The authors identify patterns of success in the field of e-shops and virtual relationships. The findings are based on six selected case studies following the methodology developed by Eisenhardt [1989]. The case study approach was used for two reasons: First, a large number of case studies was collected over the last years containing knowledge that had not yet been analysed and interpreted. Second, the authors assume that the research field of e-business and ICT is particularly suited for cross case analysis because of the dynamic development and the need to learn from best practice [Klein/Myers 1999].de-CHCRM330 - Wirtschaft005 - Computer Programmierung, Programme und Daten04B - Beitrag Konferenzschrift107-114
