Agile is a project management and software development approach that emphasizes flexibility, collaboration, and customer satisfaction. It promotes iterative progress through small, manageable increments, allowing teams to adapt to changes quickly and efficiently. This methodology is particularly popular in software development due to its ability to respond to evolving requirements. The Agile framework encourages regular feedback and continuous improvement, fostering a culture of teamwork and accountability. By breaking projects into smaller tasks, teams can deliver functional components more frequently, ensuring that the final product aligns closely with customer needs and expectations.
