Ask HN: What kind of meetings do you need to run and with what purpose?

I don't like to participate in meetings that are not prepared, where we spend time discussing the purpose of the meeting or worse where I cannot actually contribute. So to fix this, I took over in multiple places the role of a meeting organiser where I define the purpose, who should be in, do prep work for the meeting, think about who should be there, have a clear agenda and timing and many other sides. I realised recently that I somehow gained a lot of experience in organising some meetings for various purposes. Here are some examples: - process improvements - project management improvements - ideation - customer feedback - improving code reviews - forming a new team - prioritising work - review requirements ... And I was thinking if there is a need or case for writing about how to do good/effective meetings. So I am curious what kind of meetings do you need to run in your daily jobs/work?
