Which process involves the actions taken to diagnose and resolve issues within a system or network?

The process that involves actions taken to diagnose and resolve issues within a system or network is accurately represented by troubleshooting steps. Troubleshooting is a systematic approach that typically includes identifying the root cause of a problem, investigating potential solutions, implementing fixes, and testing to ensure that the issue has been resolved. This structured methodology is crucial in maintaining the availability and efficiency of IT systems.

While system analysis focuses more on assessing and evaluating systems to ensure they meet specified requirements, incident management is primarily about managing disruptive events and ensuring that service restoration occurs as quickly as possible. Change management deals with the processes related to making changes in a controlled and systematic way to minimize impact on services. Thus, troubleshooting directly addresses the hands-on diagnosis and resolution of specific issues, making it the appropriate choice in this context.
