That's true, you can definitely over-correct. I guess if I was the supervisor in this case, I'd be doing some analysis with the developer after the fact. Were procedures correctly followed? If not, use this event as an example of why the procedures are in place. If they were followed, was it a brain-dead simple error? If so, then obviously there is something wrong with our test plans. If it was one of those errors that turned out to be a perfect storm of environment differences, unexpected inputs, code side-effects or what-have-you, then there probably is no quick solution and the imposition of some overbearing system to try to limit something that will probably not happen again would be overkill. It's always best to do an after action analysis to see where things broke down, I think. Changing procedures or adding protections might be warranted, as long as it's not the "get my permission before ever putting a Y in that field again" kind of enhancement.
