We have a design team that is working with 6 other teams as a shared service.
The design team, needs to be able to see and control the state of the stories in the other 6 backlogs. We've done that much (tag stories as "design", so that they appear in Design team's board).
What we've found is that these stories inherit their parent boards' workflow states, so in the design team's kanban board, when we move a story, depending on its workflow steps, the appropriate steps are shown on the board under "In Progress".
Are there any best practices for working in this fashion?
The aim here is for the design team to control stories found in other backlogs, to avoid creating their own stories.
