Synonym discussion
Sense: noun/1
All three words describe finding and fixing issues, but they differ in scope and context. Diagnosis focuses specifically on identifying the cause — a doctor diagnoses an illness, and a mechanic diagnoses an engine fault — but does not necessarily include the repair step. Problem-solving is the broadest of the three, covering any kind of challenge from a math puzzle to a business strategy issue; it is not limited to malfunctions. Debugging is the narrowest and most technical, used almost exclusively for finding and removing errors in computer code or software. Troubleshooting sits between diagnosis and repair: it starts with identifying what is wrong and then decides on the fix. For example, a technician might diagnose a loose cable, then troubleshoot the connection by testing each port before repairing it.

Etymology
The word is a compound formed from 'trouble' (meaning difficulty or malfunction) and 'shooting' (from the sense of aiming and firing at a target). It originated in early 20th-century radio and telephone engineering, where technicians literally 'shot trouble' by tracing signal faults through a system. By the 1940s it had spread to general use for any systematic problem-solving activity.
