Enterprise Architecture Compliance: the Viewpoint of Evaluation
2008
First published in the Proceedings of the European Conference on Information Management and Evaluation (ECIME 2007), September 20-21, 2007, Montpellier, France Enterprise Architecture (EA) provides a holistic view of entire organization, including various viewpoints such as business, information, systems and technology. It is of interest for academics and practitioners alike. It has been suggested that EA is an approach for controlling the complexity and constant changes in the organization and its business environment, assisting organizations in realizing a multitude of positive business impacts. As the organization transforms from the current EA state towards the improved target state thr…
Enterprise Architecture Evaluation Components
2008
First published in the Proceedings of the 11th International HAAMAHA Conference July 9-12, 2007, Poznan, Poland Enterprise Architecture (EA) is a holistic view of an organization, including the viewpoints of business, information, systems and technology. It is stated to provide significant benefits to organizations, and is therefore of interest for both academics and practitioners. However, evaluating EA, or its benefits, is difficult. Moreover, the studies on EA evaluation are mostly inconsistent, and almost omit the planning aspect of evaluation. This study suggests the evaluation components that need to be addressed in EA evaluation planning, charted by a literature review supplemented a…
Analysis of the current State of Enterprise Architecture Evaluation Methods and Practices
2008
First published in the Proceedings of the European Conference on Information Management and Evaluation (ECIME 2007), September 20-21, 2007, Montpellier, France Today, more and more organizations adopt enterprise architecture (EA) processes to cope with the changing environment and to improve their performance and competitiveness. However, the evaluation of EA regarding its quality and benefits is rather difficult. The studies of previous research resulted in the recognition that there is no methodology for enabling the EA evaluation by considering the whole EA. Therefore, this paper presents and analyses the current state of methods and practices to evaluate EA from different viewpoints. Th…
Towards a Generic Evaluation Model for Enterprise Architecture
2008
First published in the Journal of Enterprise Architecture, Vol. 3, No. 3, 2007, pp. 9-16. Republished with the kind permission of the Journal of Enterprise Architecture During the past few years, enterprise architectures (EAs) have become one of the major interests of both business and information technology (IT) practitioners and academics. It has been suggested that EA is an approach for controlling the complexity and constant changes in the organization’s business environment. Research has mainly focused on the development and modeling of EAs, while the quality aspects of EA have only recently gained attention, especially in the form of EA maturity models. These models have been develope…
Potential Critical Success Factors for Enterprise Architecture
2008
First published in the Journal of Enterprise Architecture, Vol. 2, No. 4, 2006 pp. 29-40. Republished with the kind permission of the Journal of Enterprise Architecture During the past few years, enterprise architectures (EAs) have garnered considerable attention from both practitioners and academics in the fields of information systems and business management. It is suggested that EA is an approach for controlling the complexity and constant changes in the business environment of an organization. Research has mainly focused on the development and modeling of EA, while quality aspects of EA have gained less attention. The aim of this study is to provide insight into the critical success fac…
A Framework to Support Business-IT Alignment in Enterprise Architecture Decision Making
2008
First published in the proceedings of the EBRF 2007 conference ”Research Forum to Understand Business in Knowledge Society”, September 25-27, Jyväskylä, Finland Business-IT alignment is one of the key concerns of general management and chief information officers. It is commonly recognized as an important instrument for realizing organizational effectiveness. Achieving business-IT alignment requires often change in the way managers regard IT and it demands co-operation between general and IT management. The challenge of aligning business- and IT-related concerns and requirements in architecture decision making situations is the focus of this study. As one possible solution, we present a fram…
The long and winding road of enterprise architecture implementation in the Finnish public sector
2018
This thesis examines the implementation of enterprise architecture (EA) in the Finnish public sector. EA is a systematic approach for analysing, visualising, developing and governing the functions and structures of organisations. It describes how organisations businesses, information and systems function as a whole. Research and practice have shown the implementation of EA is challenging and slow to advance. Finland provides a prolific area for research since the use of EA is mandatory in public sector, which is rare amongst countries taking a whole-of-government EA approach. In order to research EA as a method for systemic change, a suitable theoretical framing was necessary. The context, …
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…
Katsaus kokonaisarkkitehtuurin määritelmiin ja potentiaalisiin hyötyihin
2017
Tässä systemaattisessa kirjallisuuskatsauksessa tarkastellaan kokonaisarkkitehtuurin määritelmiä ja potentiaalisia hyötyjä. Kirjallisuuskatsauksen tavoitteena on selvittää, millaisia määritelmiä kokonaisarkkitehtuurille on 2000-luvulla annettu, ja mihin määritelmiin viimeisin kokonaisarkkitehtuuria käsittelevä kirjallisuus viittaa. Kirjallisuuskatsauksen tulosten mukaan kokonaisarkkitehtuurille on annettu lukuisia määritelmiä, ja myös viimeisin aihetta käsittelevä kirjallisuus viittaa useisiin eri määritelmiin. Kokonaisarkkitehtuurin määritelmiä tarkastellaan ja niistä esitetään ontologinen integraatio, jonka mukaan kokonaisarkkitehtuuri kuvaa tai on toimintaa, jossa kuvataan organisaation …
Systemic Management of Architectural Decisions in Enterprise Architecture Planning. Four Dimensions and Three Abstraction Levels
2006
This paper presents a process model for the management of architectural decisions in enterprise architecture planning. First, decisions are made at the enterprise level, with strategic business considerations on the enterprise information, systems and technology strategy and governance issues. The next step is to define the domains, to then go on with domain architecture decisions. At the systems level, the enterprise and domain architecture decisions are collected and converted into architecture descriptions accurate in precision, form and detail to be given as input to the information systems development process, following the architectural planning. The model is derived from previous wor…
