   A team wants to analyze defects found in code inspections. They have access to inspection logs that include defect descriptions, but the logs do not categorize defects by type or phase. What should they do to improve data collection?

   • AAsk a single inspector to categorize all defects after the inspection.
   • BAdd fields to the inspection log for defect type and phase introduced.
   • CContinue with the current logs and rely on inspectors' memory.
   • DOnly record the most severe defects to reduce effort.
