Die Prozess PhilosophenGodfather des Process Mining - Wil van der AalstFolge 54 - Godfather des Process Mining - Wil van der Aalst
In dieser Folge begrüßen wir niemand Geringeren als Professor Wil van der Aalst – den international anerkannten Begründer des Process Mining. Gemeinsam mit Daniel und Matúš taucht er tief in die Ursprünge der Disziplin ein, erzählt von seinen frühen Forschungsideen in den 90ern, der schwierigen Anfangszeit ohne Mitstreiter und seiner Mission, Prozesse endlich datenbasiert sichtbar zu machen. Dabei erklärt er, warum selbst Konzerne wie SAP oder IBM sein Konzept jahrelang ignorierten – und wieso echte Veränderung erst dann passiert, wenn der Druck groß genug ist.

2025-01-301h 22Process Mining CaféExplorative AnalysisWhen you import your data set, you first have to look around and get an overview about your process. Where does it start and where does it end? Can you recognize the expected process? Is there a lot or little variation? Do you see rework or other unexpected patterns? Join us as we discover the loan application process from the BPI 2016 dataset.
2024-12-171h 08Process Mining CaféPreprocessingSome preprocessing tasks can be easily done in Disco. Others require the use of data transformation tools. Xixi has classified the common preprocessing tasks for process mining into six categories: Enriching, Integration, Filtering, Transformation, Reduction, and Abstraction. For each category, we discuss concrete examples from practice.
2024-11-271h 15Process Mining CaféAutomationMany companies use or plan to use automation techniques to reduce manual labor.

2024-03-2656 minProcess Mining CaféHR ProcessesThere is a lot of variability in Human Resources (HR) processes. This is only natural as people are different! And there is different legislation in different countries, different types of benefits, etc. We show two approaches for dealing with this complexity: One bottom-up approach and one top-down approach using the APQC standard process framework.
2024-02-291h 20Process Mining CaféRole of the AnalystHugo walks us through the analysis of the complaints process at the Dutch health insurance provider VGZ. As the data analyst, Hugo could use process mining to bring a fact-based view of the process to the subject matter experts. But he also needed to protect them from jumping to conclusions too early when the data was not good enough yet.
2024-01-301h 39Process Mining CaféActivity-Based CostingIn Activity-Based Costing, indirect costs such as salaries and utilities are tied back to products and services. If you combine Activity-Based Costing with with process mining, then you can allocate costs to activities in your processes and evaluate “buckets of cases” according to their costs for the organization. Willem and Anne show how this works based on a concrete example.
2023-12-191h 02Process Mining CaféData CollectionWhat do you do if you want to do process mining but you don’t have any data? Tobias found an elegant solution: He created a system that allows employees to collect data about process executions in a lightweight and system-independent way. One advantage is that this internal system has privacy considerations built-in.
2023-11-211h 39Process Mining CaféAnalysis TransformationsThe data you find in information systems was not created for process mining purposes. So, often, you need to shape the data to make it suitable. Furthermore, different analysis questions may require particular views on the data. Together with Scott, we look at two concrete examples to illustrate the steps in such transformations.
2023-10-201h 42Process Mining CaféProject PlanningRudi and Anne talk about what it takes to make a good project plan.
