Six Sigma
Six Sigma is a method used by companies to improve their manufacturing processes and reduce mistakes. Think of it as a systematic way to solve problems and make products better. It was first developed by Motorola and later made famous by General Electric. Companies use Six Sigma to cut down on waste, save money, and make sure products are consistently high quality. When you see this on a resume, it often comes with levels like "Green Belt" or "Black Belt" - similar to martial arts rankings - showing how much training and experience the person has with these methods. Related approaches include Lean Manufacturing and Total Quality Management (TQM).
