- Decisions continue to be an essential topic of utmost importance in every research field and era. However, while decision research has extensively offered a wide range of theories, it remains delved in the past, and needs robustness to sustain the future of data-driven decision-making, encompassing topics and technologies such as big data, analytics, machine learning, and automated decisions. Nowadays, decision processes have evolved, the role of humans as decision makers has changed and become inevitably intertwined with the support of machines, rationalities are no longer limited in the same way, data has become an abundant commodity, and the optimizing of decisions is not so far-fetched a tale as it once was in classical times. Accordingly, there is a dire need for new theories to support new phenomena. This paper aims to propose a modern data-driven decision theory, DECAS, to support the new elements of today’s decisions. Our theory extends upon classical decision theory by proposing three main claims: the (big) data and analytics should be considered as separate elements along with the decision-making process, the decision maker, and the decision; the appropriate collaboration between the decision maker and the analytics (machine) can result in a “collaborative rationality,” extending beyond the bounded rationality which decision makers were classically characterized by; and finally, the proper integration of the five elements, and the correct selection of data and analytics, can lead to more informed, and possibly better, decisions. Hence, the theory is elaborated in the paper, and introduced to some data-driven decision examples.

Opening Digital Archives and Collections With Emerging Data Analytics Technology : A Research Agenda
- 2017
-
In: Tidsskriftet Arkiv. - : ABM-media AS. - 1891-8107. ; 8:1
-
Journal article (peer-reviewed)abstract
- In the public sector, the EU legislation requires preservation and opening of increasing amounts of heterogeneous digital information that should be utilized by citizens and businesses. While technologies such as big data analytics (BDA) have emerged, opening of digital archives and collections at a large scale is in its infancy. Opening archives and collections involve also particular requirements for recognizing and managing issues of privacy and digital rights. As well, ensuring the sustainability of the opened materials and economical appraisal of digital materials for preservation require robust digital preservation practices. We need to proceed beyond the state-of-the-art in opening digital archives and collections through the means of emerging big data analytics and validating a novel concept for analytics which then enables delivering of knowledge for citizens and the society. We set out an agenda for using BDA as our strategy for research and enquiry and for demonstrating the benefit of BDA for opening digital archives by civil servants and for citizens. That will –eventually -transform the preservation practices, and delivery and use opportunities of public digital archives. Our research agenda suggests a framework integrating four domains of inquiry, analytics-enhanced appraisal, analytics-prepared preservation, analytics-enhanced opening, and analytics-enhanced use, for utilizing the BDA technologies in the domain of digital archives and collections. The suggested framework and research agenda identifies initially particular BDA technologies to be utilized in each of the four domains, and contributes by highlighting a need for an integrated “public understanding of big data” in the domain of digital preservation.

Why benefits realization from ERP in SMEs doesn't seem to matter?
- 2011
-
In: 2011 44th Hawaii International Conference on System Sciences. - Piscataway, NJ : IEEE Communications Society. - 9781424496181

Conference paper (peer-reviewed)abstract
- It is often argued that IT investments require active management practices for benefits realization. This applies also to enterprise resource planning (ERP) systems. As well, benefits realization efforts are assumed to create more value than they cost. Hence, the maturity of organizations should be increased and their cultures cultivated towards more rational benefits realization practices. Our study on ERP implementations in Egyptian medium-sized organizations, however, provides aberrant results that challenge the fundamental arguments for formal benefits realization practices. While investments in ERP are regarded as significant, and the projects challenging, formal benefits realization and investment evaluation practices are considered largely irrelevant. The reasons include the "self-evident" nature of ERP benefits, perceived difficulty and costliness of method use and suspicions on rationality of methods. A government policy to support ERP investments may also decrease incentives for further benefits optimization. Cost coordination of the implementation efforts, however, continues to be an issue

Diverging approaches to benefits realization from public ICT investments: A study of benefits realization methods in Norway
- 2013
-
In: Transforming Government. - : Emerald. - 1750-6166 .- 1750-6174. ; 7:1, s. 93-108

Journal article (peer-reviewed)abstract
- Purpose – The purpose of this paper is to explore practical methods for benefits realisation, with the intention of investigating if they are variance of a theme or rather can be classified as different approaches.Design/methodology/approach – Based on a document study of Norwegian methods-in-use, this study uses an analytical comparison following an assimilation-accommodation procedure to categorize the chosen methods as instances of approaches to benefits realisation.Findings – This study documents the emergence of several methods from practice in the last half decade. This analysis suggests the existence of three distinct approaches to benefits realisation and defines these according to their central features.Research limitations/implications – This is a document study that could have been enhanced byempirical data on first-hand experiences from the use of these methods. The findings of this study document a critical investigation of methods for benefits realisation, providing an enhanced base framework of three approaches for future research to build on.Originality/value – This study provides fresh perspectives on benefits realisation by suggesting that existing methods differ to an extent that the authors argue they belong to different approaches that are likely to cause quite different results in practical use. This has important implications for bothresearch and practice, as research should analyse benefits realisation efforts according to approach, and practice needs to carefully consider their choice of method based on their actual needs. Further, the paper employs an established analytical framework for a novel definition of approaches to the field of benefits realisation in the public sector.

