Help desk troubleshooting steps should give you the same starting process for every ticket, even when you have never seen the fault before. Define the symptom, establish the expected result, find out what changed, test one change at a time, and verify the user's original task before closing the ticket.
The five steps that work on almost any problem
- Find out exactly what is wrong. Ask questions until you can describe the problem in one clear sentence.
- Find out what is supposed to happen instead. This gives you a clear goal to work toward.
- Ask what changed recently. Most problems start right after an update, a new setting, or a new piece of hardware.
- Change or check one thing at a time, then test again. If you change three things at once and it starts working, you will never know which one actually fixed it.
- Confirm the fix worked by having the person try the original task again, not just by checking that an error message went away.
That third step, changing one thing at a time, matters more than people expect. Say a computer is running slowly. If you close some programs, install an update, and restart the computer all at once, and it works, you still do not know which step actually helped. Next time the same problem shows up, you will be guessing again instead of knowing the real fix.
Finish every ticket by testing the real task, not just the error message. If someone could not open a certain program, do not stop once the program opens. Have them use it the way they normally would, so you know the problem is truly gone.
