"Everyone participates, no one dominates"
There are always a mix of extrovert and introverted people in a meeting. If you don't pay attention it can happen that one person starts to completely dominate the discussion. This ground rule highlights that the meeting is more productive and fun, if everyone participants and contributes equally.
E.L.M.O stands for "Enough, let's move on" and can be established as a meeting rule to cut unnecessary discussions. Once stated, anyone in the meeting can say "ELMO!" at any time to indicate that it is time to move on to the next topic.
"Share the air"
This ground rule strengthens the importance of being inclusive and making space for other – often quiet and hesitant – participants. It's everyone's responsibility, to find ways that everyone can contribute their ideas and thoughts to the meeting.
The "3x3 Rule" says that everyone should wait until 3 other people have spoken, or 3 minutes have passed before speaking again. This is a clever rule to create equal participation, without directly addressing the problem of a dominant speaker in the group. Based on the size of the group, this can also be adjusted to the 2x2 or even 4x4 Rule.
"Be the crew, not the passenger"
In general, meetings are better if more people participate and take responsibility for discussions and decisions. "Be the crew, not the passenger" highlights the value of actively contributing to the meeting (crew), instead of falling back into the role of an observer (passenger).
Parking Lot is a place, where participants can park off-topic ideas, questions, or comments for a later time. Establishing this as a ground rule highlights that participants can suggest on their own when to place something on the parking lot in order to keep the meeting on track and on time.
