Okay, mrsincere, I'll try to break it down further: Glenda was correct at one level, but incorrect in what she implied.

There is one chief officer for the UA system, the system president.

There is one administrative officer in charge of each UA university, the university chancellors. There is also one academic officer in charge of each UA university, the university provosts.

It is the norm for each separate university to have its own separate administrative and academic leaders, and it is the norm for a university system to have its own administrative leader who is not in charge of any individual universities within that system. (In fact, to do otherwise would raise serious questions.)

Glenda's error was implying the system and university levels should (or even can) be collapsed together.

I actually agree with Glenda that the UA system is administrator-heavy. However, to just throw around system and university titles as if collapsing them would solve the problem is irresponsible.
