Most meetings are only necessary because of gaps in shared context. If we all did everything together, there would be no reason for meetings (except with external stakeholders). But teams can easily fall into a a vicious cycle. Inundated by meetings, people begin to isolate themselves, creating a vacuum in shared context that gets filled by more meetings. 

Break the cycle. Pick a meeting that’s being used to share context and find a way to share it earlier and more continuously.
