An agile team is considering two metrics to evaluate their testing process: the number of test cases executed per day and the defect detection percentage (DDP). They want to choose the metric that provides the most useful insight for improving their testing process. Which metric should they choose and why?

Both metrics are equally useful, so the team should track both

DDP, because it measures the effectiveness of testing in finding defects before release

Number of test cases executed per day, because it measures the efficiency of the testing team

Neither metric is useful; the team should focus on qualitative feedback from testers

What is the best way to ensure improvement actions are integrated into the agile workflow?

Assigning them to a separate team outside the agile process

Adding them to the product backlog and prioritizing them

Implementing them immediately without planning

Discussing them in the retrospective but not documenting them

An agile team has noticed that the number of escaped defects has increased over the last three sprints. They want to identify the root cause. Which approach would be most effective in identifying improvement opportunities in their testing process?

Assign the most experienced tester to review all test cases before execution

Analyze the defect data to identify patterns, such as which areas of the application have the most defects and when they are introduced

Ask the development team to write more unit tests

Increase the number of test cases executed in each sprint

During a sprint retrospective, the team identifies that testers are not involved early enough in the user story development, leading to unclear acceptance criteria. What is the most effective improvement action to address this?

Create a checklist for testers to review stories after development is complete

Ask the product owner to write more detailed acceptance criteria

Delay testing until the story is fully developed

Have testers participate in story refinement sessions to help define acceptance criteria

Which step is typically first in applying the Agile Test Improvement Model?

Assessing the current testing practices

Defining the target testing process

Implementing a large-scale change to the testing process

Part of the Test Management and Test Process Improvement domain, which makes up ~24% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–14 in this domain), expect 2–4 from this objective — we provide 31 practice questions to prepare you well beyond it.
