Performing some heroics once in a while shows someone can be relied on. However, if heroics are the norm, it’s either bad work or bad management, and it should be looked at with some scrutiny.

I also find it more impressive when someone fixes someone else’s problem. I’m not one to shower praise on someone for fixing their own mistake, nor do I expect any praise if I fix my own mistake. I would be apologizing to everyone for screwing up in the first place.
