Visual Flow Interface (VFI) is a generic management software tool for any user in different industries which is similar to implementing a Graphical User Interface (GUI) on Database Applications for the front end. VFI revolutionizes the principle of Management Information System (MIS) design and will launch a new generation of MIS. VFI's innovative contribution to MIS includes two key points: (1) A user's specific managerial and technological process is independent from the program of the MIS. Users can design their managerial and technologic process themselves or make any change freely without redesigning the program of the MIS; and (2) VFI focuses on the unique functional common character of different flows in all different industries and designs a visual image "Sandwich" to represent the functional common character. The Sandwich is a very simple idea but solves a very complicated problem for designing a generic MIS.
