Troubleshooting Methodology
The 6-Step Troubleshooting Process
1. Identify the Problem
Gather detailed information about the issue, including when it started, what the customer was doing, and any error messages.
2. Establish a Theory
Based on the symptoms, develop a hypothesis about what might be causing the problem.
3. Test the Theory
Try the most likely solution first, starting with the simplest and least invasive options.
4. Evaluate Results
Determine if the solution worked. If not, establish a new theory and test again.
5. Document the Solution
Record what worked and what didn't for future reference and knowledge sharing.
6. Prevent Recurrence
Provide guidance to prevent the same issue from happening again.
