PerSpect: an Interactive Tool for Performance Pattern Mining

Complex processes can be difficult to understand from event data. Traditional process models effectively visualize control flows, but lack temporal context for performance analysis. To address this, the Performance Spectrum was introduced to map the dynamics of all steps and cases over time. However, its manual interpretation is challenging due to the overlapping patterns and noise. In this tool demonstration paper, we present PerSpect, an interactive, web-based user interface that significantly enhances the original Performance Spectrum approach. To facilitate interactive analysis, the tool automates the targeted detection of established operational behaviors (e.g., batching and FIFO), alongside advanced filtering capabilities and a side-by-side comparison function for evaluating the same segment across different process variants.
