Solved-Assignment #4- Solution

Description

Consider the data listed in the following matrix for a product of size 120KLOC:

1. Calculate the defect removal rate for every phase

2. Calculate the defect injection rate for every phase

3. Calculate the defect escape rate for every phase

4. Calculate the overall defect removal effectiveness.

5. Which phase is the most effective in removing defects? Explain.

6. Do you think reviews and inspections were effective? Explain.

7. If the number of defects originated in design phase increased by 10% and defects detected in design review increased by 10%, do you think that will have a positive or negative impact on the defect removal effectiveness in the coding phase? Explain your answer in detail (present data to support your answer).
