Waiting for Psychological Safety by Vivienne Edgecombe
In her pioneering work in 1999, Amy Edmondson identified the concept of Psychological Safety - a shared belief that the team is safe for interpersonal risk-taking. She discovered that the best-functioning teams are the ones where people feel safe to speak up - to make mistakes, to own up, to share ideas and offer opinions. Since then, organisations such as Google have done their own studies whose findings support this, showing that this one factor could make the biggest difference in how a team and an organisation performs.
