Example of the Sigma Quality Level Calculator

Suppose you want to estimate the Sigma Quality Level for 50 defects in 1,000,000 opportunities at your plant. An opportunity is the unit for the defect count. It could be a single item or you might have multiple defects on a single item where each potential defect is an opportunity.

1. Select DOE > Design Diagnostics > Sample Size and Power.

2. Click the Sigma Quality Level.

3. Enter 50 for the Number of Defects.

4. Enter 1000000 as the Number of Opportunities.

5. Click Continue.
