Facilitator Tips

Emphasize the "freestanding" requirement. Announce time remaining regularly. Connect the exercise to the design process. Sometimes, teams get frustrated, remind them it's about learning.

Variations

Try a mini version. Focus on a smaller scope or different constraints. This provides a fresh perspective and may resonate better with some groups.
