Application of Interorganizational Business Capability Maps in Different Forms of Horizontal Enterprise Architecture Collaboration

In today’s business environment, organizations are continuously confronted with increasing dynamics in the market by competitors introducing new business models or using disruptive technologies to gain advantage. To remain competitive, practitioners and scientists have recognized the relevance of collaboration between organizations in terms of business but also in terms of IT. Centralized top-down enterprise architecture management (EAM) methods have to be adapted in order to support this trend. But empirical studies investigating the introduction and use of interorganizational enterprise architecture (EA) artifacts in this context are still rare. Therefore, we conducted a multiple case study of six EA collaboration initiatives using interorganizational business capability maps (BCM). Based on the results of 12 semi-structured interviews, we categorize and present the goals and use cases in two different forms of horizontal EA collaboration.
