I'm noticing a pretty awful trend in large companies especially lately where each section/department is completely cut off from all others, in the interest of hyper-specializing to increase efficiency or something like that. And so it's natural for people, having heard this enough to mimic it in an attempt to explain it to others. And I do appreciate that, don't get me wrong.
It's just that customer satisfaction is the duty and responsibility of everyone in the company, from the guy emptying wastebaskets in the lobby all the way up to the top brass. Everyone that is involved in the company, and especially those in positions dealing directly with the public are expected to put forth their best effort to improve customer satisfaction.
Playing the hyper-compartmentalization game doesn't really benefit anyone, and it's usually an impedance in the very area it's targeted at: improving efficiency of each department. So it's really just a way to buffer responsibility away from anyone in a position of responsibility. "Oh, can't help you there; not my department."
