I feel like this is missing an acknowledgement that "what a team is capable of" actually depends on the manager! Managing people and priorities takes skills that require practice and learning. A manager that, for example, assigns people to work on things they enjoy working on and avoids excess pressure is going to have a team capable of a lot more than a team where the manager doesn't bother.
So, when I see the list of "reasonable ways for the business to exert influence over the work" I feel like a huge missing one is "help the manager manage their workload and the team better". The manager has a manager and this is ostensibly their responsibility to see and correct
