Ecosystem Architecture Management in the Public Sector : From Problems to Solutions
2019
Based on our research concerning enterprise architecture (EA) in the Finnish public sector, we discuss how EA concept and tool need to be developed to support government business ecosystem and organization design. Our research context indicates, beyond a federal government or a state one, that even a single municipality, like a city concern, can be perceived as an ecosystem of its sectoral domains, subsidiaries and such. We outline a vision of an overall ontology-based, shared EA repository for the-whole-of-government current state descriptions and specify the central design principles and functional requirements for such a system, illustrating some potential use cases of it. Based on inter…
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
Exploring the Critical Success Factors in Social and Health Care Information Systems Project Procurement
2020
A welfare reform involving the mixing of social and health services is being introduced by the Finnish government. Several factors have been identified for this shift, the most relevant of which is that many information systems are not interoperable and data-related problems have been identified. Management and isolated offers of service. Digitalizing to solve these issues is part of the government’s policy. This paper outlines the change landscape and explores the architectural options of the proposed digitalisation process and crucial success factors. The Undertaking The design is applied to the largest county, which consists of over 1,900 information systems related to social support and…
Enterprise Architecture Adoption Challenges: An exploratory Case Study of the Norwegian Higher Education Sector
2016
Abstract IT is a challenge to implement Enterprise Architecture (EA) in an organisation. This is also the case in the public sector, like public universities and colleges. There is a very limited research on such issues. It is therefore important to investigate how AE is implemented in various sectors, which benefits are realised and which challenges are most prominent. This interpretive case study investigates the efforts taken towards a common EA in the Norwegian higher education sector. We find that the progress was severely impeded by the lack of top level directions from the ministry, the lack of an overarching architecture council, and the lack of EA competence at the top management l…
Enterprise Architecture : A Perspective on How Far We Have Come, and Directions for the Future
2019
Enterprise Architecture (EA) appears to retain the attention of both practitioners and researchers, as the technological complexity of organizations grows. Several researchers have noted that research on EA has been diversifying over time, leading to inconsistent use of terminologies. Further, the benefit claims and other results, rather frequently, are not based on empirical evidence. These shortfalls in research on EA impede EA from maturing as a discipline and from demonstrating its benefit claims. Although there are reasons to believe that the research on EA has progressed, the extent of the progress and the directions for future research are not evident. This study draws on a meta-revi…
Managing information security in a business network of machinery maintenance services business – Enterprise architecture as a coordination tool
2007
Today, technologies enable easy access to information across organizational boundaries, also to systems of partners in business networks. This raises, however, several complex research questions on privacy, information security and trust. The study reported here provides motivation and a roadmap for approaching integrated security management solutions in a business network of partners with heterogeneous information and communication technologies (ICT): Systems, platforms, infrastructures as well as security policies. Enterprise architecture (EA) is proposed as a means for comprehensive and coordinated planning and management of corporate ICT and the security infrastructure. The EA approach …
Information Systems Students’ Impressions on Learning Modeling Enterprise Architectures
2020
This Full Research Paper presents enterprise architecture (EA) modeling tools utilized in an educational context. EA is a well-known and a commonly used approach for organizational development aiming to improve the alignment of business operations and information technology. This high level design of information technology (IT) driven business operations lays the foundations on lower level technical activities such as the design and implementation of application programs and features, system boundary interfaces, database distribution and data pipes, and system recovery. Organizations’ architectures are made visible by creating EA artefacts, such as business process diagrams, data models and…
Overview of Telecom Operator Software Market
2009
Telecommunications is an essential enabler of modern societies and a global vertical industry, providing communication and information services, with its annual revenue of over trillion euros. In this book, a company providing these services is referred to as a telecom operator or communications service provider (CSP). CSPs create value by offering connectivity to and via an infrastructure of networks for transferring signals. The core business processes in a telecom operator company therefore revolve, on one hand, around physical networks and their maintenance, and on the other, managing their customers and their use of the connectivity services over the networks.
Towards the design of an agile enterprise architecture management method
2016
Enterprises engage in dynamic environments and do need capabilities that will enable them to (re)configure and integrate existing capabilities or create new capabilities in order to remain viable and competitive in such environments. Enterprise Architecture (EA) by definition has the propensity to contribute to the agility of the enterprise in turbulent environments provided it is managed and guided by a methodic approach in a way that strengthens the capabilities with which the enterprise senses and responds to changes in its environment. However, the agility of the Enterprise Architecture Management (EAM) func-tion and its relation with the agility of the enterprise as a whole has been sp…
The Quest for Underpinning Theory of Enterprise Architecture - General Systems Theory
2017
Enterprise architecture originates from the 1980’s. It emerged among ICT practitioners to solve complex problems related to information systems. Currently EA is also utilised to solve business problems, although the focus is still in ICT and its alignment with business. EA can be defined as a description of the current and future states of the enterprise, and as a change between these states to meet stakeholder’s goals. Despite its popularity and 30 years of age, the literature review conducted on top information and management science journals revealed that EA is still lacking the sound theoretical foundation. In this conceptual paper, we propose General Systems Theory (GST) for underpinni…
