Case Study

We will use the Requirement element, which is a SysML element, in an OV-2 diagram.

Do the following

1. Create an OV-2 diagram.
2. Create a Performer/ Node in the diagram.
3. On the SysML Requirements Diagram toolbar, click the Requirement button.
4. Create a Requirement in the diagram pane.
5. Create the Satisfy relationship between the Performer/ Node and the Requirement.

As you can see in the following figure, we have expressed that the architecture element satisfies the Requirement.
