The Fearless Organization: From Book to Measurement Tool

In The Fearless Organization (2018), Amy C. Edmondson introduced a groundbreaking concept: psychological safety is the key to high-performing teams. Through decades of research, she demonstrated that when people feel safe to speak up, share ideas, and admit mistakes without fear of negative consequences, organizations thrive. Psychological safety is not just a “nice-to-have” – it is a critical driver of learning, innovation, and collaboration in today’s complex work environments.

From Research to Practice: The Psychological Safety Index (PSI)

Together with Amy C. Edmondson, we translated the core insights from The Fearless Organization into a practical measurement tool: the Psychological Safety Index (PSI).

This validated survey provides clear and actionable insights into the level of psychological safety within a team. By using PSI, leaders, HR professionals, and consultants can move beyond intuition and gain real data on what is helping - or hindering - an environment where people feel safe to contribute.

"Understanding psychological safety isn't enough. You need a way to measure it"
