Which process is used to diagnose and correct faults in a system?

Troubleshooting is the systematic process used to diagnose and correct faults in a system. This process involves identifying the symptoms of a problem, analyzing the potential causes, and determining solutions to restore the system to its proper functioning state. Troubleshooting typically follows a structured approach, which can include steps such as gathering information, reproducing the fault, and testing various components or systems to pinpoint the issue.

In contrast, quality assurance focuses on ensuring that processes and products meet specific standards and requirements, rather than addressing existing faults. Logistics support involves managing the resources needed to maintain and operate systems but does not directly pertain to diagnosing faults. Preventive maintenance aims to perform routine checks and maintenance to prevent issues before they arise, rather than correcting existing faults. Thus, in the context of diagnosing and correcting faults, troubleshooting is the most appropriate term.
