According to the troubleshooting methodology, after determining the most likely probable cause of an issue, the technician should establish a plan of action to resolve the issue and identify potential effects. This means that the technician should develop a step-by-step plan for resolving the issue, taking into consideration the potential impact of each action.
The plan of action should include specific steps that address the probable cause of the issue. For example, if the issue is related to network connectivity, the plan of action might involve checking the cables, testing the network adapter, or resetting the network settings.
Additionally, the plan of action should consider any potential effects that the solution might have on other systems or components. For example, if the solution involves resetting the network settings, the technician should consider how this might affect other devices that rely on the same network.
Once the plan of action has been developed, the technician should then implement the solution or escalate as necessary. If the technician is confident in the proposed solution, they can move forward with implementing it. However, if the solution is more complex or could have a significant impact on the system, the technician might need to escalate the issue to a higher-level technician or manager.
After implementing the solution, the technician should then verify full system functionality and, if applicable, implement preventive measures. This involves testing the system to ensure that the issue has been resolved and that the system is functioning as expected. The technician should also consider implementing preventive measures to prevent similar issues from occurring in the future.
Finally, the technician should test the theory to determine the cause. While this step is listed as the last step in the troubleshooting methodology, it is important to note that the technician may have already tested various theories and determined the most likely probable cause before developing the plan of action. Testing the theory again at this stage is important to confirm that the issue has been fully resolved and that the underlying cause has been identified and addressed.
