Towards inter-organizational Enterprise Architecture Management - Applicability of TOGAF 9.1 for Network Organizations

Network organizations and inter-organizational systems (IOS) have recently been the subjects of extensive research and practice. Various papers discuss technical issues as well as several complex business considerations and cultural issues. However, one interesting aspect of this context has only received adequate coverage so far, namely the ability of existing Enterprise Architecture Management (EAM) frameworks to address the diverse challenges of inter-organizational collaboration. The relevance of this question is grounded in the increasing significance of IOS and the insight that many organizations model their architecture using such frameworks. This paper addresses the question by firstly conducting a conceptual literature review in order to identify a set of challenges. An EAM framework was then chosen and its ability to address the challenges was evaluated. The chosen framework is The Open Group Architecture Framework (TOGAF) 9.1 and the analysis conducted with regard to the support of network organizations highlights which issues it deals with. TOGAF serves as a good basis to solve the challenges of “Process and Data Integration” and “Infrastructure and Application Integration”. Other areas such as the “Organization of the Network Organization” need further support. Both the identification of challenges and the analysis of TOGAF assist academics and practitioners alike to identify further research topics as well as to find documentation related to inter-organizational problems in EAM.
