Six Sigma

Six Sigma is a quality management initiative that takes a very data-driven, methodological approach to eliminating defects with the aim to reach six standard deviations from the desired target of quality. Six standard deviations means 3.4 defects per million. A defect is defined as any unit that does not meet the specified level of satisfaction for the customer. Like TQM and other quality initiatives, Six Sigma includes tools used to drive down defects, improve quality and profits, and thus, morale and profitability.
