1. Pair up project groups with different challenges, so that no pair have the same or similar challenges.
2. Have group 1 present their challenge, as simple as they can. They are not allowed to give any deeper context or any deep insight into the challenge. Just an outline of where the challenge is observed, and who it’s a problem to.
3. Group 2 comes up with ideas based solely from what they think they know about the challenge, they are not allowed to search for any information regarding the challenge, only come up with ideas based on their initial unbiased knowledge. All ideas are written down.
4. After 15-20minutes the groups switch so Group 2 presents the challenge, and group 1 come with their unbiased ideas.
