Agile stands for "Agile software development." It is a set of methodologies and practices based on the Agile Manifesto, which emphasizes iterative, incremental delivery, flexibility, and collaboration between self-organizing, cross-functional teams.
The central idea behind Agile project management is the concept of "agility," which refers to the ability to move quickly and to easily adapt to changes. The word "agility" comes from the Latin "agere", meaning "to do" or "to act," and encompasses the capacity to make progress efficiently while also being able to change direction as needed.
