When I wrote the original posting, I talked about accountability. However, as I wrote it, I got it backwards. Accountability for the failures doesn't mean didly if you aren't also held accountable when it works properly. It is important to receive the credit!
So, who is still more important than what. However, it's not to know who to blame when it goes wrong, but who to reward when it goes right.
If you're being appreciated for the work you do, you'll make more of an effort on it. If you see it as a thankless task, you'll avoid it like a disease.
Essentially, I had the correct idea, but I was stuck in the blame side of the story. My bad.
