Ex 3. Decide what matters

The key to a successful prototype is:
To spend a little to learn a lot - Melanie Bell-Mayeda of IDEO
That is to say – spend less time, effort and money in order to learn as much as possible as fast as possible.

Design only what is absolutely necessary

Pick the core feature from Exercise 2 that will both:
  • Cause the most pain to your user if it is not done right
  • That is most vital for your user to do in order to achieve their goal
Their goal in this context is the goal they will complete using your service or product.
Focus on testing this element of your service or product first. Once you know this is working, you can move on to your next vital feature.
