Most projects start from an existing code base – whether you are enhancing an existing app or rewriting an app to modernize it. In either case, the documentation for the existing system is most likely non-existent, stale or just wrong. The people who wrote the system are no longer available to the new team, which is left trying to understand a system with no starting point. See how Visual Studio 11 gives you that starting point and allows teams to be productive in a fraction of the time it takes today as well as ensuring that you have the tools to document the new work so you don’t end up with the same situation in the future.
