Extreme Programming (XP) is an agile software development methodology designed for small to medium teams developing software in changing environments. It focuses on close communication between developers and customers, simplicity, feedback, and courage. Key practices include planning game, small releases, pair programming, continuous testing, refactoring, and collective ownership. XP pushes established software principles like communication, simplicity, and feedback to extreme levels. It was one of the earliest agile methodologies to challenge the traditional waterfall model.
