Right, it's always dependant on circumstances. I try to stress as much as possible that you always need to design things in such a way that even the dumbest, newest assembler will still be able to build it correctly. And often times we review drawings/instructions and find lots of poorly outlined procedures. But sometimes you get something like "The blue wire ran out, but I still had a bunch of light blue, so I just used that instead". It can be a killer.
