Data objects are unable to specify states.[1] Symbol [1]     Silver, B. (2009). BPMN Method and Style: A levels-based methodology for BPM process modeling and improvement using […]


Because a group is not an activity or a flow object, it cannot connect to sequence or message flows. Furthermore, groups are not constrained by pool and lane restrictions. [1] Symbol (2009).
