Would like the ability to link Story Maps together promoting cross-team visibility and reuse. Our capabilities span multiple delivery teams and program increments. It would be useful to see all the stories through a single map or navigation. Some type of drill-in/used by/hierarchy view, as the maps evolve.
Now I am not solutioning/more theorizing, but if a story map could span workspaces to assemble all the epics/features/, that might be useful approach. Allow Used by links to trigger notifications. We are integrating with Microsoft ADO, and hard to keep tabs on the overall initiative.
I have been utilizing analog User Story Maps for many years. I find them very useful in agile implementations to envision and then elaborate solutions. I find them helpful to assemble stories for stakeholders when work is spread across delivery teams .
