Explanation

This is how you can have great meetings, stop wasting time and get productive.

The meeting starts timely, no matter if everybody is there. No waiting, no calling, be precise.
The meeting stops timely, no longer meetings should happen, respect the time of others.
Agenda is a plan for the meeting, it gives people idea, why they meet, and lets them prepare. No plan - no meeting.
Minutes - it is recorded, what was discussed and decided to inform others, to not to rediscuss and redecide in the future
PDFs are sent in advance, no time to read 20-200 pages of documentation in the meeting - sets common context.
Action items are very important, otherwise responsibilities are not clear. Artifact/Action + One Responsible Person
The next meeting is so much easier to schedule when people see each other. Do it SAMOSAS too and keep it short amd productive.
