The paper at hand addresses this research gap and presents an exhaustive literature review on the CIO research field using main path analysis. We identify the central papers in CIO research and eight main research streams by quantitatively and qualitatively analyzing 466 papers. We find that established research streams, e.g., ‘Evolving role of the CIO’ and ‘CIO hierarchical position and relationships’ as well as recently emerging research streams, e.g., ‘CIO as business enabler’ and ‘CIOs and IT security,’ draw growing attention. Based on our findings, we develop promising further avenues for research in the CIO field.

The Why of Cloud Computing Delivery Model Selection BT - Vignettes on the Post-Adoption of Cloud Computing T2 - Proceedings of the 54th Hawaii International Conference on System Sciences, 2021 N2 - Most large-scale organizations adopted Cloud Computing (CC) on a company level in recent years. Managers now face the challenge to appropriately implement CC "operationally", i.e., for information systems (ISs). We refer to this as post-adoption, addressing the extent of technology usage after adoption. Specifically, managers need to choose among the CC delivery models Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-asa-Service (SaaS). We differentiate the determinants of this post-adoption decision for IaaS, PaaS, and SaaS. Based on this analysis, we derive criteria that guide managers' delivery model selection: Adopt 1) IaaS for ISs requiring flexibility and reduced time to market, 2) PaaS to access specialized resources, and 3) SaaS to focus on core competencies. Moreover, we analyze the impact on the CC strategy and postulate them as recommendations: I) acknowledge the interplay between governance and time-to-market, II) realize cost savings on company level, and III) consider strategically important ISs for CC.

The adoption of servitized business models is a major business model innovation strategy. At the same time, digitalization drives the evolution of IT capabilities at these business models. Scholars argue that it remains unclear how IT capabilities enable servitized business models to build a competitive advantage by achieving cost advantages or differentiation. This paper explores IT capabilities that enable building a competitive advantage for servitized business models based on a qualitative analysis of multiple published case studies. The authors identify configurations of IT capabilities among servitized business models. The findings contribute to servitization research by exploring IT capabilities and how they are combined among servitized business models. The insights help practitioners deploy digital technologies and IT assets effectively as building blocks of IT capabilities to advance their servitized business model.

For this purpose, we conducted a series of qualitative, semistructured interviews with IS sourcing experts. The interview questions focused on the participants’ perceptions and experiences with the topic, on identifying reasons for and against IS backsourcing, and on revealing relevant trends pertinent to IS backsourcing. We then compared those findings with two previously conducted comprehensive literature reviews on academic and practitioner literature on IS backsourcing. By following this approach, we contribute to the existing research by verifying previous findings, for example, the most important reasons why companies decide in favor of IS backsourcing. Additionally, we were able to enhance previous contributions as we highlight the significance of differentiating between the scope of IS backsourcing by looking at the underlying services which are potentially backsourced. Further, we identified the importance of managers’ personal preferences as an additional reason for IS backsourcing, for example, based on personal experiences or a perceived need for change. Based on our findings, we created a comprehensive overview of all aspects connected to the IS backsourcing process and derived opportunities for further research to contribute to the IS backsourcing research agenda.

We conducted a longitudinal case study on the evolving CC strategy and its implementation at the multinational company Continental, based on a previous case study by Loebbecke et al. (2012). We narrate Continental's pathway towards CC adoption, which comprised the experimentation, professionalization, and utilization of CC, and discuss current and previous barriers encountered during the implementation. We derive five lessons learned that can serve as practical guidance for executives aiming to accelerate CC adoption within their own organization: (1) differentiate the CC strategy by delivery model; (2)drive proof of concepts to generate reusable blueprints; (3) preinvest in the integration of IaaS and PaaS providers; (4) implement CC gradually, transforming applications during the transition to the cloud; and (5) disseminate knowledge within the organization to enable change.

Consequently, companies are also revisiting their existing IT sourcing arrangements. In the article at hand, the authors explore the concept of IT backsourcing by presenting the results from a quantitative online survey with global IT practitioners. The authors confirm that backsourcing is frequently applied in practice, with key reasons being dissatisfaction with service or relationship quality and higher than expected costs. Further, the authors identify IT services with an increased likelihood of being backsourced, e.g., application development or data center, and discuss the effect of a CIO change on the backsourcing decision. In addition, the authors show that there are differences in the perceptions on the antecedents and the results of backsourcing decisions between management and operational level. The authors conclude with practical implications for IT managers based on their findings.

Die vorliegende Studie stellt die Ergebnisse einer Umfrage unter IT-Managern zu Einflussfaktoren von IT-Backsourcing-Entscheidungen vor. Es lässt sich feststellen, dass IT-Backsourcing von Unternehmen in unterschiedlichen Branchen und für eine Vielzahl an unterschiedlichen IT-Services, wie z. B. Applikationsentwicklung oder Infrastruktur-Leistungen, durchgeführt wird. Hauptgründe für die Entscheidung für ein IT-Backsourcing sind mangelnde Qualität, hohe Kosten sowie eine schlechte Beziehung zum IT-Dienstleister. Die Ergebnisse der Umfrage zeigen, dass diejenigen Unternehmen, die sich für ein Backsourcing entschieden haben, nach der Entscheidung insgesamt zufriedener waren als diejenigen, die in einer Outsourcing-Beziehung geblieben sind. Zudem werden verschiedene Handlungsempfehlungen für IT-Manager aufgezeigt. Zur Ausarbeitung einer zukunftsorientieren IT-Sourcing-Strategie empfiehlt es sich, eine service-spezifische Sourcing-Strategie zu verfolgen und entsprechend spezialisierte Dienstleister einzusetzen. Im Falle einer Entscheidung für ein IT-Backsourcing sollten verschiedene Erfolgsfaktoren beachtetet werden, wie z. B. eine frühzeitige Neubesetzung von Schlüsselstellen sowie ein lückenloser Wissenstransfer.

