Psychological Safety Is Number One Factor in Building High Performance Teams

Psychological safety is the ability to have open vulnerable conversations with respect. It's also about not having a blame culture, so if something goes wrong it's because there was something in the system of work that enabled this thing to happen. A cleaner ended up shutting down a data center, hitting a power switch, which switched off a whole bunch of servers. That meant that there was a global outage for British Airways of their IT systems. So that's the key thing about psychological safety - it's a generative culture where people can challenge authority.
