Psychological Safety: lay the foundation of great culture.

When we say that great culture starts with psychological safety, we’re not talking about perks and parties. We’re talking about:

-Teams that are high-performing, inclusive, and innovative.
-An organization with no hidden problems or pockets of toxicity.
-Employees that exceed expectations and improve without coaxing.
-Applications pouring in while top talent never wants to leave.
-A place where high levels of accountability drive success.

The 4 Stages of Psychological Safety Move You From Theory to Practice.

What is psychological safety? In short, it’s a culture of rewarded vulnerability. When vulnerability is rewarded we spend our time creating value instead of avoiding punishment. The 4 Stages of Psychological Safety™ are a universal pattern that reflects the natural progression of human needs in social settings. These needs exist across demographics, psychographics, nations, and cultures.

1. Inclusion Safety: Can I be my authentic self?

2. Learner Safety: Can I grow?

3. Contributor Safety: Can I create value?​

4. Challenger Safety: Can I be candid about change?

The learn, measure, and improve framework will equip your organization with a shared understanding of psychological safety, an accurate measurement of the level of psychological safety on your teams, and action plans to help teams create cultures of rewarded vulnerability.
