Six Sigma

Six Sigma is a structured problem-solving, process improvement and quality management methodology composed of scores of integrated tools and techniques. Trained and validated practitioners use focused projects to statistically identify and isolate process variation within control limits in order to determine and implement appropriate countermeasures to promote stable processes. The overall intent is to reduce variability, error tendency and defects to achieve a six-sigma levels of performance — that is fewer than 3.4 defects per million — thereby lifting and sustaining product and service performance.
