When I was working with the Codesign-it collective, I often heard about the Open Forum (often know as OST, “Open Space Technology”), a method that they were deploying in collaborative innovation projects with clients. In July 2018 I was able to witness how it was used by the members of the collective themselves as part of the “Summer Sprint”, their annual off-site meeting. This was an opportunity to observe more closely the ins and outs of this technology, whose origins can be found in citizen-run open forums.
