Agile is a set of principles and practices for software development that prioritize flexibility, collaboration, and rapid iteration. The Agile approach is designed to help teams respond to changing requirements and priorities and emphasizes the delivery of working software regularly. Agile teams work in short sprints, aiming to complete specific tasks or deliver a small functionality. This approach is intended to help teams deliver high-quality software more efficiently by allowing them to adapt to changing circumstances and respond quickly to new information.
