Summary
Calculate Defects Per Million Opportunities (DPMO), sigma level, and first-pass yield for Six Sigma quality analysis.
How it works
- Enter total defects, total units, and opportunities per unit in Mode A.
- The calculator computes DPMO, DPU, DPO, sigma level, and first-pass yield instantly.
- Or switch to Mode B and enter a known DPMO to convert it directly to sigma level and yield.
- Use the sigma reference table to benchmark your result against industry standards.
Use cases
- Assess manufacturing process quality using DPMO and sigma level benchmarks.
- Convert a supplier-reported DPMO into a sigma level for vendor comparison.
- Track first-pass yield improvements over time in a continuous improvement program.
- Set defect reduction targets by working backward from a desired sigma level.
