Agile

Agile is a software development methodology that emphasizes iterative, incremental delivery of working software, constant customer collaboration, and responding to change. The goal of agile is to build software that meets customer needs and adapts quickly.

Agile teams work in short cycles called sprints, usually 1-4 weeks long. In each sprint, the team plans work, builds features, tests them, and reviews progress with stakeholders. At the end of the sprint, working software is delivered. Feedback gathered during the sprint helps plan the next sprint. This iterative approach allows teams to adapt plans based on changing requirements and lessons learned.

Popular agile frameworks include Scrum, which uses fixed-length sprints and daily standups, and Kanban, which focuses on limiting work-in-progress. Agile requires close collaboration between business and development teams. It works best with modular architecture, test automation, and continuous integration/delivery. Benefits of agile include faster time-to-market, improved team productivity, and software better aligned with business needs.
