Same in general for companies. Internally, they are essentially tiny quasi-Communist (and generally secretive, isolationist and rather totalitarian) states complete with their own politburos, centralised top-down control and, theoretically, a common goal for all departments, the penalty for not buying into being exile. This changes pretty abruptly at the boundary of the company into almost the exact opposite: a marketplace where it's every company for themselves, there's no common goal, and resources, money and ideas both, are jealously hoarded by each entity behind thick silo walls. Obviously the analogy isn't perfect, but it's interesting how we're supposed to simultaneously operate in a much-vaunted capitalist context, but mostly interface to it through a thick layer of, basically, socialist systems.
