One of the major drawbacks of traditional computing is that it casts business processes in concrete, in other words in hard to change hardware and software. By modularizing systems into client and server portions, new technology and new software components can be added more easily without affecting the rest of the system, as well as altering the user perception of the interface. On the other hand, microcomputer based interfaces provide low cost of entry and relative independence from centralized information systems (IS) operations. Modern graphical user interfaces and menu selection by mouse clicks have become the common method for working with pulldown and pull up menus, in addition to dialogue boxes containing radio buttons, object boxes, text entry fields, and scrollable list of choices. The graphical environment allows more information to be conveyed in the menu through the use of modern graphical user interfaces as compared to mainframe based static interfaces. The usability test conducted by Burkhart, Hemphill, and Jones (1994) comparing a static based user interface to a GUI interface showed an improved performance of 56% over static based user interface.
