Frequently Asked Questions

Six Sigma is a quality management strategy and process improvement methodology that focuses on reducing variability and eliminating errors in manufacturing processes and business operations. The goal of Six Sigma is to achieve the maximum possible degree of quality and minimize defects to a level that corresponds to six standard deviations from the mean (hence the name "Six Sigma").

Six Sigma was developed by Motorola in the 1980s and later expanded by General Electric (GE). The Six Sigma methodology uses statistical tools and techniques, such as the DMAIC (Define, Measure, Analyze, Improve, Control) cycle, which provides a structured approach to process improvement.
