Linking a requirement to a design object

Chapter 7 Linking and Synchronizing Models in PowerDesigner

Linking a requirement to a design object

The following figure shows the links between the Requirements Model and other PowerDesigner models.

For more information on the RQM, see the Requirements Model User's Guide .

You can link requirements to design objects to make sure that each action described in the RQM is implemented by an object during the development process. For example, the Internet Access requirement of the Cyberfridge example can be linked to a Web Service component in an OOM.

You can link a requirement to a design object in any of the following ways:

Using the Add Links to Design Objects in the Traceability Links tab of the requirement property sheet.
Using the Import Design Objects as Requirements command in the Requirements menu.
Using the Export Requirements as Design Objects command in the Requirements menu.

When you link a requirement to a design object, a shortcut of the design object is automatically created in the RQM.

The great benefits of linking requirement to design objects are:

Make sure each the requirement is implemented by at least one design object, you can use the graphical interface of the Traceability Matrix view to do so.
Verify how a change in a requirement impacts design objects using impact analysis.

For more information on impact analysis used with requirements and design objects, see the "Monitoring Links Using Impact Analysis" section.
