Something for the weekend…
5 Enterprise Architecture picks for the weekend (much more interesting than the launch of the Sun on Sunday!).

| Mapping the Enterprise Architecture Principles in TOGAF to the Cybernetic Concepts–An Exploratory Study | Although principles are a key concept in the definition of Enterprise Architecture (EA), they have not received the same degree of attention as other EA concepts. The notion of EA principles (EAP) 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. The purpose of this paper is to explore whether the principles of cybernetics can provide a theoretical basis for interpreting EA principles derived through practice. This paper maps the principles defined in the Open Group‘s TOGAF to theoretical concepts drawn from the VSM/VGM and cybernetics. The paper concludes by identifying possible shortfalls in the existing set of principles and the need to develop a theoretical framework to overcome them. | free .pdf download
An interesting read on Enterprise Principles and Cybernetics. |

Realizing the Benefits of Enterprise Architecture: An Actor-Network Theory Perspective |
There is growing interest among IT practitioners and academics in Enterprise Architecture (EA) as an effective response to increasingly rapid business, economic, and technological change. EA has been proposed as a path towards better achieving and sustaining stronger business-IT alignment and integration, cost reductions, greater agility, reduced time to market, and other important objectives. Yet there is little theoretical basis to explain how EA work can lead to such achievements; moreover, the creation of a holistic and resilient EA remains an elusive goal for most enterprises. In this paper we use concepts from Actor- Network Theory to highlight some important socio-political and socio-technical aspects of EA work in the context of complex organization situations. Specifically, we focus on such challenges as actor identification in EA negotiations, the importance of soft skills, integration and reconciliation of multiple EA representations, discovering hidden interests and reflecting them in EA representations, dealing with misalignments of interests, as well as creating an environment for continuous EA, and thereby enterprise, improvement. | A clear opportunity to apply VPEC-T and other Systems Thinking frameworks as outlined many times on this blog. |

Federated Identity Management systems in e–government: the case of Italy |
Federated Identity Management (FIdM) systems are at the heart of any online service in a public, private or hybrid autonomous cooperating system. This paper reviews and compares several existing approaches for building FIdM systems in the specific sector of e–government by showing Identity Management (IdM) schemes employed by several countries representatives of different realities by size, geographical location and Public Administration (PA) traditions. The paper analyses then the case of Italy by introducing the ongoing effort for defining and developing a nationwide e–government Enterprise Architecture to guarantee a flexible approach for integrated application services, respecting local and central administrations’ autonomy. The paper finally focuses on the FIdM aspects employed within the Italian Enterprise Architecture. | Behind a pay wall – cost 30euro.

| Using ArchiMate to design learning environment architectures |
A desire to customise and personalise learning experiences, combined with the rise of a number of The Open Group’s ArchiMate standard may help in that regard. It was designed to facilitate communication This paper will present a number of DLE patterns that illustrate the range of possible architectures. Both the |

| Incorporating the NATO Human View in the DoDAF 2.0 Meta Model | The NATO Human View is an additional viewpoint for an architecture framework that provides information on the human in the system. This paper represents the last of three papers describing the NATO Human View. The first paper described the development of the Human View by a multinational NATO panel [Handley and Smillie, Syst Eng 11(2) (2008), 156–164]. The second paper described a methodology to use the Human View data in a simulation model in order to demonstrate the impact of the human on system performance [Handley and Smillie, Syst Eng 13(1) (2010), 72–79]. This final paper describes a methodology to align the NATO Human View with the Department of Defense Architecture Framework (DoDAF) 2.0 Meta Model (DM2) in order to produce “Fit for Purpose” views. These views can be used to augment the standard sets of architectural products with human-centered information important to the system description. The alignment of the Human View with the DM2 also facilitates reconciliation of different interpretations of the Human View construct. | Free article.
