The problem with these kinds of advices is that it requires ALL teams to have buy-in to this idea.

As soon as a few teams start booking meetings on the hour or half-hour, this whole idea goes out the window and downsides begin to outweigh the positives.

The other downside, as others have mentioned, is that eventually meetings begin to run late.

The best advice about meeting is, in my opinion:

1. Don't have back to back meetings

2. Try to have at least 1 clear point for the agenda

3. Give at least some heads up. Don't pull people into meetings suddenly.
