While each of the agile methodologies is unique in its specific approach, they all share a common vision and core values (see the Agile Manifesto). They all fundamentally incorporate iteration and the continuous feedback that it provides to successively refine and deliver a software system.
They all involve continuous planning, continuous testing, continuous integration, and other forms of continuous evolution of both the project and the software.
hey are all lightweight, especially compared to traditional waterfall-style processes, and inherently adaptable. What is more important about agile methods is that they all focus on empowering people to collaborate and make decisions together quickly and effectively.
