Agile methodologies prioritize iterative development and responsiveness to change. A key strength is delivering functional software in small, frequent increments ("many small releases"), which allows stakeholders to provide early and continuous feedback.

This means the process is designed to accommodate evolving project requirements throughout the lifecycle, which is a significant advantage over the rigid, upfront planning of Waterfall.

A. Extensive documentation at each step is a characteristic of the Waterfall methodology, whereas Agile values working software over comprehensive documentation.
C. Fully understanding all elements before work begins is the foundation of the Waterfall model's "big design up front" approach, not Agile.
