I’m currently in an environment where PowerPoint presentations are extremely rare.
And our meetings wander aimlessly, with no agenda, no sense of what specific point is being discussed, or anything concrete that needs to be decided.
Sometimes the problem is the corporate culture and the people in the room, rather than the tool(s) they choose to use, or not use.
You always have the option of taking control. The prepared man has great advantages in getting his way vs the unprepared. If there is no structure or agenda, make one. If the leaders are weak, become the leader.
Pass out a paper with agenda items, see what happens.
This can upset people, sometimes, but they will at least be forced to respond.
