When IBM® Rational® DOORS® and IBM Rational Focal Point™ are integrated, you can prioritize and build upon data from both products.
You can use Rational Synchronization Framework to synchronize data between a Rational Focal Point module and a Rational DOORS module without direct user intervention. Then, in Rational Focal Point, you can use the synchronized data to prioritize requirements from Rational DOORS. You can also capture and prioritize user requirements in Rational Focal Point and then send them to Rational DOORS to further develop them as system requirements, specifications, designs, and supporting artifacts.
