These objects can be an additional source of information about requirements, either in the making of a requirements model, or as a result of a requirement satisfaction.
You can perform several actions concerning design objects in a requirements model:
Attach design objects in other models to a requirement – see Linking Requirements with Design Objects
Export requirements to other models as design objects – see Exporting Requirements as Design Objects
Import design objects in other models as requirements – see Importing Design Objects as Requirements
