What exactly is RAD?
rapid application development (RAD) is a software development methodology that uses minimal preparation in favor of rapid prototyping. A prototype is a working model that is functionally equal to a component of the item.
In RAD model the functional modules are developed in parallel as prototypes and are integrated to make the complete product for faster product delivery.
It makes it simpler to integrate the changes within the development procedure, since there is no comprehensive preplanning.
The most important feature for this model to be successful would be to ensure that the prototypes developed are reusable.
RAD Model Vs Traditional SDLC
The traditional SDLC follows a rigid process models with high emphasis on gathering and condition analysis before the coding starts. It gets a pressure on the client to sign off the conditions before the project starts and the customer doesn.t get the feel of the item as there’s no working construct accessible for quite a long time.
Some changes may be needed by the client after he truly gets to see the program, however the change procedure is very rigid and it may not be possible to incorporate important changes in the product in conventional SDLC.
RAD model concentrates on incremental and iterative delivery of working models to the consumer. This results in rapid delivery to the client and consumer engagement during the entire development cycle of merchandise reducing the risk of non conformance together with the genuine user conditions.
