Software is uniquely different than other types of engineering because changes can be made almost immediately and even very late in the development process. Rapid application development rad is a software development method that uses minimal planning in favor of rapid prototyping. In vmodel the developers life cycle and testers life cycle are mapped to each other. Rapid application development thus enables quality products to be developed faster, saving valuable resources. The customer gets early visibility in the software. There is less longterm planning involved in the process, and more focus is paid to the adaptability of the development workflow.
Predictive teams in the traditional sdlc models usually work with detailed planning and have a complete forecast of the exact tasks and features to be delivered in the next few months or. Rapid application development rad is a form of agile software development methodology that prioritizes rapid prototype releases and iterations.
