Open Space Technology is a large-group facilitation method developed by Harrison Owen in the mid-1980s. Its defining characteristic is radical simplicity: there is no predetermined agenda, no panel of speakers, and no assigned breakout groups. Instead, participants create the agenda themselves at the start of the event by proposing topics they care about. Sessions form organically, and people move freely between them based on interest and energy.
The method operates under four principles and one law. The principles: whoever comes are the right people; whatever happens is the only thing that could have; whenever it starts is the right time; when it is over, it is over. The Law of Two Feet states that if you find yourself in a situation where you are neither learning nor contributing, use your two feet to go somewhere else. Together, these rules create an environment of self-organization and personal responsibility.
Open Space works best when a genuine issue matters to the participants, when complexity is high, and when diversity of perspective is needed. It is poorly suited to situations where the outcome has already been decided or where management needs to maintain control over the conversation. The method reveals something important about organizations: given the right conditions, people will organize themselves around the topics that genuinely matter, often producing more actionable outcomes than carefully orchestrated conferences.
