I'm new to facilitating design sprints and have been assigned to lead one for a team working on a marketing campaign in the public health sector. The course materials recommend conducting a head-to-head comparison of different prototypes during the sprint. I'd like to hear from those with experience in this area. What advice or lessons can you share? Additionally, I'm unsure about the ideal participants for the sprint. Any comments or ideas on that would be greatly appreciated. Thank you!
