Hello!
I'm Scrum Master for two teams. I have the same PO for both. While other team SM/PO's reward their teams with team outings and breakfast, we generally just give praise during Retros and have a strong rapport/relationship.
We love our teams and want to reward them for doing great work. We also know they stress a bit in a crunch (end of project) and want to boost their morale.
What do you all do to reward your teams? Big and small, let me know!
