> given appropriate documentation

Even with documentation you still get garbadge. I've had to decompile a HSM firmware to figure out what the actual input of functions was since the manufacturer kept claiming the documentation was correct. It wasn't even close. Only after I provided the solution to my own support ticket they changed the documentation (why bother paying for full support...).

I've gotten a bit of empathy for the poor front support guy since he'd have to keep complaining to the developers which kept saying "no it's fine as documented".
