Defect Detection Percentage (DDP) measures the effectiveness of testing efforts in identifying defects. Key aspects include:
Calculation formula:
Defect Detection Percentage is calculated using the formula:
DDP = (Number of Defects Found by Testing / Total Number of Defects Found by All Means) × 100
This metric expresses the efficiency of the testing process in identifying defects as a percentage.
Purpose:
- Evaluates the efficiency of test cases and methodologies used during testing phases.
Importance:
- Helps determine how well testing practices are identifying existing issues before release.
Benefits:
- Provides insights into test coverage effectiveness.
- Guides improvements in testing strategies based on detection rates.
Limitations:
- May vary significantly based on project context and complexity.
- Requires accurate tracking of all detected defects for meaningful analysis.
DDP is an important metric for assessing the effectiveness of quality assurance efforts
