Agile methodologies are a set of principles and practices designed to improve the way teams develop software. They emphasize flexibility, collaboration, and customer feedback, allowing teams to adapt quickly to changes. Instead of following a strict plan, Agile encourages iterative progress through short cycles called sprints, where teams can reassess their work and make adjustments based on user needs. One popular framework within Agile is Scrum, which organizes work into manageable chunks and promotes regular communication among team members. By focusing on delivering small, functional pieces of software frequently, Agile methodologies help teams respond to challenges and deliver better products more efficiently.
