Overview

RAD Model(Rapid Application Development) is an incremental software development process model that allows usable systems to be built in as little as 60-90 days time frame. The RAD model is used for information systems development.

The RAD software development model contains the following phases::

• Business modeling
• Data modeling
• Process modeling
• Application generation
• Testing & Turnover

Pros

The pros of the RAD software development process model are as follows:

• Quick initial reviews are possible with this model
• RAD model involves constant integration, isolates problems, and encourages customer feedback

Cons

The cons of the RAD software development process model are as follows:

• This model requires a system that can be modularized
• This model requires highly skilled and well-trained developers
