  3. Agenda • WhyConsistencybetween Process Models? • WhyBehaviouralProfiles? • Howtovalidatetheconcept? • Whatarefurtherapplications? • Whattotakehome?

  4. The Essence of Modeling is model of is model of correspond

  5. Vertical Alignment of Process Models Different purposes for the creation of process models Process automation Staff planning Decision support Business certification Results in significant differences between models describing (parts of) the very same process Slicing of process models Modelling granularity Behavioural differences

  6. Horizontal Alignment of Process Models Different variants of a common process, due to Scope of the process Organisational context IT-landscape No big differences in modelling granularity Still, defined behaviour might be different

  7. Correspondences Model 1 Correspondences Model 2

  8. Agenda • WhyConsistencybetween Process Models? • WhyBehaviouralProfiles? • Howtovalidatetheconcept? • Whatarefurtherapplications? • Whattotakehome?

  9. Simply Comparing Activities is not enough

  10. Existing Notions like Equivalence of Traces are too strict

  11. Behavioural Profiles Need for a behavioural abstraction that is less sensitive to model projections or extensions, respectively Behavioural Profiles capture behavioural characteristics by means of relations between activities Strict order Exclusiveness Interleaving order Based on weak order: weak order between A and B, if there is a trace in which B occurs after A

  12. Behavioural Profiles • Strict order between A and D • Exclusiveness between F and G • Interleaving order between C and E

  13. Behavioural Profile

  14. Properties • Close toTraceEquivalence • Computable in O(n3) for Free Choice nets • Easy tocalculatesimilarity, consistency, etc.

  15. What about Trace Equivalence?

  16. Agenda • WhyConsistencybetween Process Models? • WhyBehaviouralProfiles? • Howtovalidatetheconcept? • Whatarefurtherapplications? • Whattotakehome?

  17. Case Study with SAP Reference Model Computation based on results proved for Petri nets Transformation BPMN to PN EPC to PN UML AD to PN Computation in low polynomial time for certain class of models EPC is sound EPC has unambiguous instantiation semantics

  18. VaryingDegree of Profile Consistency

  19. Consistent but not traceequivalent

  20. Inconsistencies

  21. Agenda • WhyConsistencybetween Process Models? • WhyBehaviouralProfiles? • Howtovalidatetheconcept? • Whatarefurtherapplications? • Whattotakehome?

  22. Change in Process Model 1 • Assumptions • Change can be localized as a single node • Behavioural profile is consistent for aligned nodes • Find boundary nodes for change • Aligned with target model • Closest nodes in strict order preceding and succeeding change

  23. Change Propagation • Derivation of change region supports • Analysis, whether a change should be applied • Application of a change in a consistent manner • Change region might be empty • No flow arc in target model meets requirements for change • Boundary nodes and inter-boundary nodes guide adaptation

  24. Action Patterns Derivation of abstract actions from activities Mining of abstract patterns between activities in a repository Co-occurrences and behavioural relations Usage of these patterns for modelling support

  25. ICoP Architecture • Architecture for the creation of matchers • Multi-step heuristic approach • Reuse of matching components • Adaptable & extendable • Concrete matching components • Exemplify and evaluate the architecture • Generalise existing approaches

  26. Measurement of Compliance Different grouding of behaviouralprofilesforprocessmodelsandforlogs VS Strictness of order relations of Behavioural Profile Subsumption relation Forinstance, interleaving order in processmodelssubsumesstrict order in process log
