Rapid Application Development- RAD is a software development methodology that involves methods like iterative development and software prototyping. According to Whitten, it is a merger of various structured techniques, especially data-driven Information Engineering, with prototyping techniques to accelerate software systems development.

In Rapid Application Development- RAD, structured techniques and prototyping are especially used to define users' requirements and to design the final system. The development process starts with the development of preliminary data models and business process models using structured techniques. In the next stage, requirements are verified using prototyping, eventually to refine the data and process models. These stages are repeated iteratively; further development results in "a combined business requirements and technical design statement to be used for constructing new systems".

Rapid Application Development- RAD approaches may entail compromises in functionality and performance in exchange for enabling faster development and facilitating application maintenance.

Companies operating in a dynamic business environment are incessantly caught in a vortex of ever-changing market pressures and customer needs. To stay competitive, businesses have to make their systems more responsive by investing in time and cost-effective applications that help them address functional gaps and achieve business goals. Besides packaged software, businesses also require custom-built solutions to accommodate specific business needs and operational requirements.
