Introduction Extreme Programming (XP) is a methodology of software development. Rather than a programming language XP represents agile software development. In fact, XP is the most important and most famous one of agile software development. It focuses on reducing the cost because of the changing demands. XPs supporters believe that compare to traditional software development methods, XP make people feel Extreme, but XP is more agile and is able to develop better software. The history of XP Extreme Programming was founded by Kent Beck, Ward Cunningham and Ron Jeffries in 1996. They proposed the Extreme Programming for the Chrysler Comprehensive Compensation System. In October 1999, Kent Beck wrote a book about XP. The name of book is Extreme Programming Explained. In 2005, in the second edition, author added more concepts of XP. So far XP is praised highly by more and more people. The concept of XP Goals XP attempts to reduce the cost of changes in requirements by having multiple short development cycles, rather than one long one. In this doctrine changes are a natural, inescapable and desirable aspect of software development projects, and should be planned for instead of attempting to define a stable set of requirements are among the activities (Extreme Programming, 2011). Activities There four main Activities in XP. Coding For XP, The really important thing only is coding in the software development process. XP advocates that two people write a program (PairProgramming) and cod
