Refactoring is the practice of continuously improving the usability, maintainability, and adaptability of code without changing its behavior. That makes it much easier to add new and unanticipated functionality. Refactoring has the disadvantage that it takes extra effort and requires changing the code. Any change has the potential to reduce the maturity and stability of the product, especially if you don't have adequate testing in place.
