Robert McLaws: FunWithCoding.NET - Windows Vista Edition : Windows Vista Bug Reports: An Analysis
This analysis, complete with pretty charts and graphs (I presume courtesy of Excel 2007, very nice) is a fascinating look at the bug reporting process for just the publicly accessible tools Microsoft has provided. I would love to see the data MS has internally.
This is not to bash Vista. I just find large engineering projects fascinating, and this is certainly one of the biggest, maybe the biggest in all of software. I am currently in the bug triage phase on a project and I am humbled by the monumental task MS must have of deciding what to fix and what not to fix to get Vista out the door.
