Refactoring: A Conversation with Martin Fowler
Refactoring is about saying, "Let’s restructure this system in order to make it easier to change it." The corollary is that it’s pointless to refactor a system you will never change, because you’ll never get a payback. But if you will be changing the system—either to fix bugs or add features—keeping the system well factored or making it better factored will give you a payback as you make those changes.
