Designs and prototypes

Testing and iterating on designs.

Week 6: Testing and iterating on designs. Now that you have a high-fidelity prototype, it’s time to test your mobile app designs by conducting a usability study. You'll analyze the feedback you receive to come up with actionable insights and iterate on your designs. Once your designs are final, you’ll learn how to hand them off to engineers for production. Finally, you’ll showcase all of the artifacts you've created during this certificate program in a case study for your professional UX portfolio.

Analyze and synthesize usability study results


In just four steps, we can turn the observations from our research into actionable insights.
First, we gather all of the data from our usability study in one place. This includes every note and scribble you and the other observers took during the study.
Second, we organize the data. How you organize it is up to you.
Two methods we explored were affinity diagramming and spreadsheet note-taking.
Whatever method you choose, be consistent throughout the study.
Third, we find themes in the data.
One of the key goals of user research is to identify themes or
patterns that are common across participants.
Once you recognize the themes, it's easier to turn the feedback into something actionable.
And finally, we create a list of insights based on the themes.
Strong insights are grounded in real data and
answer the research questions that were laid out in your plan.
Insights should be easy to understand and increase empathy for the user experience.
And the best insights inspire direct action and
help the design team improve the product. Now that you have a list of insights from your usability study,
you're ready to make improvements to your design.

Learn more about identifying when a design is complete

As you continue to iterate, you might wonder how you’ll know when you’ll be finished working on a design project. As you learned in the previous video, there are some important questions to ask yourself to help you decide whether your designs are complete.
Do the designs represent the intended user experience?
Have placeholder text, icons, and imagery been replaced with finalized assets?
Are participants or users able to interact with and interpret the designs without external guidance?
Do the designs follow the existing design system?
Do the designs follow common interaction patterns for their respective platforms?
Do users have a clear path when something goes wrong?
Is the design accessible?
If you can answer “yes” to all of these questions, then you’re in a good place to consider your designs complete! Your designs should fulfill the scope of the project that was set initially and address the user problem that you set out to solve.
