LEAP: a precise lightweight framework for enterprise architecture.

This paper proposes LEAP: a simple framework for Enterprise Architecture (EA) that views an organization as an engine that executes in terms of hierarchically decomposed communicating components. The approach allows all aspects of the architecture to be precisely dened using standard modelling notations. Given that the approach is simple and precisely dened it can form the basis for a wide range of EA analysis techniques including simulation, compliance and consistency checking. The paper denes the LEAP framework and shows that it can be used to represent the key features of ArchiMate whilst containing fewer orthogonal concepts. We also show that the precision of LEAP, achieved through the use of OCL, can be used to verify both the claims made for inter-layer relationships in EA models and for extensions to ArchiMate

Synthesis of Business Motivation Model (BMM) and ArchiMate: Towards a New Modelling Technique for Strategic Alignment of Business and IT

While there is no dearth of studies on strategic alignment between business and IT, there is a lack of end-to end modelling techniques to depict such alignment. This paper presents a new modelling tech-nique, by synthesizing two leading modelling techniques – (a) Archimate – the tool proposed by The Open Group Architecture Framework (TOGAF) and the Business Motivation Model (BMM). The contribution of this paper is that it presents a new, end-to end modelling technique that can link the IT capabilities to the business strategy, thus depicting strategic alignment. Additionally, through this technique, the paper also presents a new comprehensive model to explain how an Enterprise Architec-ture framework (like TOGAF) can enable strategic alignment between business and IT

Motivation-oriented Architecture Modelling for e-Healthcare Prosumption

The enterprise architecture (EA) is a coherent and consistent set of principles and rules that guide system design. In EA modelling methods, an enterprise is identified with institution, business or administrative unit, a firm or an industrialized region. Enterprise architecture is also considered as strategic information assets, which determine the business mission, the technology necessary to perform the mission, the transitional processes for implementing new technologies in response to the changing mission needs. In this paper, the human i.e., stakeholders\u27 roles are emphasized as well as the motivation orientation in the enterprise architecture development is discussed. The following questions are formulated: who is the stakeholder of the EA, who is accountable and responsible for EA development, and what goals, constraints, and values are realized in the stakeholder activities\u27 processes for the organization mission and vision by example of e-healthcare prosumption system

Service Elements Valuation Using an Enterprise Architecture Language

This article defines a service as an architecture of processes, software and infrastructure elements for serving people. An architecture language therefore is a means to structure and analyze the values of service elements and the service as a whole. We provide a value-based perspective, which first includes a review of the concept of value in the context of service architectures for services. Here we conclude that multiple, even competing, values are at stake for different parts of a service. Second, the paper discusses a method for the valuation of a service using competing value constructs. We also demonstrate by a case how a formal architecture language can be used to calculate service values. Finally, the results are discussed and suggestions for further research are given

Model driven validation approach for enterprise architecture and motivation extensions

As the endorsement of Enterprise Architecture (EA) modelling continues to grow in diversity and complexity, management of its schema, artefacts, semantics and relationships has become an important business concern. To maintain agility and flexibility within competitive markets, organizations have also been compelled to explore ways of adjusting proactively to innovations, changes and complex events also by use of EA concepts to model business processes and strategies. Thus the need to ensure appropriate validation of EA taxonomies has been considered severally as an essential requirement for these processes in order to exert business motivation; relate information systems to technological infrastructure. However, since many taxonomies deployed today use widespread and disparate modelling methodologies, the possibility to adopt a generic validation approach remains a challenge. The proliferation of EA methodologies and perspectives has also led to intricacies in the formalization and validation of EA constructs as models often times have variant schematic interpretations. Thus, disparate implementations and inconsistent simulation of alignment between business architectures and heterogeneous application systems is common within the EA domain (Jonkers et al., 2003). In this research, the Model Driven Validation Approach (MDVA) is introduced. MDVA allows modelling of EA with validation attributes, formalization of the validation concepts and transformation of model artefacts to ontologies. The transformation simplifies querying based on motivation and constraints. As the extended methodology is grounded on the semiotics of existing tools, validation is executed using ubiquitous query language. The major contributions of this work are the extension of a metamodel of Business Layer of an EAF with Validation Element and the development of EAF model to ontology transformation Approach. With this innovation, domain-driven design and object-oriented analysis concepts are applied to achieve EAF model’s validation using ontology querying methodology. Additionally, the MDVA facilitates the traceability of EA artefacts using ontology graph patterns
