Before Six Sigma became a cultural punch line — 30 Rock's Jack Donaghy is a green belt master — it was the gold standard in management philosophy. Developed in the 1970s and 1980s at Motorola and GE, Six Sigma-ites believe that the path to success is paved by near constant measurement of the performance of your company and workers. Instant feedback is the key. The Six Sigma Way, published in 2000 and co-written by Six Sigma guru Peter Pande, brought the management technique to the masses. The book draws heavily on the experiences of GE and other companies that successfully implemented the technique.
