Six Sigma is a system for improving the quality of organizational processes. It was originally developed at Motorola in the 1980's and has become one of the most widely discussed and reported trends in business over the past two years, thanks largely to the phenomenal successes of the Six Sigma program at one of the world's most successful companies, GE. GE CEO Jack Welch, has been preaching about and implementing the Six Sigma philosophy throughout GE, and credits the program with millions of dollars in annual cost savings and product quality improvements.
