Rapid Application Development (RAD) is a software development methodology that prioritizes speed and flexibility in the development process. It emerged as a response to the traditional waterfall model, which follows a sequential and rigid approach. RAD focuses on delivering software applications quickly by emphasizing iterative development, prototyping, and user feedback.
