Possibly fear that "asking team" builds the dashboard themselves, in a custom way, then asks the "dashboard team" to maintain it.

Although that might still be a time-saver for the backlogged "dashboard team".

I think they (the dashboard team) were worried that if other teams started building their own dashboard, that'd indicate that the dashboard team wasn't that useful. Which could mean they would get fewer promotions or raises, or might even get fired if bad days came. -- So they wanted ownership of all dashboards, whilst actually building them, was less important. (Is my interpretation.)

The new dashboard team manager, who appeared in the end, seemed to be a bit more "get something done" minded though
