Open Card Sorting Instructions (Understand)
Take 5 minutes and have all participants write down as many ideas as possible on post-its. If people get stuck just have them write down what they think is the most important idea again and again till they come up with more.
Have everyone put their post-its up on the wall and take a min to read over them.
Start to find similarities between all of the ideas as they do that have them move around the post-its into similar groups.
Once there are a couple themes in the groupings add a title card for the group.
