This activity is related to Scrum and can be used to evaluate how happy the team is about the different Scrum elements.
Three flip charts related to the roles, artifacts, and events of Scrum.
Just ask them to put sticky notes on the flip chart how they feel about the different items.
Next step is to discuss the outcome. Why do they think Wow it is great, or Wondering if it is OK, or are Worried about something?
You can use the three W of course for every item you would like to review with the team.
