What does troubleshooting involve?

Troubleshooting involves a systematic approach to diagnosing and resolving problems that arise within a system, whether it be software, hardware, or a combination of both. This approach typically includes identifying the issue, analyzing potential causes, testing solutions, and implementing fixes to restore functionality. The key component of troubleshooting is its organized nature, which ensures that problems are addressed logically and effectively, minimizing errors and oversights in the process.

The other options, while related to technical work, do not accurately capture the essence of troubleshooting. Upgrading hardware, developing new software, and running automated tests could be parts of a broader technical workflow, but they are not specifically about systematically solving existing problems. Troubleshooting is distinct in that it is directly focused on problem resolution.
