Agile is a software development methodology that emphasizes flexibility, collaboration, and customer satisfaction. Unlike traditional waterfall models that follow a linear, sequential approach, Agile breaks projects into small, iterative cycles called sprints, which typically last two to four weeks. Teams work on specific features or improvements during each sprint, allowing them to respond quickly to changes and incorporate feedback from stakeholders throughout the development process.

Agile promotes close collaboration among cross-functional teams, continuous improvement, and frequent delivery of functional software. The methodology is underpinned by the Agile Manifesto, which prioritizes individuals and interactions, working software, customer collaboration, and responsiveness to change over rigid processes and documentation. As a result, Agile has become a popular approach for organizations looking to increase adaptability and reduce the time to market for their products.
