The standing rule
In many companies, meetings are held with everybody standing up
because it leads to decisions being reached more quickly (see point 1). At
Washington University, studies showed that when they are standing, people
react more readily with enthusiasm, whereas when they are sitting, they
tend towards scepticism.
The smartphone rule
No smartphones during the meeting. Notes should be made by hand. Even
the White House supposedly followed this rule under Barack Obama.
If you want to call a family meeting, just turn off the WiFi router and wait
in the room where it is located.
