How to Use This Tool
Input Parameters
- Units Produced: Total number of units manufactured or processed
- Defects Found: Number of units that did not meet quality standards
- Defect Opportunities: Number of potential failure points per unit
- Sigma Shift: Adjustment for long-term process variation (typically 1.5σ)
Key Metrics
- First Time Yield (FTY): Percentage of units passing quality checks on first attempt
- DPMO: Defects Per Million Opportunities - standard measure of process performance
- Sigma Level: Measure of process capability - higher is better
