As the boundary of an enterprise is extended, it becomes increasingly important that a common “big picture” of needed [[business]], people and IT system activities is developed and shared by all the parties involved [1]. A Functional Software Architecture does this by breaking down the organisation in business functions and corresponding IT needs. In this way the enterprise engineer provides a rich schematic reference that can be used by the software engineer in the development of these IT-systems.

==Development of a FSA==
Line 15 ⟶ 16:
At the top-level it shows the Enterprise Engineering field. Optimizing the internal and external business processes through process reengineering is one of the main objectives an enterprise can have in times of high external pressure. A business process involves value creating activities with certain inputs and outputs, which are interconnected and thereby jointly contribute to the final outcome (product or service) of the process. Process reengineering covers a variety of perspectives of how to change the organization. It is concerned with the redesign of strategic, value adding processes, systems, policies and organizational structures to optimize the processes of an organization [2]. This paper considers process (re)engineering as part of the broader enterprise engineering field.

==Modeling the business==
Line 66 ⟶ 69:
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==
Line 71 ⟶ 75:
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.
