The optimal is for everyone not to do the reading, there’s time for it in the meeting. And in terms of time management, managers can be in back to back meetings for a large portion of the day and this provides focus time to not just wing it.
Wouldn't it be optimal to have read, understood and thought about it before the meeting? Although this probably never happens, except maybe if you go full async and request a thoughtful response from everybody before a meeting might happen.
Right I shouldn’t have said optimal, it’s the Nash equilibrium though.
