In the education sector, business and learning applications need to be modernized to meet an extended community of learners and other stakeholders. Service Oriented Architecture (SOA) prescribes a new way of building applications within a more powerful, flexible programming model, reducing development and ownership costs as also implementation risks. In this paper, we have proposed a technology...

The symbiosis between an enterprise architecture and service-oriented architecture results in so-called service-oriented enterprise architecture and brings up new problems for serviceoriented enterprise systems engineering. One of the most important is a business service quality definition, specification and evaluation. The paper proposes a formal model of enterprise business service quality ev...

Enterprise Architecture (EA) is a strategy that is employed by enterprises in order to align their business and Information Technology (IT). EA is managed, developed, and maintained through Enterprise Architecture Implementation Methodology (EAIM). Effectiveness of EA implementation is the degree in which EA helps to achieve the collective goals of the organization. This paper analyzes the resu...

Over the past few years, enterprise architecture management (EAM) has become increasingly popular in academia and in practice. One reason for this is that organizations seek to make use of various benefits that have been associated with EAM. However, researchers have stressed that EAM research has mainly focused on prescriptive frameworks and methodologies, whereas these concepts and associated...

Enterprise architecture management is considered a valuable means to guide the consistent design and evolution of increasingly complex information systems. Despite existing research on EAM methods and models, organizations often face serious difficulties making EAM effective. The paper proposes to take organizational culture as a highly aggregated construct describing the context of EAM initiat...

Enterprise architecture management (EAM) is expected to provide business value by guiding the continuous development and transformation of an enterprise. Based on the approach we strive for constructing useful artifacts that guide the successful and situational design of EAM. In order to do so we argue for a thorough analysis of the design problem in advance. This is realized by a two-step surv...

The purpose of EAM patterns can be seen to supplement existing EAM frameworks, which often only provide generic approaches in implementing, maintaining, and analysing an Enterprise Architecture. This is done by providing additional concepts, tailorable to the EAM problems at hand. This paper extends the existing EAM patterns approach of the Technical University of Munich by defining a concept f...

This paper introduces a formal framework for modeling and analysis of organizations. It allows representing a great variety of organizational concepts and relations that are structured into a number of dedicated perspectives (or views), similar to the ones defined in GERAM [3]. In contrast to many existing enterprise architectures the proposed framework has formal foundations based on the order...

In the last decades numerous developments and legal changes moved the utility industry towards a liberalized market. Utility enterprises have to stay competitive and reduce costs while managing more complex IT systems. The authors of this work see special demand for aligning business and IT for small and medium-sized enterprises (SME) in this industry and identify Enterprise Architecture Manage...

Enterprise Architecture Management (EAM) has become a prominent discipline for managing increasingly complex Business/IT relationships in organizations. The more tangible aspects of EAM like modeling, planning, principles or governance structures are widely discussed and understood. However, institutionalizing EAM in an organization remains a challenging issue. Therefore, actually realized EAM ...
