ABSTRACT Enterprise Architecture (EA) and methods for the design and em- ployment of EA significantly contribute to the transparency, consistency and eventually to the flexibility of an organization. However, there is hardly any "one-size-fits-all" EA method that is equally effective for a broad range of transformation projects or in a large number of different contexts. Based on an empirical analysis, this paper identifies three relevant EA contingency factors as well as three dominating EA application scenarios as a basis for a situational EA method engineering taking these into account.

    • "An EA repository can support different methodologies and modeling approaches (Schekkerman, 2006, p.202). EA governance: Recent studies have emphasized the importance of formalizing EAM procedures in corporate governance (Boh & Yellin, 2006; Schmidt & Buxmann, 2010; Riege & Aier, 2009; Iyer & Gottlieb, 2004; Winter & Schelp, 2008). A centralized governance structure is required to ensure concordance of different architectural layers and to oversee EAM quality (Boh & Yellin, 2006; Radeke, 2011). "

    • "A key objective of EA is being able to provide a holistic understanding of all aspects of a business, connecting the business drivers and the surrounding business environment, through the business processes, organizational units, roles and responsibilities, to the underlying IT systems that the business relies on. In addition to presenting a coherent explanation of the what, why and how of a business, EA aims to support specific types of business analysis including [11], [12], [13], [14], [15]: alignment between business functions and IT systems; business change describing the current state of a business (as-is) and a desired state of a business (tobe ); maintenance the de-installation and disposal, upgrading, procurement and integration of systems including the prioritization of maintenance needs; quality by managing and determining the quality attributes for aspects of the business such as security, performance to ensure a certain level of quality to meet the needs of the business; acquisition and mergers describing the alignment of businesses and the effect on both when they merge; compliance in terms of a regulatory framework, e.g. Sarbanes-Oxley; strategic planning including corporate strategy planning, business process optimization, business continuity planning, IT management.

    ABSTRACT: Enterprise Architecture (EA) Modelling aims to analyze an organization in terms of its components, IT systems and business processes. Current modelling approaches are based on Service Oriented Architecture (SOA) whereby components publish interfaces of operations that are used via message passing. It has been argued that SOA leads to tight coupling between components and does not handle complex component interactions, with resulting maintenance difficulties. Event Driven Architecture (EDA) is an alternative strategy, based on listening for events, that is designed to address SOA shortcomings. However, there are no EA modelling technologies based on EDA. This paper reviews EA, SOA and EDA, identifies EDA characteristic features and proposes modelling and simulation technologies that are introduced through a simple case study.
