If your team is not looking at ways to explore ways to overcome these mistakes in the future, this could be a sign that teammates lack psychological safety.
A psychologically safe work environment encourages team members to speak up with ideas, concerns, or recent failures instead of choosing to remain silent.
Psychological safety in the workplace is the belief that the environment is safe for interpersonal risk-taking. It is a belief that one will not be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes.
