Which of the following are examples of iterative development models?

The Rapid Application Development (RAD) model and Agile development model are both prime examples of iterative development models.

Iterative development involves breaking down the software development process into smaller, more manageable segments, allowing teams to refine and improve the product through repeated cycles or iterations. This approach enhances flexibility, accommodates changes, and provides opportunities for continuous improvement based on user feedback and testing results.

In the case of the RAD model, it emphasizes rapid prototyping and quick iterations, allowing for quick adjustments and enhancements based on user interactions. This responsiveness is characteristic of iterative development.

Similarly, the Agile development model is fundamentally iterative. Agile focuses on delivering small, incremental improvements to the software through iterative sprints. This adaptability to change and engagement with stakeholders throughout the development lifecycle is a hallmark of iterative methodologies.

Other options mentioned include models that do not fundamentally embrace the iterative approach, such as the Waterfall model, which follows a linear, sequential design process. This structure does not support the iterative nature associated with RAD and Agile, thereby reinforcing the selection of RAD and Agile as the correct examples of iterative development models.
