What is it?

Session will happen in early May.

Steps:

• Simona to use the insights to inform specific activities for the workshop
• Carl to lead portion solely on tracing the data (where the metrics come from)
• Simona to facilitate portion to distill closer to ~20 metrics (discussion and dot voting)
