The "agile" methodology promotes principles such as iterative development, collaboration, and flexibility in software development. It encourages teams to work in short cycles or sprints, allowing for regular assessment and adaptation based on customer feedback or changing requirements. Agile emphasizes cross-functional teamwork, ensuring continuous communication between developers, stakeholders, and clients throughout the project lifecycle. This approach enhances responsiveness to change, reduces risks, and fosters a more collaborative environment, ultimately leading to higher-quality software and improved customer satisfaction.
