TY - JOUR A1 - Kopper, Andreas A1 - Westner, Markus A1 - Strahringer, Susanne T1 - Kontrollierte Nutzung von Schatten-IT JF - HMD Praxis der Wirtschaftsinformatik N2 - Basierend auf einer systematischen und umfangreichen Analyse von Praxisbeiträgen zum Thema Schatten-IT, die zwischen September 2015 und August 2016 erschienen sind, beschreibt der vorliegende Artikel Governance-Aspekte zu diesem Phänomen. Er ergänzt damit vorhergehende akademische Studien. 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. Nach vorherrschender Ansicht entwickelt sich die IT-Abteilung als Konsequenz aus all diesen Maßnahmen zu einem nutzerorientierten, internen Service-Provider und strategischen Partner für die Fachbereiche.

Lean Management in IT-Organisationen (Lean IT) ist dahingegen in der Praxis weniger verbreitet und in der Wissenschaft kaum erforscht. Dieser Beitrag aggregiert und erweitert die Ergebnisse mehrerer Forschungsarbeiten. Dabei werden vorrangig zwei Aspekte diskutiert: (1) Ein mögliches Einführungsmodell für Lean IT. Dieses verknüpft fünf Rollen (Sponsor, Programmleiter, Navigator, Linienführungskraft und Linienexperte) mit vier Phasen (Vorbereitung, Analyse, Gestaltung und Implementierung). (2) Besondere Herausforderungen für Linienführungskräfte, die aufgrund der „bottom up“-Ausrichtung bei Lean-IT-Einführungen stark gefordert werden. Neben einer klaren Vision für die Organisationseinheit und dem Verständnis, an welcher Stelle Lean IT die Organisationseinheit konkret unterstützen kann, benötigen sie Offenheit, Veränderungswillen und die Bereitschaft Verantwortung an Mitarbeiter zu delegieren. Außerdem sollten sie über ein ausreichendes Zeitbudget für die Einführung verfügen, um ihrer gestaltenden und qualitätssichernden Funktion nachkommen zu können.

This paper presents a comprehensive view of the field of study from a managerial point of view. It provides a consolidated view of the field of study between 2010 and 2013 based on a manual search comprising 69 selected journals and 9 conferences, as well as a search using 6 journal databases. The literature review ensures continuity of research by connecting to a comprehensive literature analysis covering the years 1999 to 2009. This way it consolidates and critically reflects the state of the research of the last 14 years. Overall, we compiled 95 relevant publications originating from leading IS journals and IS conference proceedings. The results indicate that IS offshoring research is largely non-theory based, using almost entirely empirical data and interpretive research methods and -to a smaller extent -positivist research designs. The ISO research of the last 14 years focuses on the implementation stages "how" and "outcome" while the pre-implementation-stages “why”, “what”, and “which” are comparatively sparsely researched. Future studies should apply a more theory-driven approach with a greater attention on pre-implementation aspects of information systems offshoring. In addition, future research should investigate the special nature of near- and onshoring, captive offshoring as well asagile (project) management techniques suitable for ISO.

While there is much research on information systems outsourcing, the topic of backsourcing information systemsis still an emerging research area. Therefore, ourpaper aims to explore and synthesizethe existing literature on information systemsbacksourcing, since there is no exhaustiveliteraturereview of the state of the research to our knowledge available yet. In this paper, wecreate a framework to structure the existing research along the overallbacksourcing process. We identifydifferent motivators, such asexpectation gaps, orinternal and external organizational changes, leading towards a backsourcing decision, and factors positively or negatively influencing this decision. Additionally, we derive implementation success factors based on the existing literature to guide companies through the backsourcing process.We also differentiate the term backsourcing from related, sometimes synonymously used terms, by emphasizing the change of ownership back to the company of originas the main criterion.Additionally, we discuss opportunities for future research in the field of information systems backsourcing.

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.

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.

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.

This review integrates the literature on information systems and computer science to summarize managerial and technological mitigation measures that enhance cloud security. 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. Furthermore, the macro level, how stakeholders perceive cloud sourcing, is not yet well understood.

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.
