The ratio of error found before s/w delivery and to the total errors (before and after) is called:
1.Accuracy
2.Specificity
3.Defect Removal efficiency✓ Correct
4.Through put
Solution
The correct answer is Defect Removal efficiency.
Key Points
Defect Removal Efficiency (DRE) is a measure used in software engineering to quantify the effectiveness of defect detection processes.
It is calculated as the ratio of defects found before delivery to the total defects (both before and after delivery).
The formula for DRE is: DRE = (Defects found before delivery) / (Total defects found before and after delivery).
Additional Information
Accuracy generally refers to the degree of closeness of measurements of a quantity to its actual (true) value, which is not directly related to defect detection in software.
Specificity is a term often used in statistical classification to refer to the ability of a test to correctly identify true negatives, which is not typically used in the context of software defect measurement.
Throughput refers to the rate at which a system can process tasks. It is more related to performance metrics rather than defect measurement.
