Reading the title, I thought it would be a post about TDD. I don't do TDD, I wish I had the time and resources and I am moving toward adding a more test-driven approach. Adding unit tests to my key libs allows me to move fast without breaking anything (for the key libs, our test suite is stupendously comprehensive). Of course, during new feature dev this luxury isn't always available. The next best thing is to do a phased rollout where our users become our beta testers. This works really well because users can switch to the non-beta version through the menu bar very easily. There are other strategies for moving fast without breaking stuff, but these two provide easy, big wins.
