Icebreaker (facilitation)
An icebreaker is a brief facilitation exercise intended to help members of a group begin the process of working together or forming a team. They are commonly presented as games to "warm up" a group by helping members get to know each other and often focus on sharing personal information such as names or hobbies.
Although they have become popular over the years, there is a good number of people who dislike them, with some feeling they are a waste of time.
