Design can succeed (or fail) in many ways. That said, there are common heuristics that will get you on the right path. In this module, you will conduct heuristic evaluations (HEs) of another learner's paper prototype. The heuristic evaluations will be a way to highlight usability issues, and think about how to improve them.

A journey of a thousand miles begins with a single step. Figuring out what that first step is--and then what the one after that is--can be especially daunting with creative projects. Making forward progress is a lot easier if you write down concrete, actionable goals. This is the main benefit of a development plan. A development plan also helps you track momentum. Are things progressing at the pace you expected? Faster? Slower? Writing a time estimate into your plan and tracking how long it actually took helps you gauge your pace. The first steps of your plan should be the skeleton that forms the core screens of your design.

Crunch time! Your interactive prototypes have to be ready for user testing by the end of this assignment.

In this assignment, you will test your prototype in person with two people to find usability bugs & potential improvements.

You've got data from online users that compares two alternatives. How can you tell whether there is a real difference? Statistical tests, like the CHI-squared test, tell you whether the behavior you observed was likely to have occurred by chance, or whether there's likely to be a real difference between the designs. A/B experiments like these are becoming increasingly popular in industry because experiments help you test your assumptions.

You've done all this great work, and your hard effort has paid off. You've brainstormed, prototyped, designed, iterated, refined, and evaluated. Now's your chance to share your work with the world. This is a great opportunity to tell your design story, and use it as a portfolio to impress your friends, family, and potential employers.
