This is an exercise I do with leadership teams before we get into strategy and planning sessions. It helps to get them thinking about confidence levels and how they are working as a team to collect and process information. It takes about 20-30 minutes and the focus should be on the discussing the observations and learnings from the process, not getting the answers right.
Here are the two games from Amazon that I mention in the video:
