What term is used to describe the techniques used to identify the source of a machine's malfunction?

The term that accurately describes the techniques used to identify the source of a machine's malfunction is troubleshooting. Troubleshooting involves a systematic approach to diagnosing problems within a system. It typically includes steps like gathering information about the malfunction, testing different components, and using logical reasoning to pinpoint the cause of the issue.

This process is fundamental in various fields, including electronics, machinery, and computer systems, as it allows technicians or engineers to efficiently resolve issues, thereby minimizing downtime and ensuring proper function. The focus during troubleshooting is primarily on isolating and identifying specific problems that prevent a machine from operating correctly.

While other terms may encompass related activities, such as fault diagnosis or fault hunting—which specifically refer to the act of searching for errors—they do not fully capture the broader and more systematic approach implied by troubleshooting. Machine maintenance, on the other hand, pertains to the routine upkeep and servicing of machines and is not specifically focused on identifying malfunctions.
