Bad Practice Nr.3: Modeling Minor Details
There will be other business rules when we should still run class
Is it worth putting it all to a diagram?

Best Practice Nr.3: Describing Minor Details
If required number of participants is not available, Head of Training Department can make a decision to run class if There is urgent need to train employees Strategic partners/customers are registered to a class Cancellation costs will be higher than running costs

Bad Practice Nr.4: Slalom in Diagrams
Reading BPMN diagram is obscured by: Long, bended and crossing lines Jumping forth and back in time scale Mixture of primary and secondary scenarios
© No Magic Europe, 2011 17
Best Practice Nr.4: Clear Primary Scenario
Primary scenario should be visible on one line ()
It is recommended to start modeling from primary scenario and add secondary ones afterwards

Bad Practice Nr.5: Reinventing Bicycle
Fresh-baked modelers often invent strange modeling approaches for well-known situations
© No Magic Europe, 2011 19
Best Practice Nr.5: Process Patterns
Process patterns provide bigger modeling components that enable creating simpler and more efficient process diagrams
