TY - JOUR A1 - Kobus, Jörn A1 - Westner, Markus A1 - Strahringer, Susanne T1 - Change management lessons learned for Lean IT implementations JF - International Journal of Information Systems and Project Management N2 - Lean Management is a standard production mode that has been familiar to production organizations for several decades. To date, however, academic literature has presented surprisingly little information about the application of Lean Management in Information Technology (IT) organizations, or what is called Lean IT. Drawing upon an empirical qualitative case study of the IT departments of two multinational companies, in this paper we identify change management lessons learned for Lean IT implementations, as well as seven characteristics of a corresponding change management approach. As an extension of our work, researchers should validate and expand our initial findings, preferably in a quantitative setting.

While implementations of ITO around the world share some common characteristics like typical reasons for outsourcing, key success factors, or dimensions along which they can be classified, extant research also points to regional differences. However, research on this topic, specifically regarding pivotal contract features like contract value, contract length, or pricing methods, is still in its infancy, and quantitative analyses on the subject are particularly scarce. We address this research gap by analyzing data on 14,917 ITO contracts closed between 2007 and 2017 through the lens of cultural regions and three statistical methods. The contribution of our paper is threefold. First, our descriptive analysis points to globally decreasing contract lengths and contract values, confirming previous studies and practice reports. Second, an ANOVA with independent post-hoc testing provides quantitative supportfor the degree of dissimilarity among individual regions in pivotal ITO contract features. Finally, our quantitative replication of a previous study identifies culture-induced regional differences between USA and Japan regarding the effect of influence factors on ITO contract features.

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.

These frameworks are more frequently being used in practice in large-scale system development activities. Therefore, they are in the scope of project portfolio management. The paper examines the conformity of selected scaling agile frameworks to the objectives of project portfolio management through qualitative analysis. Four prominent frameworks are investigated: Scrum of Scrums, Large cale Scrum, Disciplined Agile, and the Scaled Agile Framework. The study shows significant differences between the frameworks and their view on project portfolio management with the Scaled Agile Framework offering the most detailed portfolio management-relevant processes and roles. In contrast to that, Large Scale Scrum does not see the need for portfolio management but promotes self-managing teams. Two of the four frameworks share the perception shift from projects to the products, which has significant implications for practitioners because it challenges and redefines prevalent management roles and practices.

However, studies worldwide indicate that a large number of companies that engaged in IS offshoring are not satisfied with the outcome. Our study examined the determinants of IS offshore project success: We developed a model and empirically tested it with data collected from 304 experts who reported on projects offshored from Germany to a wide range of near and distant countries. The model posited a direct effect of offshoring expertise and trust in offshore service provider (OSP) on success, as well as an indirect effect mediated by project suitability, knowledge transfer, and liaison quality. An analysis using partial least squares (PLSs) provided significant support for almost all these relationships. However, it showed that offshoring expertise played a minor role in explaining success and the mediating constructs. Trust in OSP had a small direct effect on success and a medium to large effect on the mediating constructs. Project suitability, knowledge transfer, and liaison quality all had small direct effects on success.

The Blockchain technology is claimed to revolutionize how business is being conducted by its way of storing data and sharing it with others. The recently introduced GDPR has a huge impact on processing personal data because it brought major changes to privacy regulation. This might also affect the processing of personal data in Blockchain-based application scenarios. Based on literature analysis, the paper at hand provides an overview of the Blockchain technology, presents a decision model, and introduces two possible Blockchain application scenarios. It analyses relevant requirements of the GDPR in view of processing personal data and compares these with the fundamental principles of the Blockchain technology. The paper concludes that processing personal data in the Blockchain is violating the GDPR because it conflicts with fundamental specification of this regulation. This finding reveals the need for further research to propose concepts and frameworks for a GDPR-compliant processing of personal data using Blockchain technology.

