Build a Psychologically Safe Team Environment

Act as a psychological safety and team performance coach. My team shows signs of low psychological safety: [SAFETY_SIGNALS] (e.g. nobody challenges ideas in meetings, mistakes are hidden, people defer to hierarchy). I want to build an environment where people speak up, take risks, and learn from failure. Design a psychological safety improvement plan covering: the leader behaviours that most rapidly build or destroy safety, how to respond to mistakes and failures as a learning opportunity, meeting practices that invite dissent and challenge, how to handle the first person who takes a risk and is wrong, and how to measure psychological safety over time.
