RAD is a linear sequential software development process model that emphasized on extremely short development cycle using a component-based construction approach. If the requirements are well understood and defined‚ and the project scope is constraint‚ the RAD process will enable a development team to create a fully functional system with in very short time period. RAD model has the following phases: Brainstorming. The proponents used brainstorming where they
