Those who have read Professor Edmondson's book "The Fearless Organization" will know that psychological safety is required for team high-performance. Psychological safety is defined as "a belief that one will not be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes".
If you do not feel safe in a group, you are likely to keep ideas to yourself and avoid speaking up, even about risks. Furthermore, if mistakes are held against you, you then look to avoid making mistakes and so stop taking risks, rather than making the most out of your talents. Low psychological safety, therefore, gets in the way of both team performance, innovation, learning, and personal success. For you to be successful in your team, and "as a team", psychological safety is the enabler.
In collaboration with professor Amy C. Edmondson, The Fearless Organization has developed 'The Fearless Organization Scan'. This scan maps how team members perceive the level of psychological safety in their closest context. To improve team performance, it helps to know the Psychological Safety levels in your team, as this is a critical predictor of how your team will learn and work together. By improving the level of psychological safety, you significantly increase the likelihood of team success.
