The 6-3-5 method is a creativity and idea development method applied in groups. The name refers to its structure: Six participants write down three ideas each on a sheet of paper in 5 minutes. Then, they pass the paper to the next person, who reads the previous ideas and adds three more. This process is repeated six times, resulting in a total of 108 ideas collected. The method aims to quickly generate a broad range of ideas and improve collaboration and inspiration within the group. The ideas can later be evaluated and developed further.