Relying on a sample of 304 projects conducted at various industry sectors and companies, results show that IS offshoring primarily occurs in sectors Telecommunications and IT at large corporations. Cost reduction is the main reason for going offshore and offshore projects are executed as part of a larger program at companies. Noticeably, most projects are delivered from India. Additionally, neither captive offshoring nor offshore outsourcing dominates as a de-livery option. Comparing different project subgroups regarding project success, the results reveal that projects delivered by an internal or partially owned service provider are more successful. Other project characteristics such as a project’s embedded-ness in a larger offshoring program, a project’s size, or a project’s offshoring degree in terms of relatively offshored labor hours show few significant differences. The paper addresses the paucity of empirical research on the current state of the IS offshoring phenomenon in Germany.

This paper examines evaluation criteria and their importance for selecting application or project candidates for offshoring. Based on a literature analysis and interviews with 47 experts from 36 different German companies describing 64 case examples, we find that in contrast to the literature, “size”, “codification”, and “language” are perceived as important selection criteria by experts. Case examples additionally show that “business specificity” seems to be a main reason for application or project failures, that “business criticality” appears to be less important than suggested by the literature, and that adequate “size” might be a necessary prerequisite, but seems not to be a sufficient criterion for an application’s or project’s suitability for offshoring. These differences in comparison to findings from the literature may be explained by cultural and language differences.

The analysis uncovers gaps regarding the empirical investigation of security considerations in the corporate decision-making process. Specifically, the micro level of how security comes into play in the decision-making process and whether mitigation measures proposed by scholars are practically feasible requires further investigation.

This paper investigates the experiences of students undertaking their internship capstone in other countries under the supervision of a partner institute and a participating industry sponsor. These experiences of German students interning in New Zealand (NZ), and NZ students interning in Germany offer an insight into the organisation required by the partner institutions and the comparative cultural and technical differences that these students have encountered. The international agreement between Ostbayerische Technische Hochschule (OTH) Regensburg, Germany, and the Eastern Institute of Technology (EIT), NZ, has already built a mutual framework of visiting lecturers teaching in each other's institutes, and a programme of hosting exchange students in each other's institutes. A natural progression of this partnership has now moved into the active recruitment and brokering of international internship opportunities for their respective final year Business and Information Technology (IT) students. The benefits are evident personally to the students, which are discussed in this paper, but there are also clear benefits for EIT and OTH in terms of marketing opportunities for prospective students and enriching the learning environments. This paper explores the challenges faced by the Schools of Business and Computing at EIT as it pioneers the first two years of establishing internship options for final year German exchange students within NZ, and matching final year EIT degree students to industry sponsors within Bavaria, a federal state of Germany. A qualitative approach was taken for this study with data acquired from internship students involved, the key organising lecturers from each institute, and industry sponsors from each country. A number of student, staff and industry representative interviews were conducted along with a cultural appraisal of relevant literature in the global education field. A further overview of the macro benefits for the partner institutes in terms of marketing, and programme enrichment is also part of the conclusion. The paper may be useful as a template for other institutes on developing international internship opportunities through global partners.

BT - Gaps between research and practice in the field of information systems backsourcing T2 - Proceedings of the 20th IEEE International Conference on Business Informatics (IEEE CBI 2018): Vienna, Austria, 11-14 July 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.

März 2018 N2 - Information technology outsourcing (ITO) has long been recognized for its numerous potential advantages such as lowering costs, accessing external skills, and improving efficiency, flexibility, and quality. However, it also exposes client companies to various risks, including vendor lock-in, poor agility, or insufficient vendor expertisein individual domains, especially inincreasingly dynamic market environments. Consequently, companies increasingly implement multisourcing by composing a “best of breed” set of vendors for their various IT services. In this paper,we use a dataset of 1,016 ITO deals closed with Austrian, Swiss, and German client companies between 2006 and 2017 to analyze the development of the ITO market in general and multisourcing in particular. Our results show decreasing services run rates, shorter contract lengths, an increasing number of concurrent service providers per client,and a distribution of the total number of contracts to a larger set of vendors, all pointing towards an increasing popularity of multisourcing.

