Agile development is a project management approach that emphasizes continuous collaboration and improvement. It involves breaking the project into phases and following a cycle of planning, executing, and evaluating. 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 frequent iteration. Agile software development refers to a group of software development methodologies based on iterative development, where requirements and solutions evolve. Scrum, Kanban, Lean, and Extreme Programming (XP) are some of the popular Agile frameworks. The ultimate value in Agile development is that it enables teams to deliver value faster, with greater quality and predictability, and greater aptitude to respond to change. Agile development is important because it helps to ensure that development teams complete projects on time, improve communication between the development team and the product owner, and reduce the risks associated with complex projects.
