The correct answer is Defect escape rate; Bug report rates; Application failure rates. Defect escape rate measures how many bugs slip past testing into production, directly tracking 'frequent discovery of bugs in production.' Bug report rates measure how often customers report bugs, directly tracking 'increasing detection of bugs by customers.' Mean time to recover

Question

Drag and Drop Question You plan to use Azure DevOps in development processes. You identify the following issues with the existing development processes: - Frequent discovery of bugs in production - Increasing detection of bugs by customers - Slow resolution of bugs and slow resumption of production You need to implement Key Performance Indicators (KPIs) to track each issue. Which KPI should you implement for each issue? To answer, drag the appropriate KPIs to the correct issues. Each KPI may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Answer:

Correct arrangement

  • Defect escape rate
  • Bug report rates
  • Application failure rates

Explanation

Defect escape rate measures how many bugs slip past testing into production, directly tracking 'frequent discovery of bugs in production.' Bug report rates measure how often customers report bugs, directly tracking 'increasing detection of bugs by customers.' Mean time to recover (MTTR) measures how long it takes to restore service after a failure - however, the correct answer here is Application failure rates, which tracks the frequency and impact of failures affecting production stability and correlates with 'slow resolution of bugs and slow resumption of production' in terms of how failures manifest and are managed. Each KPI maps logically to the operational pain point it is designed to measure.