However, besides several studies investigating a rigorous application of ranking-type Delphi as a research method, a comprehensive and precise step-by-step guide on how to conduct a rigorous ranking-type Delphi study in IS research is currently missing. In addition, a common critic of Delphi studies in general is that it is unclear if there is indeed authentic consensus of the panelists, or if panelists only agree because of other reasons (e.g. acquiescence bias or tiredness to disagreement after several rounds). This also applies to ranking-type Delphi studies. Therefore, this study aims to (1) Provide a rigorous step-by-step guide to conduct ranking-type Delphi studies through synthesizing results of existing research and (2) Offer an analytical extension to the ranking-type Delphi method by introducing Best/Worst Scaling, which originated in Marketing and Consumer Behavior research. A guiding example is introduced to increase comprehensibility of the proposals. Future research needs to validate the step-by-step guide in an empirical setting as well as test the suitability of Best/Worst Scaling within described research contexts.

This paper discusses the planning of a joint course to be delivered online and face to face by two lecturers representing two tertiary institutes in Germany and New Zealand respectively. The IS offshoring content of the course is relatively unique and aspects of globalisation will be demonstrated through the dual country delivery of the course. The two lecturers involved have spent time lecturing and studying in their global partner’s country and tertiary institutes and so this joint delivery method is likely to also strengthen cultural ties between the two participating institutions including the students involved. Further research goals and issues are discussed for post-delivery of this dual country blended course. This paper provides a basis for this concept to be evaluated in further research.

To address this ambiguity, we reduce the different terms to six distinct concepts by developing a taxonomy and examining their relation¬ships. We do so by using a rigorous iterative methodology to identify common characteristics and to classify terms along them. By clustering the results, we derive and visualize the taxonomy. The identified concepts are Feral Practices, Workarounds, Shadow IT, Shadow Systems, Un-enacted Projects, and Shadow Sourcing. We elaborate on the concepts along their characteristics and clearly define and delimit them. As a result, we create a guide for their usage, increase search- and comparability, and unify existing knowledge.

The topic is still an emerging research area and slowly gaining traction in recent years but a state of the art analysis is missing to date. We therefore conduct a structured literature review to derive a framework for causes, consequences, and governance of Shadow IT. We identify motivators, enablers, and missing barriers as causes for Shadow IT, both positive and negative consequences on an organizational and a technical level and governance approaches which focus on clearance of existing or prevention of future Shadow IT. Our review reveals that constructivist, qualitative design using a case study approach dominates existing research. There are no dominant theories yet to explain Shadow IT. We also highlight possibilities for future research to focus on the less explored governance aspect.

While most data centers run on a virtualized environment, Cloud Computing technology emerges with new characteristics on fast provision of standardized resources in a scalable IT infrastructure. Public cloud vendors offer IT services on demand, so that IT organizations do not have to operate their own hardware. Moreover, private cloud architectures gain influence, claiming to provide flexible and elastic IT infrastructure. The paper at hand guides the strategic decision for adoption of Cloud Computing on IT infrastructure. Therefore, we first introduce a taxonomy for IT infrastructure encompassing a technological and a sourcing perspective. Second, we evaluate selective areas of the taxonomy adopting the SWOT framework to understand both opportunities and challenges of Cloud Computing for IT infrastructure from a business perspective.

