Rapid Application Development (RAD) is an incremental software process model that emphasizes a short development cycle, the RAD model is a "high-speed" adaptation of the waterfall model, in which rapid development is achieved by using a component-based construction approach. 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...
