Each group is assigned a task and consists of around one hundred participants. Membership can be seen as an honorary assignment, a call to action or a break in the daily routine. Participation is entirely on a voluntary basis, all group members are anonymous and there is no requirement or expectation of feedback or documentation.

The purpose of performing each group's task is to create an opportunity for the participants to get a different view of their own everyday life. The task creates space for irratitonal kinds of actions that may directly or indirectly affect people in the members' environment. At mid 2022, approx. 1200 people, or 0.12 per thousand of Sweden's population, was a member of one of Kanslibyråns working groups.