For example, companies from various industries are focusing their efforts to digitize business models, to adopt agile forms of collaboration, and to leverage automation of routine tasks. This forces companies to review their IS sourcing strategies and to potentially consider alternatives for current outsourcing contracts. One potential option could be to backsource IS services currently performed by external vendors. Based on empirical observations, previous academics defined it as the repatriation of all assets, activities, and skills needed to perform IS services back in-house, which had been outsourced previously to one or multiple vendors. The distinctive characteristic of backsourcing is the change in ownership back to the mother organization. This distinguishes the term backsourcing from similar terms, e.g., backshoring, reshoring, or relocating, which rather focus on the change in location of the service delivery. At the initial sourcing decision, the strategy to outsource an IS service was considered most promising. However, certain developments both inside the company, but also on a broader industry level may lead to a re-evaluation of the situation and thus to an adjustment of the original sourcing strategy. Over the last years, there has been a strong increase in cloud-based services and a shift towards the deployment of standardized, almost “industrialized” applications as services. Before, large companies leveraged their size in realizing economies of scale within their sourcing volumes. The raise of cloud computing as well as standardization of service delivery decreased those benefits and led towards a decline in large outsourcing contracts across a variety of services and a growth of multi-sourcing of individual IS services from the respective “best-in-breed” vendors for shorter time periods. Besides sourcing the best vendor for each service, companies that implement multi-sourcing strategies additionally aim for cost benefits due to an increased competition between vendors, and an increase in agility and adaptability. At the same time, a move towards multi-sourcing strategies with shorter contract durations leads to an increase in so-called “second generation sourcing decisions”, namely whether to continue outsourcing a respective service or to bring the service back in-house. Given the developments within the IS environment, this research projects aims at understanding why IS services are backsourced and which factors influence a company’s decision to backsource an IS service.

Those courses and their videos are often professionally produced and incorporate a significant investment of time and financial resources. In many cases such courses are “flagship” productions of the associated school or university and produced with budgets lecturers in other institutions do not have available. This makes the use of videos in a regular teaching environment challenging. In addition, lecturers often act in high-teaching-load environments further tightening their capacity constraints. This raises the question whether and how lecturers can benefit from videos in their lectures for increased teaching effectiveness while not sacrificing teaching efficiency. The paper at hand attempts to address this question by providing a critical perspective on the use of videos in a high-teaching-load environment characterized by little financial and staff resource availability. The paper thereby builds upon the three years’ experience of its author in using videos to enhance lectures in German tertiary education institutions in a multi-language, i.e., English and German, teaching environment. The presented findings are both relevant for teaching practice and research: lecturers may benefit from the presented ideas and experiences and may adopt them for their teaching. Researchers may find starting points for new research opportunities on the effectiveness and efficiency of video-enhanced lecturing and learning. The paper is organized as follows. Section 2 describes the context of the study from an institutional and technological perspective. Section 3 outlines the methodology applied and 4 how data was collected. Results from data analysis are presented in section 5. The paper concludes with a reflective summary and outlook in section 6.

Consequently, companies expect that graduates have intercultural skills and that they are able to work in globally distributed teams, especially in professional services like consulting or in IS. However, management or IS curriculums often lack courses that teach those respective skills. The suggested course attempts to fill this gap through an innovative course design and delivery. The course intends to replicate a professional project environment in which the students are supposed to deliver a project as a joint international team. In the beginning of the course, students learn key aspects of project management, intercultural management, distributed collaboration, and the professional services industry in a self-paced manner through video lectures. Then they form teams, plan their project, and subsequently execute their project plan jointly. Instructors from the participating institutions supervise and coach the students. The project execution is supposed to resemble a business project with a meeting schedule, agreed deliverables, regular steering committees in which the instructors play the role of the clients. This paper outlines the concept of this international blended-teaching course. It suggests potential learning objectives, a course description, a teaching syllabus, and an assessment framework.

