In Open Space, a facilitator explains the process and then participants are invited to co-create the agenda and host their own discussion groups. Discussions are held in designated areas or separate rooms known as ‘breakout spaces’ and participants are free to move amongst the discussion groups. Each group records the conversations in a form which can be used to distribute or broadcast the proceedings of the meeting (in hard copy, blog, podcast, video, etc). Online networking can occur both before and following the actual face-to-face meetings so discussions can continue seamlessly. In a multi-day Open Space, participants have the opportunity to announce new discussion topics / late-breaking sessions each new morning. At the end of the day (or 2 days or 2.5 days) the full group reconvenes for comments and reflection. This helps participants to re-engage in the full group over the duration of the meeting.
Holy cow! That sounds a lot like open seminars/co-seminars — but with a problem-solving or conference-type focus. Open seminars and Open Space might have a lot to learn from each other!
