RAD (Rapid Application Development) refers to a development life-cycle designed to give much faster development and higher-quality results than those achieved with the traditional life-cycle
“Rapid Application Development is a software development process developed initially by James Martin in the 1980s. The methodology involves iterative development, and the construction of prototypes. Traditionally the rapid application development approach involves compromises in usability, features, and/or execution speed. It is described as a process through which the development cycle of an application is expedited. Rapid Application Development thus enables quality products to be developed faster, saving valuable resources”. (James Martin 1992)
I.COMPONENTS OF RAD
User involvement is key to success
Prototyping is conducted in sessions similar to Joint Application Design (JAD)
Prototyping screens become screens within the production system
CASE tools are used to design the prototypes......
