What is the standard sequence of steps in Troubleshooting Theory?

• A. Plan action, identify the problem, test the theory, implement action, verify functionality, document findings
• B. Identify the problem, document findings, implement action, verify, test theory
• C. Establish a theory of probable cause, identify the problem, test the theory, implement the plan, verify, and document findings
• D. Identify the problem, establish a theory of probable cause, test the theory, establish and implement a plan of action, verify functionality, and document findings

Answer: (D)

The sequence starts by identifying the problem because you can’t fix what you don’t understand. Gathering the symptoms, scope, and impact sets a solid foundation for a focused investigation. Next, you establish a theory of probable cause based on what you’ve observed. This keeps your investigation grounded in evidence rather than guesswork, guiding you toward the most likely sources of the issue. Then you test that theory to determine whether your suspected cause is correct. Testing helps confirm or refute hypotheses before you commit to a fix, which saves time and prevents unnecessary actions. Once the cause is verified, you develop and implement a plan of action to resolve the problem. This step translates your understanding into a concrete fix and deployment steps. After the fix is in place, you verify that the system is functioning as expected and that the issue is resolved without introducing new problems. Verification ensures lasting recovery and user satisfaction. Finally, you document what was found, what actions were taken, and the results. Documentation creates a record for future reference and helps others learn from the incident. Other sequences often rush to action or skip the verification and documentation steps, or they guess at the cause without testing, which can lead to incomplete or incorrect resolutions. This orderly flow—identify, form a probable cause, test the theory, plan and act, verify, and document—provides a reliable, repeatable approach to troubleshooting.
