Diagramming Multi-Level Service-Oriented Enterprise Architecture

Today’s enterprise architecture should incorporate high-level enterprise services that are considered as wrappers of business processes and ICT capabilities. This service-oriented enterprise model consists of a large number of model elements capturing various aspects of the enterprise in question, making any attempt to browse it too cumbersome. Enterprise architecture modeling, therefore, often resorts to a multi-view representation where views are focused and scoped. We define a visual modeling language and develop a supporting tool called SeamCAD that together lay the foundation for further multi-level enterprise modeling techniques. This article is dedicated to our tool realizing a notation schema and reinforcing a distinctive diagramming layout designed to visually capture the hierarchical containment in enterprise models. We demonstrate our real-life EA applications that were constructed thanks to SeamCAD. We report users’ feedback on SeamCAD. © 2019, Springer Nature Singapore Pte Ltd.
