ITPEC IP April 2024 Question 53
ITPEC IP April 2024 — Question 53 of 100
The number of identified bugs is a metric directly related to program quality. Defect counts, defect density, severity distribution, escape rate, failure rate, and test coverage can provide evidence about correctness and reliability. A raw bug count must still be interpreted with program size, test effort, and severity, but it is the only option measuring a property of the software product.
Answer (d)
Why not others:
- (a) Budget at planning is a cost baseline or project-management measure
- (b) Return on investment measures expected or realized business value relative to cost
- (c) Delivery date concerns the project schedule
Key rule: Quality metrics describe defects or product characteristics; cost, benefit, and delivery metrics describe project or business performance.
