The real skill in technical support is not fixing problems. It is identifying the correct problem.
A common pattern
Many support cases start with:
"The camera is broken."
After investigation, the camera is fine. The root cause is somewhere else entirely - lighting, a loose cable, a process change upstream, or an operator workflow that quietly changed last week.
The rule
Symptom does not equal cause.
This applies everywhere, not just in machine vision. The fastest fixers are the people who resist the obvious explanation long enough to confirm it.
