Ownership doesn’t transfer until you stop checking over their shoulder.

Handing someone a job while still hovering means they are doing your task, not theirs. As long as you keep checking, the thinking stays with you and so does the responsibility, so they never get the part that makes people care: the risk that it is on them. That is why delegated work often comes back half done. Nobody fully owns what somebody else is still holding.

Give one thing away completely this week, small enough that a bad outcome is survivable. Agree when you will look at it, then do not look before then. Sit with how uncomfortable that is.
