When looking at the Agile Manifesto and the 12 principles,2 we can clearly see the ideology behind them. The main goal of Agile is to provide business agility and customer satisfaction, and that is achieved via close collaboration, iterative development, short feedback loops, and technical excellence. Methodologies like Scrum, Extreme Programming (XP), Dynamic Systems Development Method (DSDM), Adaptive Software Development (ASD), Crystal Methods, Feature-Driven Development (FDD), and other Agile methodologies are all means to the same end.
