Open Space (Owen, 2008) is another popular and successful OD practice that does not employ diagnosis. Instead it creates a container that allows for a bottom-up identification of the interests and motivations latent in any large group and helps people with common interests find each other and make agreements about the future. World Café (Brown & Issacs, 2005) has some similarities to Open Space in creating a bottom-up process for identifying what is latent in a large group. In the case of World Café, however, what it helps identify are latent mental models through a more structured process and nuanced facilitation than Open Space.
