This document provides an introduction to eXtreme Programming (XP) and agile software development methods. It discusses some common problems with traditional software development approaches such as taking too long, costing too much, and requiring too many people. XP and agile aim to address these problems through principles like rapid delivery of working software in short iterations, frequent feedback, simplicity, respect, and flexibility. The document outlines XP practices like user stories, pair programming, test-driven development, and daily standups that embody these principles. It concludes by noting that agile methods have evolved over decades to become more effective approaches to software development.
