The main advantage of the Agile approach to software development is its emphasis on flexibility and iterative progress. Agile methodologies allow teams to respond quickly to changes and user feedback by breaking down projects into smaller, manageable increments, called sprints. This process facilitates continuous integration and testing, which enhances product quality. Agile also promotes collaboration among small, cross-functional teams that work closely together, leading to improved communication and faster time-to-market. Overall, the Agile approach fosters a client-centered culture, ultimately delivering products more aligned with user needs.
