Agile is an iterative software development methodology with a goal centered around collaboration among self-organizing and cross-functional teams.
Processes used during agile typically employ disciplined and iterative project management practices in order to encourage frequent adaptation, engineering best practices, teamwork, and an alignment of goals. But perhaps the most-important advantage of agile is that it delivers value to customers faster. Projects are completed by combining smaller teams into cross-functional teams for open communication, collaboration, trust, and adaptation, reducing friction, breaking down silos, and facilitating shorter turnaround times.
In short, Agile empowers development teams with the ability to act and respond promptly, providing a better service to customers and a more-efficient and responsive solution for their organization.
