Testing and Turnover: The overall testing time is reduced in RAD model as the prototypes are independently tested during every iteration. However the data flow and the interfaces between all the components need to be thoroughly tested with complete test coverage. Since most of the programming components have already been tested, it reduces the risk of any major issues.



CHARACTERISTICS

  • It is a high-speed version of waterfall model

  • It is primarily for information systems application

  • Requirements are well understood by the user

  • Fully functional system is produced in a short time

  • It requires human resource and commitment

  • Separate teams can complete the functions and then integrated as a whole

  • The application modularized-major functions can be competed in 3 months.


ADVANTAGES

  • Reduced cycle time and improved productivity with fewer people hence lower costs

  • It encourages customer feedback

  • It increases reusability of components

  • The progress can be measured.

  • The customers are involved throughout the complete cycle which minimizes risk of not achieving customer satisfaction.


DISADVANTAGES

  • It depends on a strong team and individuals performance

  • Only systems that can be modularized can be built using RAD

  • It requires highly skilled developers/designers

  • There is high dependency on modeling skills

  • There is more complexity in management.
