Agile methodology is an approach to project management that emphasizes collaboration, flexibility, and continuous improvement. It involves breaking projects down into smaller phases, called sprints, and working in iterations. Agile project management is an iterative development process, where feedback is continuously gathered from users and stakeholders to create the right user experience. The Agile Manifesto, published in 2001, outlines four values and 12 principles for Agile software development. The main benefits of using Agile processes in software development are the ability to shift strategies quickly, without disrupting the flow of a project, and the ability to quickly adapt to changing requirements. Agile methodologies can be used in software development and other types of projects. Agile frameworks include Scrum, Extreme Programming (XP), Lean, and Kanban. Agile is not defined by a set of ceremonies or specific development techniques, but rather a group of methodologies that demonstrate a commitment to tight feedback cycles and continuous improvement.
