Exposing Delays in Multi-Step Processes by Retrospective Analysis

Multi-step processes are common in healthcare, software development, and other dynamic environments. Managers who monitor processes are overwhelmed by information, and have limited time to investigate data from different viewpoints. We propose the interactive Multi-Step Process Visualization (MSProVis) for retrospective analysis, to expose delays in multi-step processes, and support the comparisons between steps or between actors executing those steps. A usability study with seven users showed that all participants could use MSProVis effectively and rapidly gain insights.
