How do you define a "good meeting"?

How do you define a "good meeting"?

My meeting expectations:
1. One owner
2. Success is defined in advance
3. No simpler alternative (ie reduce "could have been an email" vibes)
4. Minimum viable attendees (ie only essential people)
5. Minimum viable duration (ie no longer than appropriate)
6. Actionable outcomes (next steps, owners, and deadlines)
