What step typically follows forming hypotheses in a structured troubleshooting process?

• A. Replacing suspected faulty components
• B. Documenting the plan
• C. Test the hypotheses
• D. Escalating to maintenance

Answer: (C)

Testing the hypotheses is the step where you gather evidence to confirm or refute each possible cause you proposed. After you form plausible explanations for the observed symptoms, you design focused checks, measurements, or experiments that would produce different results depending on which hypothesis is true. By comparing actual data to the expected outcomes, you move from guesswork toward a verified diagnosis. If a test supports a hypothesis, you’re closer to the real fault and can implement the fix with confidence. If the test disproves it, you refine your thinking and run additional tests for other possibilities. This approach avoids unnecessary component swaps and helps ensure the solution actually addresses the root issue. Planning or documenting actions is important, but those steps occur as you execute tests and determine the best corrective path, and escalation should come only if the issue can't be resolved within scope after testing.
