Implementation - Guidelines





  1. Small groups of three participants each are formed. They are each given a large sheet of paper and three pens.
  2. Each group draws a large triangle on the paper and the participants each write their names, age and other identifying information near the corners.
  3. At each corner there is one participant. Now the participants look for commonalities. These are written either in the centre if all participants share them, or on one of the sides of the triangle if there are commonalities between two people. Special characteristics of each person can be written at the corners.
  4. Finally, the groups can present their posters to each other. For example, one person can introduce another person from his or her group to the whole (work or seminar) group.
