Which RAD phase includes tasks such as data conversion, testing, changeover to the new system, and user training?

The RAD (Rapid Application Development) model emphasizes a quick and iterative approach to software development. The phase that includes tasks like data conversion, testing, changeover to the new system, and user training is crucial for ensuring that the new system operates seamlessly and users are adequately equipped to utilize it.

In the chosen phase, the focus is on taking the developed software and transitioning it into a live environment. Data conversion involves transferring and transforming existing data into a format compatible with the new system. Testing ensures that the system functions as intended, identifying any issues that need to be resolved before full deployment. Changeover encompasses the actual switch from the old system to the new one, an essential step in minimizing disruptions. User training is vital for helping end-users adapt to the new system and ensuring they know how to leverage its features effectively.

This phase is distinct from development, which is focused on building the system; from implementation, which may sometimes refer to the broader process including planning and coordination; and from design, which involves outlining the system's architecture and specifications. The clarity of responsibilities during the cutover ensures that a smooth transition occurs, minimizing the risk of problems that could arise from inadequate preparation or user unfamiliarity with the new system.
