My project is on Rational CLM 5.0.2.  We have Use Case artifacts which is comprised of a figure i.e diagram and a narration text. I want to know how to store it in DOORS NG. For example, should I create an artifact type called Use Case and create custom attribute Description ? I understand that DOORS 5.0.2 does not support VISIO diagrams. Can it support diagrams created in Word ? Please advice the best approach to create the artifacts in DOORS NG.
