Looking for UX exercises and activities for our UX team to build skills, grow our team closer, and to have fun. These will be used both for our current team and for new hires during the onboarding process. I'm thinking for the exercises/activities to either be individual or group and take about one hour to complete.
My current list includes sketching, creating storyboards, paper prototyping, and card sorting. I'm looking to see what other activities and ideas are out there.
