Keeping track of the common faults and their causes aids in ______.

• A. Troubleshooting
• B. Root cause analysis
• C. Forecasting
• D. Quality control

Answer: (B)

Documenting faults and their causes provides the data needed for root cause analysis. When you keep track of what goes wrong and why, you start seeing patterns that point to the underlying factors in the process. That enables you to identify the true origin of problems and implement fixes that prevent recurrence, rather than just addressing symptoms. While troubleshooting tackles a specific, immediate issue, forecasting looks ahead to potential future problems, and quality control focuses on meeting standards. Using fault data to uncover the fundamental cause is exactly what root cause analysis is for, making it the most appropriate choice.
