   A test team has been using GQM for a year. They have a goal to reduce production defects, but the metrics they selected (defect detection percentage and test coverage) have improved, yet production defects have not decreased. The team is considering adding more metrics. What should they do first?

   • AChange the goal to match the current metrics.
   • BStop using GQM because it is not working.
   • CAdd more metrics to get a fuller picture.
   • DRe-examine the questions to ensure they address the root causes of production defects.
