>How much developer time do you waste down the line because they have to fix the "working" code?
That is absolutely spot on. One of the hardest thing is explaining to management that the code your co-worker wrote in a "flash" three years ago is still eating up developer time today. We have a few ill-conceived or badly written systems that seems to eat up time and constantly interfere with new projects. The problems are pretty much invisible to management, because the developers spend a few hours here and there proppring up the badly written systems. Over time you end up having to spend all your time just putting out fires rather than helping the business moving forward.
