6 months later, we onboarded 2 senior engineers, 1 junior engineer, and 1 intern.  

Everyone followed our team's internal onboarding document and contributed to it on areas of improvement.  

The senior engineers are leading large projects.  The intern finished their project on time.  Our junior engineer is hitting their stride and making meaningful contributions to the codebase.

I created training around leading the scrum ceremonies and we just finished a full rotation with everyone leading once.  

I'm really happy with how our team culture sponsors autonomy and ownership.
