Process Mining: Data-driven understanding and optimization of business processes
Process mining is a method for modeling, analyzing, and optimizing business processes – based on event log data from IT systems. Instead of relying on workshops or subjective descriptions, this approach evaluates how processes actually run. Algorithms analyze this data to uncover patterns, deviations, and potential for improvement.
What is Process Mining?
Process mining uses so-called event logs – datasets that document every executed process step action. These logs are generated in information and transaction systems like ERP or CRM and form a complete audit trail ("process trace"). From this data, process mining quantitatively derives process models and process graphs that make the real end-to-end flow understandable.
How Does Process Mining Work?
The process can be divided into three steps:
- Extraction of event log data from transactional or information-based systems.
- Visualization of the end-to-end process – often as a "digital twin" that maps the actual control flow and process variants.
- Identification of Optimization Potential: Improvement and automation opportunities are identified, simulated, and implemented.
Additionally, the IBM source describes that a process graph of the actual workflow is first created. Subsequently, deviations are outlined, and causes for standard deviations are derived. The results are incorporated into visualizations, enabling management and employees to make data-driven decisions.
Process mining can cover several dimensions: control flow and activity sequence, organizational structures, and temporal aspects such as processing times. Additionally, internal process chains can be linked to external interactions – such as customer journeys.
Benefits of Process Mining
- Transparency regarding process variants and actual workflows
- Identification of bottlenecks, unnecessary duplicates, and deviations
- Reduction of cycle times and costs by identifying inefficiencies
- Support for process standardization by aligning with an optimal process model
- Continuous monitoring of process performance using KPIs and SLA-like metrics
Compared to purely qualitative methods – such as elaborate process mapping workshops – Process Mining delivers faster and more objective results because the analysis is based directly on real execution data.
Practical Examples and Use Cases
A key use case is the preparation of automation projects. According to an IBM source, Process Mining can specifically identify areas where Robotic Process Automation (RPA) can be effectively integrated – thereby accelerating automation initiatives. Furthermore, the approach is suitable for process standardization: identified variations can be aligned with an optimal process model and thus gradually reduced.
Distinction from Related Terms
Business Process Management (BPM) often relies on informal data collection methods such as workshops and surveys, resulting in process documentation software. Process Mining, in contrast, directly uses event data from IT systems and operates quantitatively.
Data Mining covers more general analytical tasks – such as pattern recognition or predictions in various contexts. Process Mining is more narrowly defined: it exclusively uses event log data to derive process models from actual operations.
Task Mining complements Process Mining where transactional systems do not provide data. It captures desktop-level, non-transactional activities through additional data collection, thereby making this process level visible as well.
Conclusion
Process Mining combines process knowledge with event data from IT systems to quantitatively model and analyze operations. The reconstruction of real end-to-end processes, the visualization of variations, and the identification of deviations create an objective basis for process improvements. Depending on the results, standardization or automation measures can be derived – for example, through the targeted use of RPA.
