CAPM Practice: Demonstrate an understanding of common problem-solving tools and techniques

A Pareto chart identifies the vital few causes. The logical next step is to drill into the highest-priority categories using root cause analysis (e.g., fishbone diagram) to understand why they occur. The Pareto chart tells you WHERE to focus; root cause analysis tells you WHY and HOW to fix it.

**Why not A:** Presenting the Pareto chart and closing the quality issue is premature. The Pareto chart identifies which defect categories are most significant, but the underlying causes have not yet been investigated. Closing the issue without understanding why defects occur would not prevent recurrence.

**Why not B:** Resetting the check sheet and collecting new data would restart the data collection process without acting on the findings. The purpose of creating the Pareto chart was to guide further investigation, not to trigger another round of data collection.

**Why not C:** Creating a histogram to view the same data differently does not advance the analysis. The Pareto chart has already prioritized the defect categories. The next logical step is to investigate why the most frequent defects are occurring, not to reformat the existing data.
