You raise a good point.

In my experience, upper management with enough years in the business do not feign as much authority in understanding how IT works. On the contrary IT people who have been with the business long enough seem to think they understand the business pretty well. They don't. And half knowledge is dangerous is indeed a wise saying.

So even though those system architects buzzing with their confidence due to years of being part of the business often provide helpful insight, i would always always run crucial decisions that effect the business functionally, by business people only.
