What is process mining?
Process mining is a family of data analysis techniques that reconstruct how business processes actually execute, using event log data from the enterprise systems that run them. The approach is grounded in the recognition that enterprise systems already capture a timestamped record of every action they handle, making it possible to reconstruct actual process flows without relying on workshops or documentation. The result is a factual process map built entirely from operational data.
The field originated at Eindhoven University of Technology through the work of Wil van der Aalst, who developed the foundational Alpha miner algorithm and the ProM framework, an open-source toolset that remains a standard reference for process mining research. The IEEE Task Force on Process Mining, established in 2009, formalized the field and produced the IEEE XES standard for event log exchange.
Process mining works from event logs: timestamped records of every action carried out within a business system. Each record contains three core fields: a case identifier (the process instance), an activity name (what happened), and a timestamp (when it happened). From those records, algorithms reconstruct the actual end-to-end process flow across all cases.
The field covers three analytical types:
Process discovery
Process discovery automatically generates a process model from event log data, showing all variants of how the process actually runs, including exceptions and workarounds that are invisible in designed process models.
Conformance checking
Conformance checking compares the discovered process against an intended reference model, typically a BPMN 2.0 diagram. The output shows where actual execution deviates from design.
Enhancement
Enhancement uses process execution data to improve or extend an existing model with performance metrics, resource utilization, or simulation parameters. The output is a model grounded in real operational behavior, not design assumptions. These three techniques together establish what is actually happening in a process; what to do about it is where process intelligence begins.
What is process intelligence?
Process intelligence is the discipline of collecting, analyzing, and acting on event log data from enterprise systems to understand where business processes deviate from design and support continuous improvement.
Process intelligence builds on process mining as its analytical foundation but extends beyond it. Where process mining produces a factual process map from event data, process intelligence adds the layer that connects that map to action: AI-driven prioritization of improvement opportunities, continuous monitoring to detect regression, and governance structures that link findings to operational change.
The practical distinction is one of scope and continuity. A process mining project has a defined scope and a fixed end date. A process intelligence program runs continuously, with live monitoring, ongoing conformance tracking, and a defined path from findings to change. Those operational differences become clearest when the two are compared directly.
