You hit it on the head Jared. "if done properly".

Kevin,
In this case I would say that the change management implementation was
flawed.
We had quite comprehensive change management, but changes were not
difficult to make,
and emergency changes could be made the same day.
Change management is a good thing, if done properly.

Worse scenario I have ever seen was an organization that had

2) Storage Admin
3) Server Admin
4) Hardware Admin
5) Change Management Admin
Every time you wanted to get anything done you needed a weeks
notice and 10 meetings and entries in the change management system by
all departments involved in which any one of them being late on
responding caused the entire process to stall and possibly have to be
rescheduled.
Give me a situation with a DBA with authority to manage their
own servers from the hardware on up any day.

I think the key to situations such as Jared's was the "excellent
system administrators" comment. I've also had situations that were the
opposite of that. In the case where I deal with system/storage admins
of a more junior level, I certainly prefer to have as much control over
storage as possible, so ASM can be a good choice for that.

The main thing that is happening is that stuff
which used to "belong" in the realm of "root" and the Sys Admins are
being moved under the realm of DBA. So, there is a huge political
aspect to the adoption of ASM that often overshadows the technical
aspect, and this political "shift of power" from Sys Admin to DBA can be
more of an obstruction than any other aspect of ASM adoption. Not sure
what things are like in your shop, but that is not a trivial concern.
In addition to the political issues, there may also be
matters of convenience - yours.
At my previous employer I did not use ASM.
Whenever that topic came up, fellow DBA's felt obligated
to chastise me and attempt
to convince me to use ASM. Well that just wasn't going
to happen at that shop.
Why not? I was the only DBA.
That company has some excellent system administrators,
but they do not know Oracle that well.
I liked the fact that they could look at storage on the
server and monitor it and see where the space was.
As the lone DBA, I did not really want to 'own' the
storage.
Had I proposed ASM, I am quite sure the SA manager would
have shot it down when he learned the ramifications for his team,
and with good reason IMO.
