Data Source and Methodology
All calculations are based on the standard Six Sigma methodologies. For further reading, consult the Six Sigma Handbook.
The Formula Explained
The DPMO is calculated using the formula: DPMO = (Defects / (Units Produced × Opportunities per Unit)) × 1,000,000
Glossary of Terms
- Units Produced: Total items manufactured or processed.
- Defects: Number of defective items found.
- Opportunities per Unit: Potential defect opportunities in each unit.
How It Works: A Step-by-Step Example
Consider a production batch of 10,000 units with 200 defects and 5 opportunities per unit. The DPMO is calculated as follows: (200 / (10,000 × 5)) × 1,000,000 = 4,000.
