Unconferences often use variations on the Open Space Technology format/method developed by Harrison Owen in the mid 1980’s. Owen’s 1993 book Open Space Technology: a User’s Guide discussed many of the techniques now associated with unconferences, although his book does not use that term.
Typically at an unconference, the agenda is created by the attendees at the beginning of the meeting. Anyone who wants to initiate a discussion on a topic can claim a time and a space. Unconferences typically feature open discussions rather than having a single speaker at the front of the room giving a talk, although any format is permitted. This form of conference is particularly useful when the attendees generally have a high level of expertise or knowledge in the field the conference convenes to discuss.
