To collect data for a reliability metric like mean time to failure (MTTF), which tool would be most appropriate?

A requirements traceability matrix

A test management tool that records test execution results

When analyzing product quality metrics, what is the primary purpose of identifying trends?

To calculate the total cost of testing

To assign blame for quality issues to specific testers

To determine if the product quality is improving, deteriorating, or remaining stable over time

To replace the need for manual testing

A team observes that the defect detection percentage (DDP) has been decreasing over the last three releases. What is the most appropriate improvement action based on this metric?

Ignore the trend because DDP is not an important metric

Reduce the number of tests to save time

Increase the number of testers without changing the test process

Review and enhance the test design and execution strategies to improve defect detection

What is the primary purpose of product quality metrics in the context of testing process assessment?

To measure the efficiency of the testing team in executing test cases

To quantify attributes of the product, such as defect density and reliability, to support evaluation and improvement of testing

To calculate the cost of testing activities

To track the number of test cases executed per day
