What it argues
A business-school technical note that explains Six Sigma’s history (Motorola in the 1980s, then General Electric), its statistical meaning, and its core methods, especially the define–measure–analyze–improve–control cycle and the roles that run Six Sigma projects. It defines Six Sigma as a rigorous, data-based way to improve critical processes by measuring their variation from customer requirements, and illustrates the method with a case study.
