Reinterpreting TOGAF’s Enterprise Architecture Principles Using a Cybernetic Lens

In the literature, there are many definitions of Enterprise Architecture (EA), but most of them have three items in common: elements, relationships and principles. Among these, principles represent an essential element in the definition of EA, and some researchers posit that they are the main element in this definition. However, despite the recent advances in defining enterprise architecture principles (EAPs), this notion is suffering from the lack of a theoretical foundation that provides a logical framework for defining them. Stafford Beer’s Viable System Model (VSM) and its application to IT governance, the Viable Governance Model (VGM), have shown to be comprehensive blueprints for designing viable organizations and IT governance arrangements, respectively. Similarly, in recent realizations of EA, the design of the whole organization, and not just the IT, is brought into consideration. Therefore, this paper aims to establish whether the laws and principles of cybernetics, especially those embodied in the VSM and the VGM, can provide a sound theoretical basis for deriving EA principles. This paper investigates the principles defined in the Open Group’s TOGAF based on the theoretical concepts drawn from the VSM/VGM and cybernetics more broadly. This investigation demonstrates that the principles in TOGAF can be derived from the laws and principles of cybernetics.

The Social Dimension of Enterprise Architecture in Government

Citizens’ rising demands and expectations concerning both the quality and equality of public services are increasing pressure on the Finnish public administration to improve its efficiency and responsiveness. An enacted act on Information Management Governance in public administration declares Enterprise Architecture (abbreviated EA) as a central tool for developing administration’s services. EA is seen as a strategic management tool standardising the development of administration and exploitation of Information and Communication Technologies (abbreviated ICT). The new act demands agencies to apply EA yet there exists relatively limited knowledge and experience of the concept. Since EA is an abstract and complex tool there is great risk that the expectations put on EA are not met. The large numbers of agencies demanded to apply this tool increases the significance of the problem. This article is based on a case study research where the goal was to identify issues of EA use and adoption, to gain understanding why these issues exist and to recommend ways of improving the perceived value of EA. The focus was on the social dimension of alignment since most existing studies have emphasised the technical dimension. The study approaches the problem from the perspective of strategic management and organisational learning. EA is treated as a mechanism and a strategy tool to enable alignment of business and IT. EA adoption presents a learning challenge to an organisation – it has to learn the intellectual content but more importantly, it has to learn how to cooperate and share information across functional, hierarchical and professional boundaries.

Measuring the realization of benefits from Enterprise Architecture Management

Enterprise architecture management (EAM) has become an intensively discussed approach to manage enterprise transformations. While many organizations employ EAM, a notable insecurity about the value of EAM remains. In this paper*, we propose a model to measure the realization of benefits from EAM. We identify EAM success factors and EAM benefits through a comprehensive literature review and eleven explorative expert interviews. Based on our findings, we integrate the EAM success factors and benefits with the established DeLone & McLean IS success model resulting in a model that explains the realization of EAM benefits. This model aids organizations as a benchmark and framework for identifying and assessing the setup of their EAM initiatives and whether and how EAM benefits are materialized. We see our model also as a first step to gain insights in and start a discussion on the theory of EAM benefit realization.
