* '''Test the prototype''' with the relevant people -- students, faculty, etc., depending on what it is (see below some things to keep in mind as you test). Remember when you had to go out an interview someone on the first week of the challenge? Testing your prototype is similar to that: you might feel apprehensive about showing a prototype that doesn't look very polished to someone else, and that's understandable. Use some of the same strategies you used to set up your interview: introduce yourself and the project, establish a rapport with the other person, encourage him/her to be candid with you, and demonstrate you really care about what he/she says. You will find that people will be incredibly helpful, even flattered that you care about their perspective.

* '''Iterate'''. Based on what you learned about the problem or the solution, you might make a minor modification, learn that the you are solving for the wrong problem or make large changes in your strategy for how you solve the problem. Incorporate your learnings into creating a new prototype and test once again with the same person or different ones.

:Here are some elements to keep in mind when you test your prototype:

* Do NOT sell your idea: Your goal is NOT to convince someone that your idea is good. You want to find out what can be improved.
