Today Alex introduced the Troubleshooting Methodology that a Computer Technician should adhere to below:
- Identify the problem
- Establish a theory of probable cause
- Test the theory to determine cause
- Establish a plan of action to resolve the problem and implement the solution
- Verify full system functionality and if applicable implement preventative measures
- Document findings, actions, and outcomes
This serves as a guide or process to troubleshooting a computer system by gathering relevant information and excluding other possibilities to hone in on the mostly likely candidates for the failure. The next steps would be implementing the solution, verifying that it solved the problem (as well as checking that the solution did not create other issues) and documenting everything to reduce the recurrence of the same failure while serving as a reference for future concerns.
Alex practiced this methodology by simulating problems via question and answer to come up with the probable cause and solution in which everybody participated..
