Agile Development is an approach to software development that promotes continuous iteration and teamwork. Unlike traditional methods, agile focuses on delivering small, incremental changes that can be adapted based on feedback. This approach encourages iterative testing and development, regularly engaging stakeholders and incorporating their input. Agile methodologies include frameworks like Scrum, Kanban, and Extreme Programming (XP), each with its specific practices and processes aimed at enhancing team communication and delivering high-quality software more efficiently.