This makes it difficult for practitioners to obtain a consolidated overview of what determines CC adoption based on the numerous papers in this regard. Moreover, for further research in the field to add value, it is necessary to identify what still needs to be addressed. In this vein, we conducted a descriptive review of 39 papers, integrating the results of a previous review on 23 papers from 2014, to compare findings across studies. We identify 44 determinant factors that exhibit consistent directional influence on the dependent meta-variable “CC adoption”, extending previous literature reviews with regard to asset, client, and environmental characteristics. We then critically reviewed the research landscape to identify what is there, and what is not yet covered: Future research should specifically regard the adoption of Infrastructure-, Platform-, and Everything-as-a-Service, private, hybrid, and multi-cloud deployment, investigate vendor, solution, and individual characteristics, analyzing information systems, or the decision-maker.

Gaps Between Research and Practice in the Field of Information Systems Backsourcing T2 - 20th IEEE International Conference on Business Informatics (CBI) N2 - There is a common understanding amongst academics that information systems (IS) research sometimes has limited relevance for practitioners. This can be explained by the fact that research lags behind the fast moving IS environment, has limited practical applicability and is hard to access. We have focused on the research area of IS backsourcing, and analyzed practitioner literature to increase our understanding of topics of interest for practitioners, to determine a potential gap between academic and practitioner literature, and to identify future research directions in this field. We observed that most publications are either news or background articles, focusing on describing backsourcing cases. Additionally, we identified four recurring themes, namely reasons for backsourcing, presentation of survey results, discussion of industry trends, and backsourcing success stories. The main reasons identified to trigger backsourcing decisions are cost savings, quality improvements, and increasing control and flexibility. By comparing our findings with academic literature on IS backsourcing, we conclude that generally both literature types cover similar topics. However, researchers have a more formulative or interpretive focus than the often descriptive practitioner literature. Academic literature also examines a broader range of topics, while practitioner literature has a narrower focus. Additionally, we observe one difference regarding applied terminology: while researchers employ the term backsourcing, practitioners mostly use back in-house or insourcing. Our paper contributes to facilitating the exchange between academics and practitioners, presents topics to consider when aiming to increase practical relevance and provides researchers with concrete directions for future research within the field of IS backsourcing.

European Conference on Information Systems (ECIS 2018), Protsmouth, UK N2 - Research on Shadow IT is facing a conceptual dilemma in cases where previously “covert” systems developed by business entities (individual users, business workgroups, or business units) are integrated in the organizational IT management. These systems become visible, are therefore not “in the shadows” anymore, and subsequently do not fit to existing definitions of Shadow IT. Practice shows that some information systems share characteristics of Shadow IT, but are created openly in alignment with the IT department. This paper therefore proposes the term “Business- managed IT” to describe “overt” information systems developed or managed by business entities. We distinguish Business- managed IT from Shadow IT by illustrating case vignettes. Accordingly, our contribution is to suggest a concept and its delineation against other concepts. In this way, IS researchers interested in IT originated from or maintained by business entities can construct theories with a wider scope of application that are at the same time more specific to practical problems. In addition, value-laden terminology is complemented by a vocabulary that values potentially innovative developments by business entities more adequately. From a practical point of view, the distinction can be used to discuss the distribution of task responsibilities for information systems. KW - Business-managed IT KW - IT Governance.

The change from a productoriented to a more service-dominant business model affects the organizational structure of firms. However, literature provides limited insights into how manufacturing firms organize themselves in this transition. Even though digital technologies are critical for the transition, it is unclear how to orchestrate digital and traditional Information Technology (IT) resources in manufacturing firms accordingly. We analyze the case of a typical manufacturing firm that has adjusted its structure to reorganize for solution offerings based on product, service, and digital components. Our results describe a hybrid organizational structure that splits front- and back-end units. The back-end units are split along solution components. Digital IT resources are internalized and governed decentrally, with traditional IT resources being outsourced and steered centrally. Our findings contribute to digital servitization research by clarifying the overarching as well as the digital and traditional IT-related organization for manufacturing firms.

As a result, researchers and practitioners have created multiple concepts describing different facets and trends of this development. While the individual concepts typically focus on different aspects, there are overlaps between these concepts. This effect hampers research progress as it creates redundancies and separate streams of knowledge development. We propose a taxonomy of the concepts Lightweight IT, IT Consumerisation, Bring Your Own Device, Shadow IT, and Business-Managed IT to solve this research problem based on a systematic literature review. For this purpose, we derive characterising dimensions of each concept from existing studies and analyse literature according to the usage of terms. As a result, we can describe and delineate the concepts. Thus, we contribute a taxonomy of IT outside the IT department to improve the transfer of research results between research streams.

IT deployed or managed by business units is called Shadow IT (without alignment with the IT organization) or Business-managed IT (in alignment or a split responsibility model with the IT organization), contrasting “classical” IT. However, the responsibility for deployed IT might change over time. Therefore, this paper conceptualizes the progression of the responsibility for IT as a trajectory through initialization, potential transitions, and discontinuance. The paper illustrates this conceptual framework using four exemplary case vignettes of IT instances. Empirical findings of the case vignettes determine indications when employees initialize an IT instance as Shadow IT, Business-managed IT, or IT-managed systems and reasons why the responsibility for an IT instance changes over time. The results suggest that scholars and practitioners should add a temporal dimension to the governance of IT instances.
