That's definitely a good distinction; that clients CAN tell you what they need by if you ask the right questions. Of course, one major constraint in large corporate/government development is not being able to speak directly to the people who will actually be using a system. I've often had the experience of spending months developing and producing a working system before being allowed to show it to any of the eventual users. While incredibly stupid and occasionally frustrating, this can make development much more interesting and challenging.
