Six Sigma
Six Sigma is a method that helps companies make their manufacturing processes better and reduce mistakes. It's like a toolbox of techniques that engineers and managers use to solve problems and make products more consistently. The name comes from a statistical term, but recruiters should know it's basically about making things right the first time and reducing waste. Companies like Motorola and General Electric made it famous, and now it's used across many industries. People who know Six Sigma often have special certifications called "belts" (like Green Belt or Black Belt), similar to martial arts rankings.
