Issue 8440: Section: Appendix A (uml2-rtf) Source: oose Innovative Informatik eG (Mr. Tim Weilkiens, tim.weilkiens(at)oose.de) Nature: Revision Severity: Minor Summary: A use case diagram is a structural diagram. Similar to operations in classes in shows the structure of the system services. Therefore a use case is a specialized Classifier and not Behavior like model elements of all other behavior diagrams (interaction, activity, and state machine). Resolution: Revised Text: Actions taken: March 3, 2005: received issue August 23, 2006: closed issue Discussion: The classification of diagrams is a fuzzy concept to start with and has no precise formal meaning. While it is true that a use case diagram is, in essence a specialized class diagram, most users expect it to be a behavioral diagram – because it deals with functional requirements and because it has traditionally been classified in that category in UML 1. Changing this at this point is likely to introduce confusion.

However I think there will be no confusion when changing the classification. Most of the UML users won't recognize that change since it has no impact in practice. >From my point of view a use case diagram is a structural diagram.
