For a long time, developers have known that the tools we use and the methodologies we practice have an effect on the quality of our software and our ability to delivery releases predictably. However, this is often a gut feeling based on anecdotal evidence with no numbers to support this theory. Wouldn't be cool to see actual numbers on how doing Code Quality analysis, Pairing Up and using tools for VCS and Continuous Integration significantly improve our ability to delivery quality software? Then look no further.
