Windows: A Software Engineering Odyssey, a slide show from Mark Lucovsky, a Distinguished Engineer at Microsoft, discusses the Windows NT development and build process and some of the lessons they learned as they went from a small project (NT 3.1) to a huge project (Windows 2000). I suggest that you click the "Full Screen" link and view it that way to get all of the information.
"Compile time or run time bugs that occur in a developers office only affect that developer. Once a defect is checked-in, the number of people affected by the defect increases." (via Joel On Software)
