RAD Model

As the name suggest, RAD is the Rapid Application Development Model. This model is used for projects which has to be done in a fast pace and can be modularised.

The main advantage is that it is a very high speed waterfall model and hence the time is relatively short.

The main disadvantage is that since tha project is done in parallel between teams, if one team lacks technical skills, the project will be a flop.

The requirement analysis is done first and then the project is divided into modules. The design, implementation and testing are done for each module by different teams. Then the output from each module are integrated in the deployment stage.
