Participants were asked to post potential solution ideas and vote on them using colored stickers to determine which ideas they wanted to further develop. The ideas were then sorted on a poster to collectively decide which were feasible, not yet feasible, or ordinary based on the voting in order to select the original ideas to focus on developing further.

1. Hang all the solution ideas up and let the participants
vote using different colour stickers.
Sort the ideas on the poster and decide together which
ideas you want to further develop.
