Thanks for this Guita. I love how your team grouped these roles into 4 clear sub-groups and beautifully put it into a clear and easy-to-read visual.
I particularly enjoyed the Crazy Dreamer, and Guardian of Peace roles. I think you have nailed the description, accountability and metrics (the latter is the one I have struggled with the most).
I wonder if another metric for the Crazy Dreamer could be something that captures also innovative results coming out of the ideas exploration?
