Which development methodology uses fewer formal processes to deliver applications more rapidly?

The correct answer is Rapid Application Development (RAD) because this methodology emphasizes quick development and iteration over extensive and structured processes. RAD aims to produce functional prototypes quickly and encourages user feedback to refine features and functionality. By prioritizing speed and flexibility, RAD allows development teams to respond rapidly to changing requirements and user needs, which is crucial for environments where time-to-market is critical.

Agile Development also promotes rapid delivery but embraces an iterative process involving regular team reviews and adjustments throughout the software development cycle. While Agile includes formal practices like sprint planning and retrospectives, RAD focuses more on producing prototypes that can be modified based on user feedback with less emphasis on rigid processes.

Waterfall Development, in contrast, is a linear and sequential approach where each phase must be completed before the next phase begins. This method is characterized by extensive documentation and a formal structure, making it less suitable for rapid application delivery.

Extreme Programming (XP) is a specific type of Agile methodology that emphasizes high levels of collaboration, continuous feedback, and adaptability, but it still includes several formal practices, such as pair programming and test-driven development, which may slow down delivery compared to RAD.

In summary, RAD stands out for its focus on rapid prototyping and user involvement without the burden of extensive formal
