The ppm in 6 sigma is 3.4 defects per million opportunities (DPMO).

• 6 sigma aims for a defect rate of 3.4 DPMO.

• PPM stands for parts per million.

• DPMO is a measure of process performance.

• The lower the DPMO, the better the process performance.

• Achieving 6 sigma means having a process that produces 99.99966% defect-free output.
