Differencegraph - A ProM Plugin for Calculating and Visualizing Differences between Processes

The analysis of di erences and commonalities between process models or between instances which progressed through the model (henceforth referred to as instance tra c) plays an important role in companies. For example, companies are often confronted with di erent versions or variants of a process model and hence need methods to identify redundancies or inconsistencies between them. Di erencegraph is a plugin for ProM which supports the identi cation of di erences and commonalities between process models as well as between their instance tra c. For this purpose a so-called di erence graph between two process models and their instance tra c is calculated and visualized. This generated di erence graph supports decision making in various business cases such as nding deviations between processes.
