I read an interesting article this morning:

Microsoft Working Through Windows Vista Bugs

TechWeb- July 10, 2006

A Windows developer and consultant who analyzed a database of reported Windows Vista bugs says Microsoft has been quickly addressing bugs as they are submitted.

It's pretty amazing to see what people will do when you give them access to data.  We look at our ability to keep up with bugs pretty closely.  It's cool to see that scrutiny coming from yet another direction.

In Visual Studio 2005 SP1, we are able to see just how many of the bugs we fixed that are reported by customers.  We are starting to question why we introduced churn for any bug not reported by customers.
