TY - JOUR A1 - Strasser, Artur A1 - Westner, Markus A1 - Strahringer, Susanne T1 - Knowledge transfer in IS offshoring BT - A Delphi study of the offshore coordinator role JF - Journal of Systems and Information Technology N2 - Purpose This paper aims to investigate the main tasks, necessary skills, and the implementation of the offshore coordinator’s role to facilitate knowledge transfer in information systems (IS) offshoring. Design/methodology/approach This empirical exploratory study uses the classical Delphi method that includes one qualitative and two quantitative rounds to collect data on IS experts’ perceptions to seek a consensus among them. Findings The participants agreed, with strong consensus, for a set of 16 tasks and 15 skills. The tasks focused primarily on relationship management and facilitating knowledge transfer on different levels. The set of skills consists of approximately 25 per cent “hard” skills, e.g. professional language skills and project management skills, and approximately 75 per cent “soft” skills, e.g. interpersonal and communication skills and the ability to deal with conflict. Two factors mainly influence implementing the offshore coordinator role: project size and the number of projects to be supported simultaneously. Practical implications The findings provide indications of how to define and fulfill this crucial role in practice to facilitate the knowledge transfer process in a positive way. Originality/value Similarities in previous research findings are aggregated to examine the intermediate role in detail from a consolidated perspective. This results in the first comprehensive set of critical tasks and skills assigned to the competency dimensions of the universal competency framework, demonstrating which and how many competency dimensions are critical.

To address this challenge, some IT organizations have adopted Lean Management (LM). Although LM is a standard production mode in manufacturing, it is less familiar to IT organizations. The purpose of this paper is to identify 12 lessons learned from companies who implemented LM in their IT organization (Lean IT) to free up their IT resource capacity from existing day-to-day operations so they could use it to enable their digitization strategy. Design/methodology/approach A case study of two major international companies from different industries. Data were collected from 25 structured interviews. Findings The lessons learned provide insights into how these companies implemented Lean IT, the potential outcomes they aimed for, what they did to achieve those outcomes, how they facilitated the implementation of Lean IT, and restrictions they encountered during the implementation. Research limitations/implications The findings are based on a limited range of IT organizations. Practical implications The lessons learned inform those implementing Lean IT because they explain how companies have implemented Lean IT to facilitate digitization and the benefits and pitfalls they encountered. A comparison of Lean IT and Lean Production shows that LM is transferable to IT organizations if domain specific requirements are respected. Originality/value This paper reports the unique experience of companies implementing Lean IT, which can inform other companies in a similar situation.

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.

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.

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.

However, we lack research that focuses on the success of lean management implementations in IT organizations (lean IT). This paper contributes to knowledge of the success factors of lean IT implementation and the relative importance of each factor based on the insights of field experts. The experts identified, agreed on, and ranked 12 implementation success factors for lean IT in a Delphi study using the best/worst scaling technique. The most important factors were leadership involvement, change culture and work ethic, employee involvement, and performance management. Factors of intermediate importance were implementation facilitation, training and education, clear vision and direction, long-term focus, communication, and a holistic approach. Least important factors were existing skills, organizational changes/standardization, and financial resources. This paper contributes a more nuanced understanding of the relative importance of lean IT success factors, proposes relationships between them, and comprehensively explains how to use the rigorous best/worst scaling method in a traditional ranking-type Delphi study.

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.

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.

The study at hand investigates the implementation of Lean Management to IT organizations (Lean IT). The study offers three contributions: First, it explains on a conceptual level how Lean Management can be transferred from production to IT organizations (philosophy, principles, tools). Second, it provides a theoretical perspective on why Lean IT can be beneficial for IT organizations (IT Slack theory). Third, it provides insights to the stated research questions (three benefits and three propositions) from an initial case study of an internal IT service provider for a large international insurance company (> US$25 Billion revenue; >20,000 employees; active in >120 countries) and lays out the research methodology and potential focus areas for further studies.

This variety makes it difficult to identify related research and build upon it. 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.

März 2016 N2 - Shadow IT is a widespread phenomenon which includes systems, services, and processes that are not part of the "official" corporate IT. 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.
