<Ol> <Li> Requirements planning phase -- combines elements of the system planning and systems analysis phases of the Systems Development Life Cycle ( SDLC ) . Users , managers , and IT staff members discuss and agree on business needs , project scope , constraints , and system requirements . It ends when the team agrees on the key issues and obtains management authorization to continue . </Li> <Li> User design phase -- during this phase , users interact with systems analysts and develop models and prototypes that represent all system processes , inputs , and outputs . The RAD groups or subgroups typically use a combination of Joint Application Development ( JAD ) techniques and CASE tools to translate user needs into working models . User Design is a continuous interactive process that allows users to understand , modify , and eventually approve a working model of the system that meets their needs . </Li> <Li> Construction phase -- focuses on program and application development task similar to the SDLC . In RAD , however , users continue to participate and can still suggest changes or improvements as actual screens or reports are developed . Its tasks are programming and application development , coding , unit - integration and system testing . </Li> <Li> Cutover phase -- resembles the final tasks in the SDLC implementation phase , including data conversion , testing , changeover to the new system , and user training . Compared with traditional methods , the entire process is compressed . As a result , the new system is built , delivered , and placed in operation much sooner . </Li> </Ol>
