We often assume that the best performing teams are the ones with the most talent.  In their Aristotle Project, Google tested that assumption over two years, studying more than 180 teams across the organisation. 

They looked at

·      Experience

·      Seniority

·      Personality mix

·      Team size

·      Co-location

·      Management style

None of these reliably predicted performance. 

The factor that did?

Psychological safety.
