What key feature does Rapid Application Development (RAD) focus on?

Long-term project planning
Extensive user testing prior to development
Frequent prototyping and user feedback
Structured project management tools

The correct answer is: Frequent prototyping and user feedback

Frequent prototyping and user feedback is indeed the key feature that Rapid Application Development (RAD) focuses on. RAD emphasizes the iterative development of prototypes and the active involvement of users throughout the development process. This approach allows developers to create functional versions of applications quickly, which can be tested and refined based on user input, leading to a more user-centered design. By prioritizing rapid iterations and incorporating user feedback, RAD aims to enhance the responsiveness of the development process and improve user satisfaction with the final product. This characteristic sets RAD apart from traditional development methodologies that may rely more heavily on rigid planning and extensive documentation before producing any functional software.
