T2 - Consumer Health Informatics N2 - Medical confidentiality is very important because it builds the fundament of trust between doctors and patients. In modern health services data protection is essential. But there are also other important security objectives, such as integrity and authenticity of medical data and health services, as their breach can potentially lead to life threatening conditions. State of the art security mechanisms are necessary to protect medical data and services and prevent attacks known as “hacking”. They should include in particular cryptography, as you can usually rely on mathematics, more than in software security and access control mechanisms. As patients normally cannot assess the security of a service, security audits or certifications of health services should be provided to generate trust and confidence.

For the first time, this year’s challenge was organized as a cooperation between Technische Universität Dresden, GlobalFoundries, and ScaDS.AI Dresden/Leipzig. The Challenge’s participants were given real-world production and energy data from the semiconductor manufacturer GlobalFoundries and had to solve the problem of predicting the energy consumption for production equipment. The usage of real-world data gave the participants a hands-on experience of challenges in Big Data integration and analysis. After a leaderboard-based preselection round, the accepted participants presented their approach to an expert jury and audience in a hybrid format. In this article, we give an overview of the main points of the Data Science Challenge, like organization and problem description. Additionally, the winning team presents its solution.

The study focused on one of the most challenging parts in this domain: the generation of an object model for a software product based on a requirements specification. During their training, software engineers are taught different techniques to solve this task. One of these techniques is the noun/verb analysis. However, it is still unclear to what extent novice and expert programmers are making use of it. Ideally, the noun/verb analysis works as a heuristic and helps programmers to make fast and accurate decisions. Participants in the study were 40 software programmers at four levels of expertise (novices, intermediates, experienced rogrammers, experts). They were presented with ten decision tasks. In each task, participants read a requirement specification and then had to choose one out of three presented class diagrams that they considered the best solution. During the task, their eye movements were recorded. Results show that all participants used the noun/verb analysis as a heuristic. Programmers with higher levels of expertise, however, outperformed programmers with lower levels of expertise. Interestingly, the more experienced programmers were not following the noun/verb analysis in a blindfolded way. They realised that the noun/verb analysis would produce diagrams, but a skilled software architect would not model them in this way. Instead they created their models in a way that they perceived as more logical and realistic Y1 - 2019 UR - https://earli.org/sites/default/files/2019-09/BOA-2019.pdf PB - RWTH Aachen ER - TY - CHAP A1 - Soska, Alexander A1 - Schumm, Michael A1 - Joseph, Saskia A1 - Reschke, Michael A1 - Mottok, Jürgen A1 - Niemetz, Michael A1 - Schroll-Decker, Irmgard T1 - Comparison of Frontal Lecture and Workshop Learning Arrangements in a Software Engineering Education Project T2 - 2014 IEEE Global Engineering Education Conference (EDUCON), Istanbul, Turkey N2 - The increase in complexity of software and its creation over the last decades requires an increase in the quality of the education of software engineering professionals. The number of Universities which answer this call by replacing or extending lectures with simulated software projects is constantly rising. However, the question how to best transfer new technological knowledge needed to be successful within this projects to the students remains open. Therefore this paper will present a comparison between the classical frontal lecture and a modern workshop learning arrangement used within these projects. By the use of workshops not only the knowledge transfer but also the acquisition of personal and social competences will be facilitated. Furthermore positive experiences with workshops at university level will support life-long learning.

We present a novel method for tracking this otherwise invisible evolution of software changes on mailing lists by connecting all early revisions of changes to their final version in repositories. Since artefact modifications on mailing lists are communicated by updates to fragments (i.e., patches) only, identifying semantically similar changes is a non-trivial task that our approach solves in a language-independent way. We evaluate our method on high-profile open source software (OSS) projects like the Linux kernel, and validate its high accuracy using an elaborately created ground truth. Our approach can be used to quantify properties of OSS development processes, which is an essential requirement for using OSS in reliable or safety-critical industrial products, where certifiability and conformance to processes are crucial. The high accuracy of our technique allows, to the best of our knowledge, for the first time to quantitatively determine if an open development process effectively aligns with given formal process requirements.

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.

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 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.

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.

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.

A1 - Furlong, A. T1 - Global student collaboration through international blended learning T2 - Proceedings of the 10th Annual International Conference of Education, Research and Innovation (ICERI2017), Seville, Spain. 16-18 November N2 - In today’s business, collaboration in globally distributed teams becomes more and more common. This is particularly the case in professional services and information systems (IS) where the immaterial nature of services makes globally distributed service creation easily possible. 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.
