Agile software development is an iterative, incremental approach to developing and releasing software. Agile principles include commitment to timely and ongoing software deliveries, changing requirements, simplicity in approach, and sustainable development cycles. The Agile method also promotes self-organizing, self-empowered, self-monitoring teams and individuals who work collaboratively with face-to-face communication. Agile development practices include frequent releases, ongoing testing, customer and stakeholder participation throughout the development process, co-ownership of code, and pair-programming.
