> I suggest everyone take a minicourse or read a book on systems engineering - at least the part where they discuss requirements. The fact that two distinct entities have an identical requirement for something does not mean there is one requirement. It means there are two requirements which (for now) happen to be identical.

I'd love to do this -- do you have any recommendations for a book like this?

Not really. I took it as part of an inhouse training at work.