Conference paper (peer-reviewed)abstract
- Benefits realization from public information and communication technology (ICT) investments is complicated. Research and development has resulted in methods for evaluating alternative business cases – and also more substantial methods to manage effects through an investment’s life cycle. Previous research suggests that use of benefits realization methods can lead to more informed decisions and implementations driven by benefits, this in turn can result in more realized benefits. However, there is a lack of studies of existing benefits realization methods-in-use. The objective of this article is to give an overview of the state-of-the-art of benefits realization method use in the Norwegian public sector, to highlight the variety of methods-in-use, and to discuss the different methods with reference to the much cited Benefits management model (Ward et al., 2006).

Conference paper (peer-reviewed)abstract
- Enterprise Resource Planning (ERP) systems influence organisational performance and business strategies significantly. However, identifying, managing, and realising expected benefits of ERP is challenging. The existing ERP research has largely focused on the implementation phase leaving post-implementation development understudied. Yet, post-implementation development ensures continuing benefits. This paper documents a single-case study on benefits realisation in post-implementation ERP development. The results imply that benefits realisation practices can improve job satisfaction while lack of it can lead to unused solutions. Outdated and evolved business processes, complicated further by workarounds, hinder on-going ERP development. Consequently, benefits realisation is hindered as well. Moreover, when subsidiaries are unable to identify new benefits on their own and while the benefits may even vary from one subsidiary to another, the complexity of benefits realisation increases. Altogether, the article highlights four empirical findings on issues influencing post-implementation benefits realisation and four issues on post implementation ERP development in general.

Modes of Collaboration in Digital Transformation of Municipal Wastewater Management
- 2021
-
In: ECIS 2021 PROCEEDINGS. - : Association for Information Systems.
-
Conference paper (peer-reviewed)abstract
- Digital transformation introduces new opportunities for public services, such as wastewater management. The opportunities include better interoperability and data availability, leading to such benefits as predictive maintenance and efficient allocation of resources. To reach the envisioned benefits, inter-organisational collaboration is essential. However, municipal water utilities have varying objectives, expectations, and challenges related to collaboration. This paper reports a field study on the digitalisation opportunities of municipal water services in Finland. We report the observed collaboration forms, rationale, expected benefits, and recognised challenges (i.e., the modes of inter-organizational collaboration) for deploying digitalised operations. This study provides insight into inter-organisational collaboration on the digital transformation of municipal water management. On a theoretical level, the study supports and complements the previously theorised collaboration modes of autonomous development, standardisation, and central service organization. The results also describe why and how limited company mode emerges in the sector, corresponding to the previously described consortium mode.

Toward Collective Ambidexterity in Public Sector Digital Initiatives: A Case of the Finnish Water Sector
- 2023
-
In: Digital Government: Research and Practice. - : Association for Computing Machinery. - 2639-0175. ; 4:4
-
Journal article (peer-reviewed)abstract
- The digital transformation era calls for digital innovations affecting the public sector, but such organizations often focus more on the efficiency and exploitation of current resources, ascribing less attention to explorative innovation. Innovation in new capabilities and technologies often require inter-organizational collaboration. In this context, public sector organizations do not operate in isolation—often engaging in interactions within their service sectors. While the contemporary literature on organizational ambidexterity primarily focuses on the balancing opportunities of a focal organization, radical sector-level development requires collaboration among various actors to achieve collective ambidexterity. Drawing on the research question of the influence of inter-organizational collaboration on the outcomes of digital initiatives, this exploratory case study on the Finnish water sector found that simultaneously operating modes of inter-organizational collaboration can facilitate different aspects of collective ambidexterity in an inter-organizational field and, consequently, the expected benefits from initiatives. Our theoretical contribution lies in demonstrating collaboration modes that can enhance specific aspects of collective ambidexterity. Accordingly, we suggest that collective ambidexterity through deliberately adopted modes of inter-organizational collaboration requires field-level facilitation in parallel with organizational ambidexterity. Furthermore, consequent practical implications for managing such collaborations are suggested for policymakers, interest groups, and the public sector.

Perceived Support in E-Collaborative Learning: An Exploratory Study Which Make Use of Synchronous and Asynchronous Online-Teaching Approaches
- 2012
-
In: Advances in Web-Based Learning - ICWL2012. - Heidelberg : Encyclopedia of Global Archaeology/Springer Verlag. - 9783642336416 - 9783642336423 ; , s. 11-20
-
Conference paper (peer-reviewed)abstract
- This study compares four different learning environments for e-collaborative learning in two European countries related to the dimension of student’s mutual support. The theoretical baseline is Vygotsky’s zone of proximal development (ZOPD) and the socio-genetic approach of Piaget. The analyzed data are based on questionnaires collected over the time period of an entire semester including four different courses at the master’s level. These courses applied different e-collaborative approaches including a variety of tools for supporting communication. It is assumed that these courses including communication tools e.g. virtual face-to-face meetings enhance the chances for better communication, and finally, for mutual support of students themselves. The objective is to investigate how the different environments have affected the students’ perception related to different e-collaborative learning platforms in the dimensions of social support, information exchange, and task support.
