Against this background, this paper analyzes the complex nature of cultural distance and its multi-faceted effect on ITO success. 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. FINDINGS The results from interviews with top managers from client and provider organizations represent one of the first integrated views on the critical importance of cultural compatibility on multiple levels, provide manifold examples for its complex effect on ITO success, as well as moderators and potential management techniques to promote ITO success. RESEARCH LIMITATIONS/IMPLICATIONS This paper contributes relevant empirical insights to the growing body of literature on culture and its underestimated role in ITO success. It builds on tentative theory that is confirmed and refined. PRACTICAL IMPLICATIONS The paper helps in substantiating the complex and intangible nature of culture and demonstrates means for its effective management.

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. Yet, the ranking of the drivers and inhibitors between the most and least important is highly context dependent. For some drivers and inhibitors, the experts' ranking is similar to academic literature, whereas, for others, it differs.

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} } @article{StrahringerWestnerKobus, author = {Strahringer, Susanne and Westner, Markus and Kobus, J{\"o}rn}, title = {Lean IT}, series = {WISU - Das Wirtschaftsstudium}, journal = {WISU - Das Wirtschaftsstudium}, number = {1}, pages = {87 -- 92}, subject = {Informationstechnik}, language = {de} } @inproceedings{WestnerStrahringer, author = {Westner, Markus and Strahringer, Susanne}, title = {Current state of IS offshoring research}, series = {M{\"a}ki{\"o}, Juho; Betz, Stefanie; Stephan, Rolf (Eds.): Offshoring of software development.
