Facilitation method with published proof
Open Space Technology for Corporate Offsites
Open Space lets participants propose and lead the conversations that matter inside a clear theme, invitation, timebox, and harvest. It is structured self-organization, not an agenda-free event.
The short answer
Use Open Space when a diverse group has real knowledge, several connected questions matter, and participants have permission to choose where they contribute. Do not use it to disguise a decision that leaders have already made or when a formal authority must deliver one prescribed answer.
