Tutorial: Towards Orthographic Enterprise Architecture Modeling

Enterprise Architecture Modeling (EAM) approaches all use multiple, inter-related views to describe the properties of an enterprise system and its surrounding environment - that is, they are multi-view specification (MVS) approaches. However, there is still little consensus on how such modeling environments should be realized and on the pros and cons of the different fundamental design choices involved in building them. Today´s leading EAMs (e.g. TOGAF, Zach man, Archimate, RM-ODP) all have limitations in the way they support MVS. For example, they all characterize the nature of views by just their type and not their subject. In this tutorial Colin Atkinson will identify the main weaknesses of the current generation of EAMs and present an alternative approach, known as orthographic modelling, which promises to address the identified problems. Orthographic Enterprise Architecture Modeling can subsume existing EAM approaches as special cases.
