In this context, the paper revisits the concept of IT capabilities. We summarize the "canonical" body of literature to characterize how leading scholars conceptualized and differentiated IT capabilities and then we show how new types of IT capabilities (for example, rising from SMACIT technologies) relate to this. We find that the resource-based view is still leading in how to conceptualize IT capabilities. However, an alternative perspective on IT assets is emerging, looking at it from the angle of digital technologies as stacks. Digital technologies form the foundation for a new technology-driven perspective on IT capabilities. This new view complements the established differentiation of IT capabilities considering IT infrastructure flexibility, IT management, and IT personnel capability. Both perspectives describe the explorative and exploitative nature of IT capabilities. This paper helps scholars and practitioners to clearly distinguish different perspectives of IT capabilities on how to build a competitive advantage from IT today.}, subject = {Informationstechnik}, language = {en} } @article{HillebrandWestner, author = {Hillebrand, Patrick and Westner, Markus}, title = {Success factors of long-term CIOs}, series = {Information Systems and e-Business Management}, volume = {20}, journal = {Information Systems and e-Business Management}, publisher = {Springer Nature}, doi = {10.1007/s10257-021-00546-z}, pages = {79 -- 122}, abstract = {Although the average tenure of CIOs has increased over the last years, the majority of CIOs have been in their positions for only three years or less.

The goal of this paper is to examine factors that are critical to the success of long-term CIOs. For this purpose, we created and analyzed resumes of 384 CIOs. Out of these 384, we conducted 19 interviews with CIOs from top-tier companies and collected and analyzed both qualitative and quantitative data. In the process, we were able to identify nine factors that are critical for the success (CSF) of CIOs. These factors fall into three categories. Category "Personality" includes "Accepting and embracing change" (CSF \#1), "Being perseverant to pursue long-term goals" (CSF \#2), "Anticipating the future through visionary thinking" (CSF \#3), and "Being empathetic to deal with uncertainty felt by co-workers" (CSF \#4). The "Role Fulfilment" category includes "Cross-functional involvement and integration of the IT organization" (CSF \#5), "Positioning and restructuring of the IT organization" (CSF \#6), and "Well-connected and communicative leadership" (CSF \#7). The "Organizational Environment" category consists of "Availability of skilled workforce" (CSF \#8) and "Reporting line to the CEO" (CSF \#9). CSFs 1, 2, and 3 were perceived as most important by the participating CIOs. The results may be of particular interest both to aspiring CIOs and equally their employing organizations, as they reflect what long-term CIOs value during their time in office.}, language = {en} } @article{WulfWestnerStrahringer, author = {Wulf, Frederik and Westner, Markus and Strahringer, Susanne}, title = {Cloud Computing Adoption: A Literature Review on What Is New and What We Still Need to Address}, series = {Communications of the Association for Information Systems}, volume = {48}, journal = {Communications of the Association for Information Systems}, number = {1}, publisher = {Association for Information Systems, AIS}, issn = {1529-3181}, doi = {10.17705/1CAIS.04843}, pages = {523 -- 561}, abstract = {Research on cloud computing (CC) recently emerged congruently with the technology's importance for organizations at a fast pace.

ICT is perceived both as an enabler and a problem for sustainability. Furthermore, the terminology and concept of sustainability in the context of ICT remain unclear. The emergence of digitalization as a novel socio-technical phenomenon poses additional challenges for conceptual alignment. While a holistic view of sustainability in ICT is desired, business and social implications receive less attention.

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.}, language = {en} } @inproceedings{KopperFurstenauZimmermannetal., author = {Kopper, Andreas and Furstenau, Daniel and Zimmermann, Stephan and Rentrop, Christopher and Rothe, Hannes and Strahringer, Susanne and Westner, Markus}, title = {Business-managed IT: A conceptual framework and empirical illustration}, series = {26.

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.}, language = {en} } @article{WestnerKratzerDrechsleretal., author = {Westner, Markus and Kratzer, Simon and Drechsler, Andreas and Strahringer, Susanne}, title = {The Fractional CIO in SMEs: conceptualization and research agenda}, series = {Information Systems and e-Business Management}, volume = {20}, journal = {Information Systems and e-Business Management}, publisher = {Springer}, doi = {10.1007/s10257-022-00557-4}, pages = {581 -- 611}, abstract = {We conceptualize the new phenomenon of the Fractional Chief InformationOfficer (CIO) as a part-time executive who usually works for more than one pri-marily small- to medium-sized enterprise (SME) and develop promising avenuesfor future research on Fractional CIOs.

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.
