To play Spectrum Mapping, start by identifying some topics for which you would like ideas and insights from your participants. Then, ask your team to write down their thoughts, opinions, and ideas on each of the topics.
Once everybody has written their ideas, work together as a group to organize them on the board. To do this, place similar ideas to the left of the topic and more outside-the-box ideas to the right.
Keep doing this until you have covered all topics. The most popular ideas should be on the left, and the least popular ideas on the right.
