To enable communication between the applications, you must add the Rational Quality Manager server to the remote services list in Rational DOORS, and add the Rational DOORS in a "friend" relationship on the Rational Quality Manager server.
For more information, see this video on YouTube about the Rational DOORS integration with Rational Quality Manager: IBM Rational DOORS and IBM Rational Quality Manager.
To configure this integration, you must perform the following tasks. For more information, see the integration documentation for Rational Quality Manager in the Rational solution for Collaborative Lifecycle Management (CLM) documentation.
