In this second introductory chapter, well take a brief look at the XP values and practices as background for how we approach things in the rest of the book.
While this isnt a book about Extreme Programming, it is a book about what an XP practitioner does. Some of what well see here is right out of the XP body of knowledge, and some comes from the general knowledge we all build up over the yearsin my case, over many years .
Team members on XP projects are expected to do the same: to use the specialized XP values and practices and to blend these thoughtfully with all the other skills that they have. And if that isnt enough, were expected to learn and apply new skills as we go. That, in fact, is the topic of this book: how we can build useful software in a situation where we have a lot to learn.
