Why BPMN?• 76 implementers• Increasing adoption• Problems with semantics ofmany elements (lanes, tasks,some gateways and events)• Very weak on data and rules• Can’t express many commonsituations, yet has enormousnumber of elements• Missing time dimension• Not suitable for knowledgeprocesses• …. @kvistgaardconsensuscoherenceACDGBWhy BPMN?Based on Consensus/Coherence model of D. Snowden. Source: http://cognitive-edge.com @kvistgaard“A Task is an atomic Activity within a Process flow. ATask is used when the work in the Process cannot bebroken down to a finer level of detail. “BPMN2.0, p. 156…so you can’tTasks are atomic @kvistgaardTasks try to restrict what should be doneduring run time with what is known duringdesign time… and that’s often not muchTasks are restrictive @kvistgaardLet’s see what will happenwithout BPMN tasksTask-free @kvistgaardBPMNWithout tasks, we’ll have…… a leaner BPMN @kvistgaardWithout tasks, our models can……absorb more variety @kvistgaard“The definition of these states, e.g., possiblevalues and any specific semantic are out ofscope of this specification. Therefore, BPMNadopters can use the State element and theBPMN extensibility capabilities to define theirstates.” @kvistgaard @kvistgaard @kvistgaardSTART C1 C2 C3 C4 ENDA BC1. A in START2.
