The highest performing teams share one common trait: Psychological safety
Google conducted an extensive internal study looking into 280 teams. They found one single factor which sets high performing teams apart from team with lesser performance. It’s not team composition based on education, skills or personality traits. The single factor leading to high performing teams is psychological safety, as defined by Amy Edmonson as the believe that you can bring your whole self to work, speak up and voice your opinion without the risk of being penalized.
