There are two main types of participatory projects:

Specific creations are often commissioned from an artist. The commission may have a very strict or looser framework, but resident participation is generally central. However, it remains unpredictable and it is not unheard of for artists to take over when participant contribution is too weak. These creations have an especially strong impact on those involved and the process is sometimes more important than the end result.

“Protocol” creations are the most common. Artists produce an outline or canvas that can be transposed and adapted to each location, depending on the participants. The concept of “protocol” highlights the artists’ need to precisely and formally manage participation. This ensures that the artistic process is properly respected.
