The company Triamun developed an ASP software solution for the seamless integration of a variety of different partners. The discussion of the integration project comprises four perspectives: business, processes, application, and technology. The case study contains a description of the company, its e-business strategy, parties involved, e-business software solution, and lessons learned. The case shows how a dominant market player created and implemented an industry-wide software solution for an improved electronic data exchange in the healthcare sector. There are, however, limitations to an eventual industry-wide acceptance of the solution especially by players who are not part of the initiator?s business network. The analysis shows that existing governance structures were the key to the acceptance of this software solution.enE-BusinessEDIERP-Systeme330 - Wirtschaft005 - Computer Programmierung, Programme und Daten04B - Beitrag Konferenzschrift2601-2609
