Shotgunning is the true mark of a very poor tech. They don't
want to learn why things fail, or what parts are actually needed.

Might I respectfully semi-disagree?

I have always wanted to understand why something wasn't working correctly
before I fixed it. But as products have become more complex and harder to
troubleshoot, it seems increasingly necessary to, on some occasions, shotgun.
I don't like it, but if you're running a repair business, you have to get the
item out the door to stay in business.

If it's of any interest, I have never had a callback on anything I've
repaired. But that was in the days when virtually all electronics was composed
of discrete components you could unsolder and test, if need be.
