In software development, the term "agile" refers to a set of methodologies that prioritize flexibility, collaboration, and customer feedback. Agile practices involve iterative development where projects are divided into small, manageable units called sprints. This approach allows teams to respond rapidly to changes and continuously improve the product based on user input. Agile emphasizes cross-functional team collaboration, regular meetings, and adaptive planning, fostering an environment that encourages innovation and swift delivery of quality software in response to evolving market needs.
