   What is the primary goal of using defect classification data to drive process improvement?

   • ATo document all defects for compliance purposes
   • BTo increase the number of defects found in each test cycle
   • CTo prevent defect recurrence by addressing the underlying causes
   • DTo assign blame to the team that introduced the most defects

   A team is investigating a recurring defect where customer discount codes are applied twice during checkout. The tester leading the analysis uses the 5 Whys technique. The first 'why' reveals that the discount is applied both in the cart service and the order service. The second 'why' reveals that the order service was updated to handle discounts independently. What should the tester do next to continue the 5 Whys analysis effectively?

   • AImmediately implement a fix to remove the duplicate discount application in the cart service.
   • BAsk why the order service was updated to handle discounts independently, continuing to trace the chain of causation.
   • CStop the analysis and classify the defect as a coding error in the order service.
   • DSwitch to a fishbone diagram to identify all possible causes in parallel.

   During test execution, a tester finds that a newly added field in the user profile form does not appear on the screen after saving, even though the database update succeeds. The developer confirms the data is stored correctly. The tester needs to classify this defect for the defect report. Which defect type best matches this observation?

   • AUser interface defect
   • BPerformance defect
   • CData integrity defect
   • DInterface integration defect

   A test manager is evaluating whether to adopt a defect classification scheme that includes categories for 'requirement', 'design', 'coding', 'integration', and 'testing' defects. The team wants to use the data to improve the development process. Which use of this classification data is most appropriate?

   • AUse the classification to decide which testers to promote based on the defects they find.
   • BUse the classification to assign blame to the team responsible for the phase with the most defects.
   • CReplace the need for root cause analysis by relying solely on the classification category.
   • DTrack the distribution of defects across phases to identify which phase introduces the most defects and target improvements there.
