Having one great idea is not enough.

You want multitude of ideas. The whole concept of this sole genius who suddenly comes up with a brilliant idea does not exist; let’s just kill that notion right away. Sure, there might be super smart geniuses out there, but the greatest genius rarely works alone. If not with other people, but always amongst other great ideas. Or even bad ones.

This is the basics of any innovation - it's not until it is tested, prototyped and practiced that it actually becomes a real invention.

So give the participants the stamina and the courage to hear each other out. And see if there is any possibility to develop the thoughts and ideas that come up during the workshop.

You will find the participants more eager to co-create together, once they understand that it’s not the quality of the idea, but the very multitude of ideas that matters.

Exercise "Continuation"

An easy way of demonstrating this concept, of building on each others ideas, is to do a classic child play called "Continuation". You arrange the participants to sit in a ring and then everyone get to speak one sentence each. The aim is to build a story together, you could even have someone writing it down. Make sure no one is thinking to hard, keep the sentences coming in an even flow. Suddenly you all have build a story together, just like building on each others ideas, this story would not have happened if it was not for the groups joint contribution. This exercise is also possible to do quietly with a paper that every participant writes their sentence on, and then folds and hands over to the person sitting next in line. After a couple of turns, unfold the paper and read out loud. Great fun, even if it is a child's game..
