Troubleshooting Methodology for Tech+

IT professionals use a structured troubleshooting methodology. CompTIA defines a six-step process: 1. Identify the problem: Gather information. Ask about error messages, what was happening, recent changes. Determine scope. 2. Establish a theory of probable cause: Consider likely reasons and question the obvious. Research if necessary. 3. Test the theory to determine the cause: Check if your hypothesis is correct. If not confirmed, return to step 2. 4. Establish a plan of action and implement the solution: Devise and execute a fix with minimal impact. 5.