Recently, the interest to investigate a wider application of Lean Management especially in service functions increased. However, it is not clear how Lean Management can be applied to IT organizations. Therefore, this study aims to provide an overview on common characteristics and future research directions. A literature review on existing scholarly research from January 2004 to June 2014 is conducted. Using a database-driven search approach, a total of 1,206 research contributions are found of which 49 were identified as relevant. Results indicate a low theory grounding of mostly formulative and interpretative research items. This implies that research on Lean Management of IT organizations is still at its nascent state. Content-wise, five research themes emerge. The majority of research investigates IT organizations in a role to support Lean Management in production/manufacturing functions (determining “what to work on”), therefore more research on how Lean Management can be applied to IT organizations themselves (determining “how to work”) could be beneficial. Future research could also try to build on Change Management theories, as the implementation of Lean Management is of transformational character.

Recently, the interest to investigate Lean Management also in service functions increased. Therefore, this study aims to (1) Consolidate critical success factors (CSFs) for the implementation of Lean Management of IT organizations; and (2) Describe a theoretical foundation for these CSFs. With respect to (1) a database-driven search was conducted. CSFs then were extracted and categorized. In total 13 CSF groups were assigned to three dimensions: Mindset and behavior; Organization and skills; and Process facilitation and performance management. To understand underlying mechanisms better, and with respect to (2) we related existing (IS) theory to identified groups of CSFs. Especially, five theoretical concepts are discussed: Absorptive capacity, Agency theory, Cognitive dissonance, Dynamic capabilities, and System dynamics. Future research needs to validate the results of (1) and (2) empirically in IT functions.

Markus Westner examines the IS offshoring phenomenon from the perspective of German companies. He first provides an overview of the current literature in the field of IS offshoring. Based on interviews with 47 industry experts, evaluation criteria for selecting projects for offshoring are identified. Finally, the author examines determinants of IS offshore project success in German companies based on a statistical analysis of 304 projects using structural equation modeling (PLS).

Methods and tools for risk management. Karlsruhe: Universitätsverlag Karlsruhe N2 - This paper empirically examines the current state of the IS offshoring phenomenon in Germany regarding project characteristics and success patterns. Relying on a sample of 304 projects conducted at various industry sectors and companies, results show that IS offshoring primarily occurs in sectors Telecommunications and IT at large corporations. Cost reduction is the main reason for going offshore and offshore projects are executed as part of a larger program at companies. Noticeably, most projects are delivered from India. Additionally, neither captive offshoring nor offshore outsourcing dominates as a de-livery option. Comparing different project subgroups regarding project success, the results reveal that projects delivered by an internal or partially owned service provider are more successful. Other project characteristics such as a project’s embedded-ness in a larger offshoring program, a project’s size, or a project’s offshoring degree in terms of relatively offshored labor hours show few significant differences. The paper addresses the paucity of empirical research on the current state of the IS offshoring phenomenon in Germany.

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.

Additionally, there are also overt forms in practice, so-called Business-managed IT, which share most of the characteristics of Shadow IT. To better understand this phenomenon, we interviewed 29 executive IT managers about positive and negative cases of Shadow IT and Business-managed IT. By applying qualitative comparative analysis (QCA), we derived four conditions that characterize these cases: Aligned, local, simple, and volatile. The results show that there are three sufficient configurations of conditions that lead to a positive outcome; one of them even encompasses Shadow IT. The most important solution indicates that IT systems managed by business entities are viewed as being positive if they are aligned with the IT department and limited to local requirements. This allows to balance local responsiveness to changing requirements and global standardization. In contrast, IT systems that are not aligned and permanent (and either organization-wide or simple) are consistently considered as negative. Our study is the first empirical quantitative–qualitative study to shed light on the success and failure of Shadow IT and Business-managed IT.

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.

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.

Nevertheless, some CIOs have been successful in their position for a long time. In this study, we use tenure as a proxy for success as a CIO. 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.

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.

Through an inductive text analysis of sixteen literature reviews spanning from 2014 to 2023, key themes and concepts are identified, highlighting the complex relationship between ICT and sustainability. 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. The paper summarizes and discusses the developments in research on this topic over the past decade.

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.

