On July 29th, 2015 Markus Hipp successfully defended his PhD thesis entitled

Navigating in Complex Process Model Collections

at Ulm University, Germany. The whole DBIS team is pleased to congratulate Markus on his successful PhD defense and wishes him all the best for his future and his career. Markus' PhD co-advisors have been Prof. Dr. Manfred Reichert (DBIS), Prof. Dr. Tina Seufert and Prof. Dr. Bela Mutschler (University of Applied Science Ravensburg-Weingarten).

In general, a more flexible navigation and visualization approach is needed that allows process participants to flexibly interact with large process model collections in order to navigate from a standard visualization of a process model collection to a context-specific one. With the Process Navigation and Visualization (ProNaVis) framework, this PhD thesis provides such a flexible navigation approach for large and complex process model collections. Specifically, ProNaVis enables the flexible navigation within process model collections along three navigation dimensions. First, the geographic dimension allows zooming in and out of the process models. Second, the semantic dimension may be utilized to increase or decrease the level of detail. Third, the view dimension allows switching between different visualizations. All three navigation dimensions have been addressed in an isolated fashion in existing navigation approaches so far, but only ProNaVis provides an integrated support for all three dimensions.
