OMG Exam OMG-OCUP2-ADV300 Topic 8 Question 6 Discussion

To orchestrate multiple actions within UML, a modeler should use StructuredActivityNodes:

A . Extending Behavior and adding desired Actions is not specifically about coordinating multiple actions; it's about defining new behaviors.

B . Correct. StructuredActivityNodes are a part of UML that provides a mechanism to group a set of actions together and manage the data flows between them, thus coordinating the actions.

C . Using the standard Action and adding desired tag values does not inherently coordinate actions.

D . Extending Action and specifying constraints to be relaxed or removed does not directly relate to coordinating other actions.

UML Specification: Activities section, which describes the use of StructuredActivityNodes.

The use of StructuredActivityNodes for coordinating actions is elaborated in the UML 2.5 Documentation under Activity Diagrams.
