Business Capabilities Centric Enterprise Architecture

In the field of Enterprise Architecture, The Open Group Architecture Framework (TOGAF) is a well known framework, that links Business Architecture, Data Architecture, Application Architecture, Technology. A key concept within Business Architecture domain is Business Capabilities, that are delivered by Business Component (BC). A BC is a business unit that encompasses a coherent set of activities, supported by assets including people, processes and technology. Current TOGAF version recognizes the BC requirements but misses how to bridge those requirements with a data, application and technology architecture. Defining the bridge is specifically the purpose of our extension called Business Capabilities Centric Enterprise Architecture (BCCE), where we adapt some TOGAF phases, extend the core TOGAF meta-model and add architectural contents. We have validated our approach on a telecommunication example taken from literature. A major benefit of the proposed extension is to link changes of business to data, application and technology architectures.
