Prototyping‚ (sometimes called RAD)‚ has opened up the application development process to end-users because it simplifies and accelerates systems design (Finance Magazine.com‚ 2015). These developments are becoming very popular because they have changed the role of end users and information systems specialists in systems development. Furthermore‚ it also helps analysts and users finalize the various interfaces and functions of large business systems (Marakas & O ’Brien‚ 2013). What are prototyping’s advantages
