Extreme Programming (XP) is a lightweight methodology that enables small teams of developers to achieve breakthrough productivity and software quality, even when faced with rapidly changing or unclear requirements. In this new book, top object-oriented consultants James Newkirk and Robert Martin walk through an entire XP project, chronicling the adoption of XP by a team that has never used it before. Along the way, they show how to overcome the obstacles facing XP adopters, and present realistic XP best practices virtually any development organization can benefit from. The case study in this book is real, driven by the needs of a real customer. The artifacts, code, user stories, and anecdotes are all real, drawn from videotaped meetings throughout the project's development process. The result: an exceptionally true-to-life narrative, complete with mistakes and false starts, and reflecting the ebb and flow of a real project. For organizations considering XP, this may be the most realistic and useful guide ever produced. For project managers, developers, software engineers, XP customers, and upper-level managers.
