1. Whoever comes are the right people.
If 50 people or just one person come to a session, then that is the right number. If nobody shows up, then that is also the right number. This is not a popularity contest!
2. Whatever happens is the only thing that could have.
Open Space is not based on what should happen but builds on what can happen when people come together with passion and commitment to work a common issue. Your expectations about specific outcomes may not be met and things may turn out differently than you had hoped. Whatever happens is right because it is the result of the level of choice, passion and commitment of those participating.
3. Whenever it starts is the right time.
You will know when the session has begun. It will just happen.
4. When it is over it is over.
Similarly, you will know when it is over. You may have scheduled an hour's session but after 30 minutes it feels complete. If that is the case, then declare the session over and move on to something else. People will make the choice to stay or not. The only possible conflict could be finishing in time for the large group session which concludes each day which everyone is asked to attend."
The Law of Two Feet.
This means that you choose where you want to be and for how long during the day by voting with your feet. If you are in a group where you don't feel that you are getting what you want or can contribute what you have to offer, then move somewhere else. Some people prefer to stay in one session from beginning to end, others tend to move from group to group ("butterflies" and "bumblebees") . All are important and contribute to the process. The "bumble-bees" who move from group to group bring insights and ideas from other groups, and provide cross-pollination, while those who remain in the sessions for the duration provide the continuity and stability that allows conversations to build and reach fruition. And anyone may be a "butterfly" for a while, and perch having another conversation, just be yourself!
