So, maybe EFD could be used as a business front-end to a software modeling language like UML. The major resemblance with IDEF as a modeling tool indicates that it can be done. However, more research is needed to improve the EFD technique in such a way that formal mappings to UML can be made (see dashed line figure 1). Work of Kim et. al. [1] about the complementary use of IDEF and UML has contributed to the acceptance of IDEF as business-front end. A similar study should be done with EFD and UML.

==Conclusion==
Bringing the best of both worlds together and incorporate it in a clear Functional Software Architecture; this is one of the first objectives an organization has to reach when business process efficiency has to be improved. This rich schematic reference must be constructed by the right combination of methods and techniques in order to set detailed software specifications into the wider enterprise context. Figure 1 shows the methods and techniques that can be used or combined. Further research must reveal which combination is best in filling in the gab between business and software.
