# 🔎 Troubleshooting Methodology

My lab projects use a structured support process:

1. Identify the reported symptom
2. Determine the affected user, device, application, or cloud resource
3. Reproduce the problem when appropriate
4. Gather error messages and evidence
5. Identify the affected technical layer
6. Review configuration, permissions, logs, and dependencies
7. Isolate the root cause
8. Apply the smallest appropriate corrective action
9. Retest the required functionality
10. Verify security and access boundaries
11. Document the resolution

This approach helps separate problems involving:

- Identity
- Authentication
- Authorization
- Networking
- Endpoints
- Applications
- Cloud resources
- Microsoft 365 services
- Automation
- Monitoring
- Platform health
