The feedback nobody gives
The first two lessons in this course covered what feedback does and how to give it well. Both assume someone is willing to say the thing. In most teams the most valuable feedback flows upward or sideways: a mistake noticed by a peer, a plan a junior person doubts, a process everyone quietly works around. That feedback is the easiest to withhold.
Amy Edmondson named the condition that decides whether it gets said. In a 1999 study in Administrative Science Quarterly of 51 work teams in a manufacturing company, she defined team psychological safety as
Definition: "a shared belief held by members of a team that the team is safe for interpersonal risk taking."
She found psychological safety was associated with learning behaviour, such as asking for feedback, discussing errors and seeking help, and that learning behaviour in turn mediated the link between psychological safety and team performance. The facilitation course on AnyLearn applies the same research to retrospectives; here the focus is the feedback itself.
