Six Sigma

Six Sigma is a disciplined, data-driven methodology for eliminating defects and reducing variability in manufacturing and business processes. The goal is to achieve a defect rate of no more than 3.4 defects per million opportunities (DPMO), corresponding to a 99.99966% yield.

Six Sigma uses structured problem-solving frameworks. DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs. Manufacturers certified in Six Sigma demonstrate a commitment to process excellence. On Speya (formerly Find My Factory), Six Sigma capability is an indicator of a manufacturer’s quality maturity.
