Process Mining as the Superglue between Data and Process

Process mining is rapidly becoming a standard way to analyze performance and compliance problems based on event data. Currently, there are over 35 commercial process-mining tools based on the research by prof. Van der Aalst and his team. Process mining reveals how processes behave “in the wild”. Seemingly simple processes like Order-to-Cash (OTC) and Purchase-to-Pay (P2P), turn out to be much more complex than anticipated. Hand-made models describing behavior (BPMN, UML activity diagrams, EPCs, flow charts, etc.) often fail to capture reality. Process mining connects Business Process Management (BPM) and data-driven approaches such as Data Mining (DM), Machine Learning (ML), Artificial Intelligence (AI), and Business Intelligence (BI) by combining a process-centric view and the evidence hidden in an organization’s databases. In his lecture, I will reflect on the capabilities and limitations of today’s process mining tools. I will also discuss the conversion of data from today’s information systems into event logs showing different viewpoints.

Hybrid Intelligence: To Automate or Not to Automate, That is the Question

There used to be a clear separation between tasks done by machines and tasks done by people. Applications of machine learning in speech recognition (e.g., Alexa and Siri), image recognition, automated translation, autonomous driving, and medical diagnosis, have blurred the classical divide between human tasks and machine tasks. Although current Artificial Intelligence (AI) and Machine Learning (ML) technologies outperform humans in many areas, tasks requiring common sense, contextual knowledge, creativity, adaptivity, and empathy are still best performed by humans. Hybrid Intelligence (HI) blends human intelligence and machine intelligence to combine the best of both worlds. Hence, current and future Business Process Management (BPM) initiatives need to consider HI and the changing boundaries between work done by people and work done by software robots. Consider, for example, the success of Robotic Process Automation (RPA), which demonstrates that gradually taking away repetitive tasks from workers is possible. In this lecture, I will argue that process mining is a key technology to decide what to automate and what not. Moreover, using process mining, it is possible to systematically monitor and manage processes where work is distributed over human workers and software robots.

Revisiting Petri Nets: Adding Objects While Enforcing Lucency

Petri nets play a key role in process mining. One could argue that process mining revived the interest in Petri nets and foundational notions such as the marking equation and region theory. This talk will be composed of two parts: One part is extending Petri nets to deal with multiple types of objects and the other part is about enforcing Petri nets to be lucent, i.e., there cannot be two markings that enable the same set of transitions. Both parts are inspired by requirements from process mining. From an object-centric event log, we want to discover an object-centric Petri net with places that correspond to object types and transitions that may consume and produce collections of objects of different types. Object-centric Petri nets visualize the complex relationships among objects of different types. Whereas object-centric Petri nets extend traditional Petri nets, lucency limits the class of Petri nets to models where states are fully characterized by the transitions they enable. For process mining, this seems to be a relevant property. If the process has two different states enabling the same set of transitions, process discovery becomes more challenging. We can show that all free-choice nets having a home cluster are lucent. It is an open question of how to exploit lucency in process mining. Moreover, it is an open question how to characterize a large class of object-centric Petri nets that is lucent.
