Every business started for a reason and every business did so because
they felt they could offer people something that no other company was
able to. When a company first starts out they are more likely to keep
that idea close to them.
Everything they do will likely be centered on this very idea.
However, the longer a company exists the further they start to drift
from that idea. I have talked to people from companies before where I
quite literally asked them what it was that their company could do that
no one else could, and they just gave me a blank stare.
