Rapid Application Development (RAD) model

Rapid Application Development (RAD) model

RAD model makes heavy use of reusable software components with an extremely short development cycle.
The RAD is a linear sequential software development process that emphasizes an extremely short development cycle. The RAD software model is a "high speed"

adaptation of the linear sequential model in which rapid development is achieved by using a component-based construction approach. Used primarily for information

systems applications, the RAD approach encompasses the following phases
§ Business modeling
§ Data modeling
§ Process modeling
§ Application generation
§ Testing
RAD process emphasizes reuse many of the program components have already been tested, which minimizes the testing and development time.
