Rapid Application Development (RAD) is a software development approach that aims to deliver high-quality software in a short period of time. It is based on the idea that it is better to build a working prototype of a software system and iteratively refine it, rather than spending a long time up front trying to design a perfect solution.
RAD typically involves the following steps:
RAD is often used in situations where time is a critical factor, such as when building software to meet a pressing business need or when there is a tight deadline. It is also often used when the requirements of the software are not fully understood up front and need to be refined through iteration.
Overall, RAD is a useful approach for building software quickly and efficiently, and it is widely used in a variety of industries.
