Innovation | Lean Six Sigma, Six Sigma Certification

Six Sigma is a combination of the best elements of various quality improvement methodologies and a rigorous statistic-driven approach to performance improvement. The term “Six Sigma” was coined by Bill Smith, an engineer at Motorola. Six Sigma, in the present form, originated in the early 1980s at Motorola as a tool for reducing product-failure levels by 10 times in five years. General Electric (GE) implemented Six Sigma in 1995 after Motorola, and Allied Signal followed the Six Sigma trail after GE.

Six Sigma methodology evolved by combining the best elements of earlier quality improvement innovations.
