1.2.1 Best Practice Methodology - Quick Notes
Problems have 3 parts: cause, symptom, consequence. Fix the consequence first (impact on user), then the cause.
CompTIA's 6-Step Troubleshooting Model
- Identify the problem - gather info from the user, note any recent changes, back up if needed, and start documentation.
- Establish a theory of probable cause - question the obvious and research if needed.
- Test the theory - if confirmed, plan next steps; if not confirmed, form a new theory or escalate.
- Plan and implement the solution - follow vendor instructions.
- Verify full functionality - add preventive measures if applicable.
- Document everything - findings, actions, outcomes, and lessons learned.
