Explanation:-

1)      RAD is modern software process that focus on a short development cycle.

2)      The RAD is “High speed” adaption then of waterfall model in which rapid development is achieved.

3)      As compared to waterfall model team size of RAD model is large to function with proper coordination.

4)      If requirement are well understood and project scope is considered, the RAD process is create a “Fully functionally system” within a very short period of time (normaly 60 to 90 days).

      Drabacks:

1.      RAD model needs enough human resources to create the required number of RAD teams.

2.      If developers and customers are not committed to the rapid model, the RAD project fails.

3.      Rapid-fire activities need to be completed in very short or small time frame. Time is

the major constraint in RAD.

4.      RAD has to be modularized in a proper way otherwise creates a lots of confusions and problems.

5.      In case of high performance requirement, RAD cannot be ideal model.

6.      Still if RAD model has to be used then it can be done by making tune between interface and    system components.
