Now, and only now, you can cast a critical eye on the conditions your team has identified. The task is to assess which of the conditions your team believes are the least likely to hold true. In other words, now that you’ve specified what would have to be true for this possibility to be a great idea, which of those conditions worry the team the most and seem the least likely to be true? These conditions constitute the barriers that keep you and the team from choosing that possibility. Until you know if they are true or not, you can’t move ahead.
