DESIGN/METHODOLOGY/APPROACH This paper builds upon extant literature on culture on the national, organizational and team level, conceptualizes its effect on relationship quality and ITO success, and hypothesizes a model on potential moderators and management techniques to offset culture-induced challenges. It then evaluates and refines the model by means of an interpretive qualitative research design for an in-depth single-case study of ProSiebenSat.1 Media SE (P7S1), a leading European media company that reconfigured its IT sourcing model three times in 10 years.

We conducted semi-structured interviews and a Delphi study with seventeen experts to address these gaps. As a result, we identified twelve drivers and nineteen inhibitors for adopting LCDPs. We show that the experts have a consensus on the most and the least important drivers and inhibitors for LCDP adoption.

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.

We observed that most publications are either news or background articles, focusing on describing backsourcing cases.

The main reasons identified to trigger backsourcing decisions are cost savings, quality improvements, and increasing control and flexibility.

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.

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.}, subject = {Betriebliches Informationssystem}, language = {de} } @inproceedings{Westner, author = {Westner, Markus}, title = {Video-enhanced lectures in high-teaching-load environments with limited resources}, series = {Proceddings of the 11th International Technology, Education and Development Conference (INTED 2017), Valencia, Spain. 6-8 March}, booktitle = {Proceddings of the 11th International Technology, Education and Development Conference (INTED 2017), Valencia, Spain. 6-8 March}, doi = {10.21125/inted.2017.0168}, pages = {197 -- 207}, abstract = {Massive Open Online Courses (MOOCs) have been gaining a lot of attention in the last years.

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.

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.}, subject = {Integriertes Lernen}, language = {en} } @inproceedings{KobusWestner, author = {Kobus, J{\"o}rn and Westner, Markus}, title = {Lean Management of IT Organizations}, series = {Proceedings of the 19th Pacific Asia Conference in Information Systems (PACIS 2015), Singapore, Jul 5-9}, booktitle = {Proceedings of the 19th Pacific Asia Conference in Information Systems (PACIS 2015), Singapore, Jul 5-9}, pages = {16}, abstract = {Lean Management has been successfully applied by companies around the world, mainly in production/manufacturing functions.

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 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.

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.}, subject = {Informationsmanagement}, language = {en} }
