The Fearless Organization: Creating Psychological Safety in the Workplace for Learning, Innovation, and Growth by Amy C. Edmondson book has been out for a couple of years, and the idea of psychological safety has emerged as a critical element of enabling change and growth in organizations. I enjoyed Edmondson discussion of how psychological safety plays a key role in learning, innovation and growth - and lack of it plays a role in limiting these elements. She also provides a high level structure to create and grow psychological safety in an organization.
