Historically speaking, Six Sigma has evolved from a quality improvement tool in the mid-1980s to a fact-driven system of business management in the 2000s. Over the last 20 years, there have been many events and contributions that have shaped Six Sigma. Even today, the evolution of Six Sigma continues – growing in both power and diversity, throughout the world.
