Non-technical people don't know what normal is in your process, what should be noted when it's happening (Warning's may actually be important if non-fatal) and when they should seek advice. They're liable to ask you about every tiny thing, but then miss something really important altogether. Basically - I strongly disagree that you can often put a non-technical person onto a repetitive task involving technology.

It really depends what process you're talking about, but its a worthwhile consideration that unskilled (but intelligent) labor is not cheap either (i.e. Foxconn has to be massive and in another country to leverage it the way they do).
