5 Data Science University in Den Bosch

6 Process Mining: On the interface between process science and data science

7 As generic as a spreadsheet!

8 Spreadsheet: Killer App for early computers VisiCalc (killer app for Apple II, Oct. 1979) Lotus (killer app for IBM PC 1983) Microsoft Excel (1985)

9 Spreadsheet: Static data

10 Spreadsheet: Static data fact derived

11 Spreadsheet: Static data total value 31 items sold distribution average

12 Spreadsheet: Static data How to analyze operational processes?

13 Process Mining: Spreadsheet for behavior case identifier row = event activity name resource timestamp Input: events ( things that have happened ) Mandatory per event: case identifier activity name timestamp/date Optional resource transaction type costs

14 Process Mining: Spreadsheet for behavior 208 cases 5987 events 74 activities

15 Process Mining: Spreadsheet for behavior batching for activities opstellen eindnota and archiveren

16 Loesje van der Aalst desire line Process Discovery

17 Process Mining: Spreadsheet for behavior process discovery NO modeling needed!

18 Process Mining: Spreadsheet for behavior process discovery NO modeling needed!

19 process model event data Conformance Checking

20 desire line very safe system Conformance Checking

21 Process Mining: Spreadsheet for behavior conformance checking? discovered or hand-made

22 Process Mining: Spreadsheet for behavior conformance checking fitness of 93.5%

23 Process Mining: Spreadsheet for behavior conformance checking final inspection is skipped 40 times

24 Process Mining: Spreadsheet for behavior move on model (something should have happened, but did not) conformance checking move on log (something happened that should not happen)

25 Process Mining: Spreadsheet for behavior NO modeling needed! performance analysis average flowtime is 1.92 months bottleneck

26 Process Mining: Spreadsheet for behavior waiting time of days performance analysis NO modeling needed!

27 Process Mining: Spreadsheet for behavior animating reality real cases NO modeling needed!

28 Process Mining: Spreadsheet for behavior 16 cases are queueing animating reality

29 Deviations Where? Why? time costs

30 How to get started? Event Data Process Mining Tools Data Science Mindset

31 Starting point for process mining: Event data patient activity timestamp doctor age cost 5781 make X-ray Dr. Jones blood test Dr. Scott blood test Dr. Scott blood test Dr. Scott CT scan Dr. Fox surgery Dr. Scott handle payment Carol Hope radiation therapy Dr. Jones case 5541 id radiation activity therapy name timestamp Dr. resource Jones 61 other data
