rad model in software engineering ppt

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.
