Requirements
You use the 'Requirements' tab of the Responsibilities window or 'Properties' dialog for an element to create requirements that the element is being designed to meet.
Requirements are of two types:
- Internal requirements (responsibilities) and
- External requirements (system requirements, elements connected to the current element by - for example - Realize connectors)
The 'Requirements' tab lists internal requirements, although it provides an option for converting an internal requirement to an external Requirement element. You edit the properties of an external Requirement element through the Properties window for elements.
You can show the internal requirements for an element on a diagram directly, using the element 'Compartment Visibility' function; it is also possible to show inherited requirements in this way.

Requirements |
Lists the names of the requirements associated with the current element. On the Responsibilities window, this panel is displayed by clicking on the drop-down arrow at the end of the 'Requirement' field. It lists only the internal requirements on the element. On the 'Properties dialog both internal and external requirements are listed on the right of the dialog; the external elements are identified by the word 'Yes' in the 'External' column. If you want to convert an internal requirement to an external Requirement element, right-click on the requirement in the list and select the 'Move External' menu option. Right-clicking on an external Requirement element name provides the options to locate the element in the Project Browser or in any diagrams that contain it. |
