SoEA4EE 2016 - 8th Workshop on Service oriented Enterprise Architecture for Enterprise Engineering

Several developments, such as the success of cloud-computing show that not the ownership of IT resources but their management is the foundation for sustainable competitive advantage[1]. According to Ross et al.[2], smart companies define how they (will) do business (using an operating model) and design the processes and infrastructure critical to their current and future operations (using an enterprise architecture).
Enterprise Engineering (EE) is the application of engineering principles to the design of Enterprise Architectures. It allows deriving the Enterprise Architecture from the enterprise goals and strategy and aligning it with the enterprise resources as shown in Figure 1, Enterprise architecture aims (i) to understand the interactions and all kind of articulations between business and information technology, (ii) to define how to align business components and IT components, as well as business strategy and IT strategy, and more particularly (iii) to develop and support a common understanding and sharing of those purposes of interest. Enterprise architecture is used to map the enterprise goal and strategy to the enterprise’s resources (actors, assets, IT supports) and to take into account the evolution of this mapping. It also provides documentation on the assignment of enterprise resources to the enterprise goals and strategy.
There are different paradigms for creating enterprise architecture. The most important is to encapsulate the functionalities of IT resources as services, as shown in Figure 2. By this means, it is possible to clearly describe the contributions of IT both in terms of functionality and quality and to define a service-oriented enterprise architecture (SoEA). SoEA easily integrates wide-spread technological approaches such as SOA or emerging ones as cloud computing because they also use service as structuring and governing paradigm.
