What is Six Sigma? It is a business process that enables companies to increase profits dramatically by streamlining operations, improving quality, and eliminating defects or mistakes in everything a company does, from filling out purchase orders to manufacturing airplane engines. While traditional quality programs have focused on detecting and correcting defects, Six Sigma encompasses something broader: It provides specific methods to recreate the process itself so that defects are never produced in the first place.
When GE reduced its costs from 20 percent to less than 10 percent, it saved a billion dollars in just two years - money that goes directly to the bottom line. This is the reason Wall Street and corporations as diverse as Sony, Ford, Nokia, Texas Instruments, Canon, Hitachi, Lockheed Martin, American Express, Toshiba, DuPont, and Polaroid have embarked on corporate-wide Six Sigma programs. Six Sigma should be of paramount importance to every forward-thinking executive and manager determined to make their company world-class in their industry.
