The final phase in the CoRAD methodology is product delivery. This phase has two parts : preparation and execution. During rollout preparation, a conversion strategy is developed if any conversion from an existing system is being done. This is followed by conversion program design and the development of the conversion programs. Rollout execution involves the complete installation of the application in the production environment for the extended user community.
Cambridge's CoRAD methodology is just one example of a rapid application development methodology. Like many methodologies, CoRAD is designed to be tailored to the individual projects where it is applied. No matter whether you use CoRAD, or your own version of a rapid application development methodology, your software project is more likely to be successful if some sort of RAD approach is followed.
