. Think of it as a problem-solving toolkit that helps make work more efficient and consistent. It uses data and statistics to find and fix issues in how things are done, whether that's manufacturing products, delivering services, or managing supplies. People who know Six Sigma are often valued because they can help save money by reducing waste and making processes work better. Similar approaches include Lean Manufacturing and Total Quality Management (TQM). When you see this on a resume, it usually means the person has been trained in process improvement and has earned certifications called "belts" (like Green Belt or Black Belt), similar to martial arts rankings.
