RAD, or Rapid Application Development, is a software development methodology that emphasizes quick prototyping and iterative feedback from users. This approach allows developers to create functional applications faster by focusing on user requirements and making adjustments throughout the development process. The key components of RAD include user involvement, prototyping, and the use of automated tools. By prioritizing collaboration and flexibility, RAD helps teams respond to changing needs and deliver high-quality software efficiently. This methodology is particularly useful in projects where requirements may evolve over time, making it a popular choice in the tech industry.
