Will your innovation work as expected? You won't know until you test it in a real-life scenario. Use this role-play activity to look for possible problems with your design.

Do the Challenge: Think of some characters for your role-play. These will be specific people who will interact with your innovation. Read the roles described in the chart below and then identify some characters who can play these roles.

With your teammate, discuss the issues you discovered during the role-playing activity. Discuss each other's solutions and build off each other's ideas to come up with a team revision. Then use the Picasso app or a sheet of paper to revise your innovation's design based on your conversation.
