In computer control circles, the engineers who have to implement software that contains bugs sometimes have to explain to the software developers (vendors) that their perfect software isn't so perfect. The vendors sometimes try to convince the guy's using their stuff that a faulty algorithm isn't really a bug but rather a feature of their product.

So, us field engineers who have to figure out workarounds to the "features" to make our applications work sometimes sarcastically say "Remember, that code you needed to rewrite wasn't a bug ... it was a feature!"

Very few control software packages that I worked with from a vendor were perfect out of the box ... so that's one reason why field engineers get paid.
