the rad (rapid application development) model is based on prototyping and iterative development with no specific planning involved. a prototype is a working model that is functionally equivalent to a component of the product. the business model for the product under development is designed in terms of flow of information and the distribution of information between various business channels. the information gathered in the business modelling phase is reviewed and analyzed to form sets of data objects vital for the business. the process model for any changes or enhancements to the data object sets is defined in this phase.
the actual system is built and coding is done by using automation tools to convert process and data models into actual prototypes. however, the data flow and the interfaces between all the components need to be thoroughly tested with complete test coverage. however, the change process is quite rigid and it may not be feasible to incorporate major changes in the product in the traditional sdlc. the rad model focuses on iterative and incremental delivery of working models to the customer. rad model enables rapid delivery as it reduces the overall development time due to the reusability of the components and parallel development. rad works well only if high skilled engineers are available and the customer is also committed to achieve the targeted prototype in the given time frame.
it is a type of incremental model. the developments are time boxed, delivered and then assembled into a working prototype. business modeling: the information flow is identified between various business functions. data modeling: information gathered from business modeling is used to define data objects that are needed for the business. application generation: automated tools are used to convert process models into code and the actual system.

the rad (rapid application development) model is based on prototyping and iterative development with no specific planning involved. the process of writing the software itself involves the planning required for developing the product. of the waterfall model. sdlc rad model has 5 phases. it is a key model in software engineering. rad sdlc model should be chosen only if resources with high business knowledge are available and there is a need, . rapid application development (rad) describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery. the rad model is, therefore, a sharp alternative to the typical waterfall development model, which often focuses largely on planning and sequential design practices.
a software project can be implemented using this model if the project can be broken down into small rad approaches, on the other hand, recognize that software rad is a linear sequential software development process model that emphasizes a concise development cycle using an,
