I don't think it can't be done right, but it's been cargo-culted pretty hard at Fortune 500 companies. But the best scrums I have ever done have just been literally post-it notes on a whiteboard - I think Jira ads a level of complexity that is unsustainable for most orgs.
In my 17 years in the industry I saw working agile twice. Both were small places, both used post-it notes. Both were consultancies, each team dedicated to an independent project.
Everything else, world-class, public, private, consultants or not... was a joke.
I don't think cross-team collaboration works in agile. Either one plans ahead, or everything becomes an unpredictable mess.
Similar, but one place, and same with post-it notes. It went down the shitter when Jira was force fed and all the problems related to keeping them in sync arose.
"b-b-but other teams need visibility of your sprint!" no they don't. I don't think I've looked at other board other than by accident.
