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…
Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method
2007
Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…
Technology Architecture as a Driver for Business Cooperation: Case Study - Public Sector Cooperation in Finland
2019
The current premise in the enterprise architecture (EA) literature is that business architecture defines all other EA architecture layers; information architecture, information systems architecture, and technology architecture. In this paper, we will study the ICT-cooperation between eight small and mid-sized municipalities and cities in Southern Finland. Our case demonstrates that the ICT-cooperation is possible without business cooperation and that ICT-cooperation can be a driver for future business cooperation. The findings challenge the current premise of the guiding force of the business architecture and encourage organisations’ ICT-functions to seek daringly cooperation with other org…

Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review
2018
This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
Evaluation and measurement in enterprise and software architecture management
2008
Arvioinnit ja mittaaminen ovat osa jokapäiväistä elämäämme ja toimintaamme. Niiden perusteella tehtyjen tietojen ja havaintojen pohjalta teemme päätöksiä ja valintoja. Valitsemme esimerkiksi mitä vaatteita laitamme päälle, kuinka paljon tankkaamme autoon bensaa ja minkä taulutelevision hankimme.Yritykset keräävät mittareilla ja arvioinneilla tietoa omasta toiminnastaan, kuten kertyneistä työtunneista ja kustannuksista. Tiedon avulla seurataan toimintaa, ja sen avulla tehdään päätöksiä ja valintoja esimerkiksi siitä, kuinka paljon työvoimaa resursoidaan, mihin investoidaan ja mihin kehittäminen kohdistetaan.Rakennuksia suunnitellaan arkkitehtuurisuunnittelun avulla. Yhtälailla yritysten toim…
Enterprise architecture as a collaboration tool : discursive process for enterprise architecture management, planning and development
2008
Tieto- ja viestintäteknologiaa (ICT) hallitaan ja kehitetään kuten mitä tahansa yrityksen tai organisaation resurssia – tai ainakin näin olisi hyvä tehdä. Epäonnisia ICT-projekteja voidaan välttää nivomalla toiminnan ja teknologian suunnittelu ja kehittäminen yhteiseksi, vuorovaikutteiseksi prosessiksi, suosittelee aiheesta väittelevä Mirja Pulkkinen.Yritys- eli kokonaisarkkitehtuuri on kokonaisvaltainen lähestymistapa ICT:n hallintaan yhdessä liiketoiminnan kanssa. Johtamisessa voidaan tehdä tilaa liiketoiminnan ja teknologioiden vuoropuhelulle määrittämällä kokonaisarkkitehtuuriprosessi. Prosessi tuo toiminta-ajatuksen, tavoitteet sekä strategiat teknologiakehittäjille työn pohjaksi. Samo…
Key Issues in Enterprise Architecture Adoption in the Public Sector
2018
This paper examines the challenges of enterprise architecture (EA) adoption in public sector organisations. So far, demonstrating the benefits of EA has appeared difficult in this context, and the results in transforming public sector remain modest: Both the penetration and the maturity of EA appear rather low. In the academia, however, the adoption of EA has gained less interest than the EA development and methodologies. Hence, there is a need for research on what are the challenges of EA adoption, and how to overcome them. This paper presents the results of an expert survey on the challenges of EA adoption in the Finnish public sector. The analysis of quantitative data, supported with a q…
