According to studies, psychological safety is the most important factor for team effectiveness and means “a team climate in which we feel safe to take interpersonal risks” (Prof. A. Edmondson). In such a climate, we feel safe to raise ideas, questions, concerns or mistakes without being punished or shamed. We don't wear a metaphorical mask, but feel comfortable appearing as a whole person.  We feel accepted and comfortable as individuals and are therefore ready to make a full contribution. We can develop our full potential as a team or organization and are highly adaptable. Participative forms of collaboration such as self-organization in particular require a high level of psychological security in order to succeed.
