PublicationTowards a Conceptualization of Architectural Support for Enterprise TransformationEnterprise architecture management (EAM) is supposed to be a helpful means to support the management of enterprise transformations, i.e., fundamental changes. However, in current corporate practice, there seems to be no regular application of EAM as leading authority or support service for enterprise transformation. Thus, we examine, which activities need to be conducted in order to manage enterprise transformation. We further identify the needed information inputs for these activities. Based on this foundation, we analyze, which of the information inputs can be provided by EAM. We identify eight major activity areas of enterprise transformation management (ETM). We further identify information inputs that these ETM activities need. Additionally, we identify content elements that EAM can provide by analyzing EAM meta models. Comparing the demand by ETM and the supply by EAM shows that EAM in general provides valuable inputs to the ETM activities but shows weaknesses when it comes to information about individual actors or environmental information. ETM information needs that are strongly supported are e.g. organizational goals, roles and actors. ETM information needs that are weakly supported are e.g. organizational culture, resistances or organizational rituals.

PublicationEnterprise Architecture as a Means for Coordination - An Empirical Study on Actual and Potential PracticeEnterprise architecture management (EAM) is considered a means to guide the alignment of business- and IT-related concerns from an enterprise-wide perspective. Our goal in this paper is to understand by which means EAM supports this coordination task today and potentially in the future. We designed a questionnaire and conducted an empirical study (n=95) with participants from the field of EAM. Based on common coordination mechanisms from literature, we analyze (1) the relation between coordination mechanism and their current EAM support, (2) to what degree participants are aware of opportunities of EAM supporting coordination mechanisms, and (3) what the perceived gap between potential and realized EAM coordination support is. An exploratory factor analysis leads to three factors that represent coordination mechanisms in enterprises. Using these factors, we group participating enterprises in three different clusters: (1) non-coordinators, (2) dominators and (3) negotiators. We find that a similar awareness of opportunities exists in all three clusters, yet there are gaps in the realization of EAM coordination support: non-coordinators show the lowest realization, negotiators the highest. Based on this clustering, we provide implications on further EAM development options.
