Defect Escape Rate
What Is Defect Escape Rate?
Defect Escape Rate measures how many defects are found after release instead of being caught earlier during development, review, or testing.
Why Defect Escape Rate Matters
It helps teams understand:
- release quality,
- test effectiveness,
- how much risk escapes into production,
- where prevention controls are weak.
