I have seen managers create task funnels for requests coming from other teams. They assume this has fixed all coordination issues. Later I see engineers having to engage week-after-week out to other teams for coordination. Things are not in place. People don't respond, coordination "APIs" don't work as documented. I have seen individuals blamed for dependency failures that they had no part in. I rarely see the obvious solution: Why don't managers spend day-in-day-out coordinating work across teams/orgs/corporate barriers? Instead of doing coordination, managers seem to be spending more time doing HR stuff like vacations, performance calibrations, documenting ways to blame engineers. They create such APIs and think their job is done. Why? How? What a severe deadweight in the company.
