What is the primary function of test metrics in evaluating system performance?

• A. To summarize the testing schedule
• B. To provide quantifiable data for assessment
• C. To assign tasks to team members
• D. To evaluate team performance

Answer: (B)

The primary function of test metrics in evaluating system performance is to provide quantifiable data for assessment. Test metrics are invaluable in the testing and evaluation process because they translate qualitative observations into quantitative measures that can be systematically analyzed. This allows teams to measure aspects such as reliability, performance, and quality of the system being tested. Quantifiable data enables stakeholders to have clear benchmarks and indicators to evaluate whether systems meet specific criteria and operational requirements. For example, metrics could include defect density, test coverage, or response times, enabling a comprehensive assessment of how well the system performs against established standards. This data-driven approach enhances decision-making, allowing for informed adjustments to improve system performance and effectiveness. Other options, while related to aspects of testing and evaluation, do not serve the primary role of providing a framework to measure and assess system performance objectively.
