The term "agile" in project management methodologies refers to a flexible and iterative approach to software development. Agile emphasizes collaboration, customer feedback, and adaptive planning, allowing teams to respond quickly to changes throughout the development process. It involves breaking projects into smaller increments, known as sprints, which enable teams to deliver functionality regularly. Agile methodologies, such as Scrum and Kanban, promote continuous improvement and adaptability, enhancing the overall efficiency and quality of the final product.
