UI IV - Ex 5 CK - Desirability testing

Context:

In this quest, you’ll have to build your own interface.

After designing your own style guide with a moodboard, colors and typography, you can use the series of consistency principles, atomic design structure, the techniques to build you own library and then a series of screens. Step by step, you’ll have built an animated high-fidelity prototype.

The very last step will be to test it on users to detect the impressions they get when they discover your app.

Once again, feel free to get as much inspiration as you need from existing design systems. Dribbble, consistency and structure are your best friends!

Instructions:

Run a desirability test!

The point of this phase is to make sure the values and the spirit you chose for your design.

  • Get back to the values and spirit you chose in Ex 1. Extract 2 to 5 adjectives.
  • Prepare a board with 25+ adjectives, randomly distributed.
  • Show your design to 5 different people, and ask them to select the adjectives among the list from the board that they are inspired with.
  • If the selected adjectives chosen by the users are consistent with the ones you had chosen, congratulations!
  • If the selected adjectives chosen by the users are not consistent, that’s fine! Make 3 suggestions about how to make your moodboard and library evolve.

Deliverables:

  • A desirability testing board with 25+ different adjectives
  • Pictures from the desirability test
  • A PDF document with the outcomes of the desirability test
  • If the outcomes are not consistent with the values, 3 suggestions on how to make the moodboard and design library evolve.

Tips:

  • Avoid confirmation biais: don’t tell them the values and ask them to approve them!
  • Good to know: Desirability testing is great to assess the impressions a design gives to the users. Whereas Usability testing is great to understand what users understand your prototype and how they navigate across the product.
