   An agile team wants to improve their test automation reliability. They plan to introduce a new test data management approach. In the Plan phase, they define a hypothesis: 'Using a dedicated test data service will reduce flaky test failures by 30%.' What else must they define to make this hypothesis testable?

   • AThe specific metrics to measure, such as the number of flaky test failures per sprint, and the baseline value before the change.
   • BThe exact code changes needed to implement the test data service.
   • CThe names of the team members who will be responsible for the implementation.
   • DThe date when the improvement will be fully implemented.

   A team's PDCA cycle to improve test case review found that the new review process reduced defects by 10%, but the target was 15%. The team believes the process has potential but needs refinement. What should they do in the Act phase?

   • AAdjust the plan based on findings and run another PDCA cycle to refine the process.
   • BAnalyze the data more deeply to find the cause of the shortfall.
   • CDiscard the process because it did not meet the target.
   • DStandardize the process because it showed some improvement.

   A testing team has been using PDCA to improve their regression testing process. In the Plan phase, they set a goal to reduce regression test execution time by 30%. After several cycles, they achieved a 25% reduction. They are now in the Act phase. Which action best aligns with the PDCA philosophy?

   • AContinue running the same cycle until the 30% target is met.
   • BDiscard the process because it did not meet the 30% target.
   • CSet a new target of 25% and standardize the process.
   • DStandardize the current process because it achieved a significant improvement, and plan a new cycle to address the remaining gap.

   A large organization with multiple agile teams wants to improve their testing process using PDCA. They have identified that test environments are often unavailable, causing delays. In the Plan phase, they define a hypothesis: 'Implementing a self-service environment provisioning tool will reduce environment wait time by 50%.' What is the most important next step in the Plan phase?

   • ADefine the metrics to measure environment wait time and establish a baseline from current data.
   • BAsk all teams to manually track their environment wait time for a month.
   • CDecide to purchase a commercial tool without further analysis.
   • DImmediately start building the self-service tool to save time.
