The software development methodology that emphasizes iterative progress is known as Agile. Agile methodologies advocate for breaking projects into smaller, manageable units called sprints, allowing teams to deliver functional components incrementally. This approach facilitates frequent reassessment and adaptation of plans, ensuring alignment with customer needs and changing requirements. Continuous feedback and collaboration among team members and stakeholders promote flexibility and rapid response to issues. Agile fosters a customer-centric environment and enhances project quality by encouraging ongoing improvements and ultimately leading to faster delivery times and more successful outcomes.
