What is Process Mining - RPA and Process Mining | UiPath
Process mining is a technique to analyze and track processes. In traditional business process management, it is done with process workshops and interviews, which results in an idealized picture of a process. Process mining, however, uses existing data available in corporate information systems and automatically displays the real process.
