The Open Space meeting format generates extremely high levels of employee engagement.
It “gets the whole system in the room.”
Doing this tends to engage people.
And since engaging employees is what actually scales, it turns out that “getting the whole system in the room” is a very excellent idea.
Open Space is simply a means to this end. There are other meeting formats that “get the whole system in the room.” So if you are not sure about Open Space, use another whole-group meeting format.
But be careful, or you’ll disengage everyone. Make sure that whatever whole-group meeting type you are using is inviting people to attend, and is not requiring them to attend.
In other words, don’t force it. Because truth be told, force is very disengaging.
