This paper (in German) is an introduction into the topic of CSR from a German perspective. It provides a brief overview and introduces the different chapters in an edited volume which is a Festschrift for Professor Dr. Gerd Rainer Wagner's 65th Birthday.

The evaluation of the relationship with the customer and related benefits has become a key point for a company’s competitive advantage. The development of customer churn models has increased over the years. However, these models tend to be complex and used on demand, being developed every time the customer analysis is requested. The main contribution of this article is to demonstrate how a backtesting framework can be used for churn evaluation, enabling the validation and monitoring process for the generated churn models.

In this chapter, we introduce a framework that can be used by organizations as a positioning instrument to think of business-ICT alignment decisions in light of the strategic importance of ICT (Information and Communication Technology) in their organization. We make a distinction between organizations where ICT is of high strategic importance and those where ICT is of low strategic importance. Based on this difference we argue that heavily investing in business-ICT alignment processes, structures and roles (PSRs) will not necessarily always be beneficial when ICT is of low strategic importance to the business. Furthermore, organizations that have a minimalist approach to the use of ICT do not necessarily need to invest in business-ICT alignment PSRs. We explain the dynamics and possible migration scenarios of our proposed framework after testing the statistical significance of the relationship between the strategic importance of ICT and the investment in business-ICT alignment. We end this article with a short empirical study which combines survey and case study results. Both the framework and framework dynamics still need further empirical validation, preferably with longitudinal data. Therefore, we stress and acknowledge that many of the discussions in this article are still explorative in nature. However, this article illustrates the possibilities and the need for a more fine-grained approach to business-ICT alignment.
