What is the systematic approach for diagnosing a problem?

• A. Random trial without data.
• B. Define the problem, gather data, generate options, choose a solution, and verify results.
• C. Guess and apply.
• D. Immediately replace parts.

Answer: (B)

Diagnosing a problem well means following a structured, evidence-based process that guides actions from understanding to verification. Start by defining the problem clearly and what a successful resolution would look like. Then gather relevant data—symptoms, measurements, conditions, timelines—to better understand the issue. Next, generate a range of possible explanations or solutions and evaluate them against the data. Choose the most plausible option, implement it, and then verify results to confirm the problem is resolved and no new issues were created. This approach prevents guesswork, helps identify root causes, and provides a logical trail of steps you can repeat if needed. The other methods skip essential steps: random trial without data relies on chance, guessing and applying lacks evidence, and immediately replacing parts can be costly and may not address the actual cause.
