   A test process improvement team is analyzing a high rate of escaped defects. They have built a cause-effect diagram and identified several potential causes, including 'testers not trained in requirements-based testing,' 'test environment not representative of production,' 'test data not realistic,' and 'test completion criteria not defined.' The team has limited resources and must choose which causes to address first. Which approach best balances the need for thorough analysis with the constraint of limited resources?

   • ASelect the category with the most causes and assume the root cause is within that category.
   • BPrioritize the causes using a combination of team voting and available defect data, then investigate the top-ranked causes in a focused manner.
   • CFocus only on the causes that are easiest to fix, regardless of their likely impact.
   • DInvestigate all causes simultaneously to ensure no potential root cause is missed.
