Explain the troubleshooting methodology.

 

1. Identify the problem

·         Gather information

·         Duplicate the problem, if possible

·         Question users

·         Identify symptoms

·         Determine if anything has changed,

·         Approach multiple problems individually

 

Research knowledge base/Internet, if applicable

 

Establish a theory of probable cause

·         Question the obvious

·         Consider multiple approaches

·         Divide and conquer

 Test the theory to determine the cause

·         Once the theory is confirmed [confirmed root cause]

·         Determine the next steps to resolve the problem

·         If the theory is not confirmed, establish a new theory or escalate

 Establish a plan of action to resolve the problem and identify potential effects

 Implement the solution or escalate as necessary

 Verify full system functionality and, if applicable, implement preventive measures

 Document findings/lessons learned, actions and outcomes
