We have been known to fix the issue and then pretend we don’t know how it happened.

As a process engineer, sometimes that is the only way.

Heck, I’ve even fixed the issue without knowing how I did it, or the reason it worked.

Worse, I know of two ways brightness of LEDs was improved early on, my way which causes a 70% improvement, and the way a later colleague improved it where he worked.

The methods are exactly opposite.

I give the placebo fix causal condition, while doing what would not be needed for them to know. I will only do that on assets we own and have best practices for.

When it's the latest multi-axis servo controlled foo-foo machine installed as some part of a complex business arrangement involving funding sources, grants, matching funds, etc....I replace fuses, reset overloads, rehome axises, make PLC edits, install load resistors, and of course the "It was a loose wire" problem solving choices. That's about it.

And I don't know about anyone else, but I loathe 24volt control systems! They are weak, hang up from dirty contacts, and generally suck. I prefer the good o'l 120V control systems that work every time without beating on them, blowing out door switches and auxiliary contacts, etc...
