QuestionQ7

Analytic-based Improvement

You are a test manager responsible for a high-availability application. You have been assigned the goal of ensuring that the application is highly reliable and that its reliability-testing phase is efficient.

Which combination of the metrics below is MOST appropriate for measuring the efficiency of the reliability-testing phase?

Explanation

Measuring the efficiency of a reliability-testing phase requires combining metrics that track how test effort and time are being consumed against defect discovery progress, since efficiency is fundamentally a ratio of testing output (defects found, failure data gathered) to the resources and time invested, rather than a measure of the product's ultimate reliability outcome alone.
