In this paper we seek to expand our understanding of how to visualize process model hierarchies. While the information systems community has devoted considerable attention to decomposition as a principle to manage complexity of conceptual models, surprisingly little research has explicitly addressed two relevant factors for understandability of model decomposition in a tool– how the model hiera...

Within the domain of information systems, one of the main technological moves we may presently observe in industrial circles is the paradigm shift from object composition to model transformation. This is happening at a very fast pace. Among the concrete signs of this evolution one may mention the ongoing change at the Object Management Group from OMA (Object Management Architecture) to MDA (Mod...

Both empirical and anecdotal evidence indicate that enterprises across the globe and in various industries, such as finance, healthcare and government, tend to collect hundreds if not even thousands of business process models over time [1-5]. It is quite common that such set of industry-strength business process models includes thousands of activities and further related objects such as data, a...

As a consequence, multiple process models capturing the very same business process coexist. Keeping such models in sync is a challenge within an ever changing business environment: once a process is changed, all its models...
