Explain the troubleshooting theory.

Explanation should include always considering corporate policies, procedures, and effects before implementing changes. Explanation should also include the steps of the CompTIA troubleshooting theory:

  1. Identify the problem. (Question the user and identify user changes to the computer and perform backups before making changes.)
  2. Establish a theory of probable cause (question the obvious). If necessary, conduct external or internal research based on symptoms.
  3. Test the theory to determine the cause.
    a. Once a theory is confirmed, determine the next steps to resolve the problem.
    b. If a theory is not confirmed, re-establish a new theory or escalate the problem.

  4. Establish a plan of action to resolve the problem and implement the solution.
  5. Verify full system functionality and, if applicable, implement preventive measures.
  6. Document findings, actions, and outcomes.
