Just starting prototyping the traceability between RRC, Design Manager and RTC and Have the following question:

I understand that the derives link is used between RRC and the DM artifact, which is typicall a diagram or set of diagrams. My question concerns the RTC stories and their link to the design. Is it a good practice to link the story to the design? What about the case where we create a story for a sprint, and the sequence diagram, for example, shows the functionality required for that sprint. Link the story to the sequence diagram? Then what happens in the next sprint - a new story is created that builds upon the initial story, and the sequence diagram is updated with new functions? Again link the new story to the new version of the sequence diagram? Seems messy, as the original story points to the most recent version of the sequence diagram. Or should design artifacts link to something higher than the story? Or don't link RTC to design, but get to it thru RRC? Looking for practical guidance to keep the effort for traceabillity simple and manageable.
