Management is about sensemaking. Management provides the last answer (if one is needed) for 'Why are we doing this?'. It carries accountability for calling 'when to stop', and in the obverse provides belief and is the backstop that 'this can be done'. It therefore also has accountability for changing constraints (money, scope, resource, time) if needed when asked.

Management ties contexts together, so other individuals don't have to ask infinite 'whys', they trust the manager has this covered.

Management can be done by individuals, within the team, or hierarchically. All can work.

Personally strongly disagree with 'managers typically have no skin in the game'. I find it is necessary to care about the outcome and the team and the customer when I work, but YMMV. Do agree that management is a support, though I prefer to use the analogy that it is the 'glue' role
