Go deeper on how you will test your ideas. Think through the specifics using the 5E’s. For bringing a friend, what would ‘entice’ the friend? How will the message best be delivered? What would ‘engage’ them once there? A good way to prototype this is to have visual representation of the options – maybe photos of the offering options printed on cards, including a blank one where the kids could add their own ideas. Similarly, what visitors would be appealing? What tutors? And remember, just like with your ethnographic research, you will want to capture video, photos, and direct quotes.
