What is the fourth step of the CompTIA troubleshooting methodology?
Establish a theory of probable cause
Establish a plan of action to resolve the problem and implement the solution
Verify full system functionality and, if applicable, implement preventive measures
Identify the problem
CompTIA's six-step troubleshooting methodology helps technicians work systematically. After identifying the problem, establishing and testing a theory, the fourth step is to create a detailed plan to fix the issue and then carry it out. Planning ensures that risks and business impacts are considered before making changes. The remaining steps are to verify full system functionality (and add preventive measures) and to document findings, actions, and outcomes.
