Extreme Programming Refactored: The Case Against XP is meant to provide an independent look at Extreme Programming. It is meant to cut through the marketing hype of Extreme Programming and expose a number of weaknesses with this approach to software development. It tries to draw a distinction between true agility in a software process and fragility inherent in techniques such as oral documentation. Extreme Programming (XP) is a consummate mix of good goals, some good advice, and lots of bad advice. The goals and the good advice draw people in; the bad advice can potentially cause projects to fail. The XPers’ theory is that when applied together, this mixture of rules will somehow magically be safe. XP therefore represents a high-risk process, wrapped in a feel-good methodology. The marketing, hype, and earnest self-assurance of its authors will convince many project leaders to try out XP on their next project. In Extreme Programming Refactored: The Case Against XP into a more viable process, Rosenberg and Stephens are not attempting to define a new methodology, as there are plenty of those in the World already. Instead, they will be examining XP in the context of existing methodologies and processes such as RUP, ICONIX, Spiral, RAD, DSDM, etc - and showing how XP goals can be achieved using these existing processes (with a slight emphasis on RUP and ICONIX), using software wisdom that has been tried and proven to work again and again.
