What Is Six Sigma?
Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company's operational performance by identifying and eliminating "defects" in manufacturing and service-related processes. Commonly defined as 3.4 defects per million opportunities, Six Sigma can be defined and understood at three distinct levels: metric, methodology and philosophy
The goal of Six Sigma is to increase profits by eliminating variability, defects and waste that undermine customer loyalty.
