Is There an Extreme World

Extreme Programming’s core concept is that the client’s requirements for a software system change throughout the system’s development. The iterative method that XP uses requires considerable client involvement and a deep level of commitment to complete discrete sections of the development while meeting all the documentation, testing, and quality requirements before deployment. This nontraditional development method sounds like a silver bullet—too good to be true. So, is anyone using it? Extreme Programming Installed sets out to show that this method has indeed seen realworld deployment. To understand the real-world implementation of these theories, we need practical examples to expand the ideas. This XP book provides them. Backed by experience on XP projects, Ron Jefferies, Ann Anderson, and Chet Hendrickson give insight into the practical issues that development teams face. For example, what do you do about programmers working overtime? How do you use XP on projects to replace legacy systems? One important theme in the book is that of constantly testing the code to ensure that it meets requirements. The authors give
