1. The document discusses trends in business process management, specifically the rise of evidence-based business process management using process mining techniques. 2. Process mining allows companies to analyze process data from event logs to understand their actual processes, quantify the impact of changes, and discover opportunities for improvement. 3. The techniques discussed include process discovery, conformance checking, predictive monitoring, and rule mining to provide insights into deviations, bottlenecks, and other process issues.

- 13. Process Mining: Where is it used? Insurance –Suncorp Australia Health –AMC Hospital, The Netherlands –São Sebastião Hospital, Portugal –Chania Hospital, Greece –EHR Workflow Inc., USA Transport –ANA Airports, Portugal Electronics –Phillips, The Netherlands Government, banking, construction … You next?
- 14. How to? Exploratory method –Discover models –Visualize performance over models –Discover and compare variants Question-driven method –Identify a problem in a process –Decompose into questions –Measure and analyze questions
- 15. The L* Method 1. Plan & Frame the Problem 2. Collect the Data 3. Analyze: Look for Patterns 4. Interpret & Create Insights Create Business Impact Wil van der Aalst. “Process Mining”. Springer, 2012.
- 16. 1. Plan and Frame Problem Frame the problem, e.g. as a top-level question or phenomenon –How and why does customer experience with our order-to-cash processes diverge (geographically, product-wise, temporally)? –Why does the process perform poorly (bottlenecks, slow handovers)? –Why do we have frequent defects or performance deviance? Refine problem into: –Sub-questions –Identify success criteria and metrics Identify needed resources, get buy-in, plan remaining phases
- 17. Planning step – Suncorp Case Oftentimes „simple‟ claims take an unexpectedly long time to complete – To what extent does the cycle time of the claims handling process diverge? – What distinguishes the processing of simple claims completed on-time, and simple claims not completed on time? – What `early predictors‟ can be used to determine that a given `simple‟ claim will not be completed on time? Team of analysts, relevant managers, IT experts Define what a “simple claim” is. Create awareness of the extent of the problem
- 18. 2. Collect the data Find relevant data sources –Information systems, SAP, Oracle (Celonis), BPM Systems –Identify process-related entities and their identifiers and map entities to relevant processes in the process architecture Extract traces –Collect records associated to process entities (perhaps from multiple sources) –Group records by process identifier to produce “traces” –Export traces into standard format (XES) Clean –Filter irrelevant events –Combine equivalent events –Filter out traces of infrequent variants if not relevant
- 19. 3. Analyze – Find Patterns Discover the real process from the logs Calculate process metrics –Cycle times, waiting times, error rates Explore frequent paths Identify and explore ``deviance‟‟ Discover “types of cases” –Classify e.g. by performance
- 20. Suncorp Case Not Ideal Expected Performance Line OK OK Good
- 21. Discriminative Model Discovery Simple “timely” claims Simple “slow” claims Main result Nailed down key activities/patterns associated with slower performance!
- 23. There you are!
- 24. Process Mining: Mastering Complexity Filter –Filter out events (tasks) –Filter out traces Divide by variants (trace clustering) –Many process models rather than one Abstract (zoom-out) –Focus on most frequent tasks or paths –Identify subprocesses and collapse then down Discover rules rather than models

- 36. Oh no! Not again!
- 37. What went wrong? Not all rules are interesting What is “interesting”? –Generally not what is frequent (expected) –But what deviates from the expected Example: –Every patient who is diagnosed with condition X undergoes surgery Y But not if the have previously been diagnosed with condition Z
- 38. Interesting Rules – Deviance Mining Something should have “normally” happened but did not happen, why? Something should normally not have happened but it happened, why? Something happens only when things go “well” Something happens only when things go “wrong”
