  11. 11. Conjectures C1: Structured modeling is positively related to the understandability of the resulting model. C2: A high number of move operations is negatively related to the understandability of the resulting model. C3: Slow modeling is negatively related to the understandability of the resulting model.Tying Process Model Quality to the Modeling Process: Jan Claes – EIS ’12The Impact of Structuring, Movement, and Speed 11/16
  12. 12. Metrics Understandability Measured by perspicuity: “a model that is unambiguously interpretable and can be made sound with only small adaptations based on minimal assumptions on the modeler’s intentions with the model ” Calculation  Correct syntax errors/ambiguities if possible  Transform BPMN model to WF-net  Check soundness of WF-netTying Process Model Quality to the Modeling Process: Jan Claes – EIS ’12The Impact of Structuring, Movement, and Speed 12/16

  15. 15. Conclusion Goal  Understand process of process modeling to improve training/tools Conjectures  C1: Structured modeling is pos. related to understandability  C2: A lot of moves might be neg. related to understandability  C3: Slow modeling is neg. related to understandability Further work  Zoom on structured modeling  Investigate other conjecturesTying Process Model Quality to the Modeling Process: Jan Claes – EIS ’12The Impact of Structuring, Movement, and Speed 15/16
