The RAD (Rapid Application Development) model is based on prototyping and iterative development with no special preparation called for. The method of writing the applications itself demands the planning for developing the product required.
Rapid Program development concentrates on gathering customer requirements through workshops or focus groups, early testing of the prototypes by the customer using iterative notion, reuse of the present prototypes (parts), continuous integration and quick delivery.
What exactly is RAD?
rapid application development (RAD) is a software development methodology which uses minimal preparation in favor of rapid prototyping. A prototype is a working model that is functionally equal to a part of the merchandise.
In RAD model the functional modules are developed in parallel as prototypes and are incorporated to create the complete product for faster product delivery.
It makes it simpler to integrate the changes within the development procedure since there is absolutely no thorough preplanning.
The most crucial feature for this particular model to be successful would be to make sure that the prototypes developed are reusable.
RAD Model Vs Traditional SDLC
A rigid process models are followed by the conventional SDLC with high emphasis on gathering and requirement analysis before the coding starts. It gets a pressure on the client to sign off the conditions before the project begins and the customer doesn.t get the feel of the item as there’s no working construct accessible for quite a long time.
After he actually gets to see the software the customer may need some changes, yet the change procedure is fairly inflexible and it may not be feasible to integrate major changes in the item in conventional SDLC.
RAD model targets iterative and incremental delivery of working models to the customer. During the entire development cycle of product reducing the danger of non conformance together with the real user requirements, this results in quick delivery to the client and client engagement.
