Making the Case for Better Bugtracking Tools?

WeNeedBetterTools asks: "Help! I am trying to convince the leaders of my development organization that the quality of our bugtracking tool has a meaningful impact on the quality of products we produce. Right now, the tool we have is difficult to use because there is a high overhead to creating bugs, and they are very difficult to find in the system once they're reported. My main argument is that the easier the tool is to use, the more people will be motivated to enter bugs. My managers argue that if people aren't entering bugs, it's their own damn problem, and we ought to crack the whip until they always file every bug they possibly can. I need some solid references for my position. JoelOnSoftware has a great argument for making it simple to enter bugs, but he lacks credibility with my managers by virtue of the fact that he is also selling a bugtracking tool. Can anyone point me to any solid research on the relationship between the quality of bugtracking tool and the impact on product quality?"
