Yet, municipalities typically operate their ICT independently with only limited resources. Limited resources are a key incentive for inter-municipal ICT cooperation. We investigated, how inter-municipal ICT cooperation was executed and governed in 20 Finnish municipal regions including 144 actual municipalities. As the theoretical background, we reviewed Transaction Cost Economics and the Resource Based View theories, and the literature on IT governance practices. These theories and literature were used to identify theory-proposed ICT cooperation benefits and governance practices. We then compared theory-proposed benefits and practices empirically to those perceived in the actual regions. Finally, we used Granovetter’s social network theory to understand the empirical findings on ICT cooperation benefits and IT governance practices. Our find...

Despite of this, ISDM selection has received limited attention in earlier research. This raises the question are ISDM selection decisions rare in practice as well, and if so, what are the reasons. We used the bounded rationality and functional stupidity theories to investigate ISDM selection decision- making behavior, and interviewed 31 IS professionals working in the borderline between IS clients and suppliers. We examined their experiences about ISDM selection within both types of organizations. We discovered that the ISDM selection decisions of ISD projects are seldom discussed, that the ISDM selection behavior of client and supplier organizations differ, and that the bounded rationality and functional stupidity theories are descriptively useful. In addition to these research contributions, our study shows that there are theoretical and practical reasons to develop better ISDM selection guidelines for ISD projects

Muutokset ovat todennäköisesti vähintään yhtä suuria tulevien 25 vuoden aikana vuoteen 2040 mennessä. Kansantaloustieteen rahateorioiden kuvaamat rahan tehtävät ja maksupalvelumarkkinoiden osapuolten muodostaman maksamisen ekosysteemin intressit vaikuttavat kuluttajien maksamisen muutoksiin. Muina vaikuttavina tekijöinä artikkelissa tarkastellaan kuluttajien merkityksen kasvamista, mobiili- ja biometristen teknologioiden vaikutusta, Bitcoinin kaltaisia kryptovaluuttoja sekä tiedosta maksamista tietoräjähdyksen seurauksena. Digitaalisen tiedon määrä voi jopa kasvaa jopa yli 33 miljoonaa kertaa nykyistä suuremmaksi vuonna 2040. Artikkelissa ennakoidaan älymaksamisen kehittymistä uudeksi maksujärjestelmäksi mobiiliteknologioiden, biometristen teknologioiden, tiedosta maksamisen, kryptovaluuttojen sekä robottien ja ohjelmoitavien automaattien perustalle. English Abstract Payment services, instruments and methods used by consumers have changed almost entirely during the last 25 years, from the year 1990 to the year 2015. This has happened both for payments made at the point of sales and for remote payments. Changes will most likely to be at least equally significant during the next 25 years up to the year 2040. The roles of money depicted in economics, in the various money theories, as well as the interests of the payment service market actors will have influences on changes in consumers’ payment behaviour. This article addresses as the other influencing factors the growing power of consumers, the impacts of mobile and biometric technologies, crypto currencies such as Bitcoin, and payments for data services, which are expected to emerge as the result of data explosion. The volume of digital data could increase by as much as over 33 million times over its current volume by the year 2040. This article anticipates that smart payments will emerge as a novel payment system. The basis of the smart payments will constitute of mobile technologies, biometric technologies, payments for data services, crypto currencies as well as robots and programmable automatic devices.

As the owner of the data about him-/herself, a patient has the right to get and inspect all basic, treatment and other data recorded about her/him. However, this data is typically in the form of inconsistent data entries, such as medical reports, x-ray and other images, blood test admission notes and results, medication history and diagnoses, and is provided to the patient “as is”. The structure, format and meanings of these data entries differ enormously. Thus, when a patient is given access to all data stored about her/him, (s)he usually lacks capabilities and tools to handle the data, and to use the data for her/his benefit. Still, patients are expected to be able to act on the basis of the data available to them, for example, to make appointments or to bring laboratory test results with them. In a previous study, we made the data of similarly different medical and patient ISs interoperable to the cancer specialists of breast cancer cases by using shared attributes as the linkage between data storages. In this conceptual article, we apply our federative approach to contemplate from the patient’s point of view, how data available to a patient could be made interoperable. We explain the theoretical background of the federative approach and related tools within the mentioned breast cancer case and in general. We then describe how the federative approach could be used in the context of digitalized citizen/patient services, empowered citizens and patient/citizen-centric care. With this article we contribute to research by developing the federative approach further and by explaining how (medical and patient) data can be made interoperable to patients/citizens. Our results suggest means to support citizens and digitalized healthcare service intermediaries as well as patient empowerment.

Yet, this claim has proved hard to verify with empirical data. In this study we first identified and analyzed factors that are seen to influence IT deployment success, then hypothesized about the relationships among and between these factors and finally integrated the hypotheses into a research model. We then empirically evaluated the hypotheses and the entire research model. The consistency of IT investments as the response to the cyclical behavior of the economy is a novel factor introduced in this study to the ITBV research. Special attention was also placed on the perceived importance of IT to business, business-IT alignment and IT management. We used survey data of 212 responses collected from CxOs during an economic recession to test the hypotheses and the model for path coefficients and indirect effects.
Empirical results confirmed that all research model factors influenced positively IT deployment success. Moreover, high values in the perceived importance of IT, business-IT alignment and the quality of IT management were discovered to be antecedents to the consistency of IT investments, and when that was achieved, the impact was positive on IT deployment success.

The framework builds on the integration between the structural and processes perspectives of IT governance, business-IT alignment, and senior executives' needs. The framework is aimed to help board members, general managers, business line and IT executives to understand, measure, and manage IT governance in their respective organizations as a part of corporate governance. In the paper, special attention is paid to the conceptual validation of the framework and respective assessment instrument.

Rather than adding new variables, we attempted to reduce them to a more generic model. First, we identified potential factors, hypothesized about the relationships between the factors and then integrated the hypotheses into a research model. In addition to project level factors, we identified IT, business, and environment level factors. The model is thus multilevel but also integrative as it hypothesizes about the relationships between the model factors. Finally, we empirically evaluated the hypotheses and the research model. We used survey data of 249 CxOs for the empirical evaluation. Results confirmed that the research model factors contributed directly and indirectly on the success of IT projects. According to our findings, a favorable financial situation, highly-perceived importance of IT, and good IT and IT project competencies have especially significant positive impacts on IT project success.

Benefit expectations have impacted the rapid usage increase of this technology. We investigated with a five-year longitudinal survey changes in the expectations regarding cloud computing. We also crafted an integrated multilevel model to understand how cloud expectations and cloud readiness influence cloud computing deployment and performance combined with five IT business value (ITBV) factors. We tested empirically the crafted hypotheses and the research model using survey data collected from approximately 200+200 randomly selected business and IT executives in 2014 and 2015. Empirical results confirmed that our research model explained approximately one half of cloud computing performance for both years.
