What I was told by some former employees from years ago is that people in other groups, even if they're your best friend, many times you don't hear a word about what they're working on until you have to integrate it and even then they may just give you an interface or something small and tell you your stuff has to work with it.

So even someone working with someone on this project may not even know that person is on the project.

Though surely some people do talk amongst themselves...

I've heard this before. Teams that build components used in every Apple OS (aka under Core OS) can be told to support platform X without knowing what X is or does.

XNU runs on everything from their Digital AV adapter[1], to the Mac Pro, to (I assume) the car.
