Rapid Application Development (RAD) is a powerful software development tool. It is a more capable and faster process. Concept that products can be developed faster and of higher quality through:
- Gathering requirements using workshops or focus groups
- Prototyping and early, reiterative user testing of designs
- The re-use of software components
- A rigidly paced schedule that defers design improvements to the next product version
- Less formality in reviews and other team communication
Rapid Application Development is a software development methodology that involves techniques like iterative development and software prototyping. According to Whitten (2004), 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, 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”.
RAD approaches may entail compromises in functionality and performance in exchange for enabling faster development and facilitating application maintenance.
