Abstract  Enterprise architecture (EA) is present at every company; however, just few organizations have their architecture formalized and manage it to meet their strategic goals. EA creates opportunity for an effective interaction between business and ITC world. Moreover, EA serves as the blueprint for a company and the process which defines it. This paper formulates problem with current approach describing an enterprise and shows that service orientation is a key to coherent enterprise architecture description. We briefly discuss enterprise architecture cohesion and propose method how to measure the level of cohesion within enterprise architecture layers. Main contribution of this paper consists in a comparison and analysis of the chosen frameworks (ArchiMate, Zachman, TOGAF, and DoDAF) based on cohesion ­viewpoint. Conclusions made by authors could serve as guidance for particular framework extension with the aim to gain coherent enterprise description.

1  Introduction Pervasive globalization impacted businesses to be cost-effective and at the same time competitive and innovative. Organizations operate within a rapidly changing and evolving network of business partners, relying on state-of-the-art technology to facilitate their cooperation. Many enterprises have been heavily involved in effort to ­successfully manage this dependency. In recent years, several scientific papers were published and research done to describe the approaches and methods to solve the problem. These include the ICT1 assurance, risk management, increased requirements

for control and efforts to standardize ICT processes and services [2, 5], enterprise architecture approach, and enterprise architecture frameworks [6, 12, 16, 19]. However, organizations often fail to meet the business requirements [13], and a lack of harmonization and enterprise description coherence is considered as the key reason [3, 15–17]. Achieving alignment between all parts of the enterprise and integrated approach to all aspects of the enterprise is needed. Enterprise effectiveness is not obtained by local optimization, but is realized by well-defined interaction of organization components [6]. Enterprise architecture is an important tool to address whole-enterprise integration. Institute For Enterprise Architecture Developments’ definition of enterprise architecture states that it is “a complete expression of the enterprise; a master plan which “acts as a collaboration force” between aspects of business planning such as goals, visions, strategies and governan
