Designing and Implementing Business Process Models : ARIS Method manual : Modeling BPMN 2.0 : Process : Activities : Activity type: Task
Activity type: Task
See: Business Process Model and Notation (BPMN).
BPMN 2.0 distinguishes eight task types which are represented by different symbols (see ). Only the abstract task will be available in the symbol bar. The symbols of the remaining seven special task types are not available in the symbol bar, they are handled by the program.
Activity type: Task
When the modeler selects a specific task symbol the software sets the corresponding value of the ARIS attribute type Task type. This attribute type is read-only, but visible; it provides the following values: Abstract task, Business rule task, Manual task, Script task, Send task, Service task, Receive task, and User task.
Mapping the attributes and model associations to ARIS:
