Which of the following software development models can best respond to requirements changes?1 pointAgile modelsThe Waterfall modelThe V-model

Analysis of Software Development Models

1. Agile Models: Agile methodologies are specifically designed to accommodate changes in requirements. They emphasize iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. Agile allows for flexibility and adaptation at various stages of the project, making it highly responsive to change.

2. The Waterfall Model: The Waterfall model is a sequential design process, where progress flows in one direction—downwards like a waterfall. This model is less suited to respond to changes since requirements must be clearly defined at the beginning of the project. Any changes in requirements necessitate revisiting previous stages, which can be time-consuming and costly.

3. The V-Model: Similar to the Waterfall model, the V-Model emphasizes a sequential path of development with a corresponding testing phase for each stage. While it does promote testing and validation, it is also rigid regarding changes in requirements, which can complicate the development process if alterations are needed.

Final Answer

The Agile model is the best choice for responding to requirements changes.