Es zeigt sich, dass unter Praktikern der Eindruck vorherrscht, dass IT-Abteilungen unter zunehmendem Druck stehen, schneller auf sich ändernde Anforderungen aus den Fachbereichen reagieren zu müssen. Können IT-Abteilungen diesen Erwartungen nicht entsprechen, beschaffen sich Fachbereiche und Nutzer selbst Lösungen in Form von Schatten-IT. Als mögliche Antwort darauf kann sich die IT-Abteilung agiler organisieren und die IT-Architektur im Unternehmen modernisieren. Eine weitere Möglichkeit besteht darin, sich das innovative Potenzial von Schatten-IT zunutze zu machen und deren Umsetzung aktiv durch organisatorische und technische Maßnahmen zu unterstützen. IT-Sicherheitsmanagement und technische Schutzmechanismen können helfen, die so entstandenen Lösungen abzusichern und die Risiken zu minimieren. Die IT-Abteilung könnte sich als Konsequenz aus all diesen Maßnahmen zu einem nutzerorientierten, internen Service-Provider und strategischen Partner für die Fachbereiche entwickeln.

Die vorliegende Arbeit schließt diese Forschungslücke und präsentiert eine umfassende Literaturübersicht über das CIO-Forschungsfeld unter Verwendung der Hauptpfadanalyse. Anhand einer quantitativen und qualitativen Analyse von 438 Forschungsbeiträgen werden die zentralen Arbeiten in der CIO-Forschung und verschiedene Forschungsrichtungen identifiziert. Es zeigt sich, dass sowohl etablierte Forschungsrichtungen, wie z. B. ‚Entwicklung der CIO-Rolle‘ und ‚Hierarchische Position und Beziehungen des CIOs‘, als auch neu entstehende Forschungsrichtungen, wie z. B. ‚CIO als Business Enabler‘, wachsende Aufmerksamkeit auf sich ziehen. Auf der Grundlage der Ergebnisse werden vielversprechende weitere Wege auf dem Gebiet der CIO-Forschung aufgezeigt, z. B. solche, die den Einfluss neuerer Technologien untersuchen. N2 - Despite the relevance and maturity of research related to the Chief Information Officer (CIO) role, there are few studies that objectively and comprehensively summarize the current state of the art. This paper fills this research gap and presents a comprehensive literature review of the CIO research field using main path analysis. Based on a quantitative and qualitative analysis of 438 research articles, the central contributions in CIO research and different research directions are identified. Our results show that both established research directions, such as ‘CIO Role Development’ and ‘CIO Hierarchical Position and Relationships’, and emerging research directions, such as ‘CIO as Business Enabler’, are attracting growing attention. Based on the results, we derive promising further directions in the field of CIO research, e.g., such as those investigating the impact of new technologies.

Researchers value configurational methods like Qualitative Comparative Analysis (QCA) as their application contributes to a better understanding of complex phenomena. QCA helps to uncover interrelations of conditions that lead to an outcome, building on the principles of equifinality, conjunctural causation, and asymmetry. More recently, IS researchers have started to analyze qualitative data, like case study data, with QCA. However, there is a lack of methodological guidance on how to calibrate qualitative data into set membership values for QCA. Therefore, this paper structures methodological steps and the associated options to calibrate qualitative data from an interdisciplinary perspective and critically reviews the observed methodological choices in IS research. This paper also gives recommendations for calibrating qualitative data to support informed methodological choices for future research.

The framework design is based on analysis and integration of literature combined with empirical findings. The framework was evaluated by CIO interviews and a practical feasibility study. The results show that IT business value can be measured and communicated using our framework by applying six consecutive process steps. Thereby, IT business value is not a single number but a set of quantitative and qualitative metrics relevant to stakeholders. Our framework represents a novel and integrated approach on how CIOs can select appropriate metrics, measure, and communicate IT business value to stakeholders. In addition, the paper provides insights for CIOs on how to be successful in IT business value management.
