Enterprise Architecture management challenges in the Norwegian health sector

2017

Abstract Enterprise Architecture (EA) is instrumental to align ICT and business strategy, and many organizations carry out substantial efforts to implement EA. It is therefore seen as imperative to drive the digital strategy, identifying innovative new business models and technologies, and realizing more business value of technology investments. However, recent work suggest that it is a challenging task to implement enterprise architecture in an organization. This study explores the implementation of enterprise architecture (EA) in the Norwegian health sector. We found a number of challenges that impeded the process toward a common EA: unclear enterprise architecture roles, ineffective comm…

From Strategy to Code: Achieving Strategical Alignment in Software Development Projects Through Conceptual Modelling

2021

In this article we propose S2C, a strategy-to-code methodological approach to integrate organisational, business process, and information system modelling levels to support strategic alignment in software development. Through a model-driven approach and under the Conceptual-Model Programming paradigm, the proposal supports the semi-automatic generation of working software, as well as traceability among the modelling levels. Via a working example, we illustrate how strategic definitions can be traced into specific software components by the integration of three modelling methods: Lite*, for modelling strategic reaction to external influences, Communication Analysis, for business process mode…

Method Framework for Developing Enterprise Architecture Security Principles

2019

Organizations need to consider many facets of information security in their daily operations – among others, the rapidly increasing use of IT, emerging technologies and digitalization of organizations’ core resources provoke new threats that can be difficult to anticipate. It has been argued that the security and privacy considerations should be embedded in all the areas of organizational activities instead of only relying technical security mechanisms provided by the underlying systems and software. Enterprise Architecture Management (EAM) offers a holistic approach for managing different dimensions of an organization, and can be conceived as a coherent and consistent set of principles tha…

Scalable Deployment of Efficient Transportation Optimization for SMEs and Public Sector

2014

Transportation planning is central activity in logistic network design. In this study, we examine the deployment of optimization methodology to transportation planning. More specifically, we examine the adoption of system solving the well-known combinatorial optimization problem, the vehicle routing problem (VRP). Its application has resulted in efficiency gains in transportation logistics, but they have not been very widespread, and especially small-scale operators have not yet benefited from these systems. In this paper, we present a prospective case study on the issues during deployment of optimization, especially in the context of small and medium enterprises (SMEs). We propose a novel …

A reference architecture for archival systems with application to product models

2013

Nowadays, a major part of the information is in digital form. Digital preservation is essential to allowpeople to access information over time. From a computer science perspective, two major objectiveshave to be met to enable digital preservation: developing archival systems to manage the preserveddigital information, and select information representations that will facilitate the preservation. For complexinformation such as product models, these two objective are particularly hard to meet. Archivalsystems have to operate in a complex environment, interact with many different systems, and supportmay different business functions. Product model representations do not use all the possibilities…

Enterprise Architecture Descriptions for Enhancing Local Government Transformation and Coherency Management

2011

Local governments cover multiple service sectors and are typically organized into diversified, deeply hierarchical organizations. Public services offered are tangible, mostly non-IT-critical, and heavily dependent on human resources. Information management is mainly manual in strategy and management processes. In this case study of a large Finnish local government organization, enterprise architecture (EA) is proposed as a tool for improving the coherency of the local government and its alignment to IT and other resources. We ask, what kind of EA descriptions local government agencies need for coherency management, and how to organize them. We apply action design research principles at the …

Towards Ecosystemic Stance in Finnish Public Sector Enterprise Architecture

2019

Governments and organizations in both public and private sector are operating in fields of ever-growing uncertainty and complexity. To study this complex environment, the concept of ecosystems has been suggested, interpreting organizations as intertwined systems among layers of evolving ecosystems. While offering possibilities, operating in an ecosystemic environment might prove to be challenging, and the change from traditional governance structures might be difficult to manage, requiring holistic yet detailed view. Enterprise Architecture (EA) has been an interest of academics and practitioners for few decades, offering one of the most prominent solutions to managing complex organizations…

Defining Enterprise Architecture Risks in Business Environment

2008

First published in the proceedings of the EBRF 2007 conference ”Research Forum to Understand Business in Knowledge Society”, September 25-27, Jyväskylä, Finland Enterprise Architecture (EA) is a modern approach for managing and developing organizations and enabling them to tackle with the challenges induced by constant changes and increased complexity in their environment. However, as an extensive and strategically important program, EA is not without risks. Therefore, this exploratory study aims at providing an overview of generic risks that can potentially be related to EA in organizations, and at suggesting a classification scheme for the risks to facilitate their management. Data is col…

Evaluation of Enterprise IT Architecture Solutions – How can an ICT consultant tell what is best for you?

2003

ICT has become a key business enabler and a competitive factor for enterprises. Enterprise architecture, developed by ICT consultants and ICT end-user organizations, is emerging as the management tool for intertwined business and IT planning. For managerial decisions, there is a need to evaluate the business value of architecture development results, but only a few models for this have so far been presented. Here we present the V-model for EA testing and validation that marks the evaluation points in EA management, and guides which evaluation tools could be used. peerReviewed
