   A test manager is deciding whether to increase the depth of regression testing. The current defect detection percentage (DDP) is 85%, and the cost of testing is already high. Stakeholders are concerned about the budget. What is the most appropriate decision-making approach?

   • AReduce testing to save costs, since DDP is already high.
   • BAnalyze the cost-benefit of additional testing by comparing the cost of finding more defects vs. the cost of defects escaping to production.
   • CKeep testing as is because DDP is already high.
   • DIncrease testing because a higher DDP is always better.

   A test manager observes that the defect detection percentage (DDP) has decreased over the last three releases. What is the most appropriate interpretation?

   • AThe number of test cases is increasing
   • BThe testers are working faster
   • CThe testing process is becoming less effective at finding defects before release
   • DThe product quality is improving

   A test team is collecting data for defect detection percentage (DDP). They have two sources: the test management tool and the bug tracking system. The data from the two sources do not match. What is the most appropriate action?

   • ACalculate DDP using both sources and report the average.
   • BUse the test management tool data because it is more reliable.
   • CInvestigate the discrepancy and define a single source of truth for defect data.
   • DUse the bug tracking system data because it is the official record.
