What is Six Sigma?

 "Six Sigma" refers to a statistical measure of how far a process deviates from perfection. A process that operates at Six Sigma has a failure rate of only 0.00034%, producing virtually no defects. Six Sigma was developed by Motorola in the 1980s, and it has since been adopted by many other companies around the world, including General Electric, Toyota, and Amazon. It is used in manufacturing, healthcare, finance, and service industries to improve customer satisfaction, reduce costs, and increase profits.
