Six Sigma Goal: 3.4 DPMO (99.99966% Yield)

Overview

DPMO measures process quality by counting defects per million opportunities. Six Sigma = 3.4 DPMO (99.99966% defect-free). Essential for manufacturing, service quality, and process improvement initiatives.

💡

Pro Tips

Define 'opportunity' clearly—each chance for a defect.
Six Sigma = 3.4 DPMO; 5 Sigma = 233 DPMO.
Track DPMO over time to measure improvement.
Consider cost per defect for ROI calculations.

Fun Facts

"3 Sigma = 66,807 DPMO (93.3% good); 6 Sigma = 3.4 DPMO."
"Motorola developed Six Sigma methodology in 1986."
"Average company operates at 3-4 Sigma quality level."
"GE saved $12 billion using Six Sigma in first 5 years."

Formula: DPMO = (Defects / (Units × Opportunities)) × 1,000,000
