Techopedia explains Troubleshooting
Troubleshooting is primarily done to keep a system or software in desired condition, specifically when it encounters or exhibits a problem. It is a systematic approach done within one or more phases depending on the complexity of a problem. Typically, the first step involves identifying what the problem is followed by coming up with a solution to counteract the problem and then implementing that solution. However, there can be more than one reason for the problem, which will require a more complex solution. An individual troubleshooting such a problem might test for different solutions to eliminate the problem or fault.
