A Change element is a structured comment that contains information about requested changes to the system/model. This corresponds in some sense to a change in requirements for the current system. A Change element looks the same as a Requirement element:


Enterprise Architect enables you to generate and handle Changes in much the same way as you can handle and color code Requirements. For more information, see the Requirements topic.

You can connect Changes using Realization connectors to model elements that implement the Change, and you can structure a hierarchy of changes using Aggregation.


Change elements can be created with or without an identifying C in the top right corner of the element. To toggle the display of this letter, select or deselect the Show stereotype icon for requirements checkbox on the Options dialog, Objects page.
