Business process execution data is analyzed for different reasons such as process discovery, performance analysis, or anomaly detection. However, visualizations might suffer from a number of limitations. Sonification (the presentation of data using sound) has been proven to successfully enhance visualization in many domains. Although there exist approaches that apply sonification for real-time monitoring of process executions, so far this technique has not been applied to analyze process execution data ex post. We therefore propose a multi-modal system, combining visualization and sonification, for this purpose. The concepts are evaluated by a prototypical ProM plugin as well as based on a use case.
