Now that you’ve created digital wireframes in Adobe XD, it’s time to build, test, and iterate on a low-fidelity prototype. First, you’ll learn how to build a low-fidelity prototype in Adobe XD. You’ll get feedback about your prototype by planning and conducting a usability study. Then, you’ll make changes to your low-fidelity designs based on insights from your research.

Learning Objectives

  • Transition from digital wireframes to digital prototypes
  • Create a low-fidelity prototype in Adobe XD
  • Plan a usability study based on project goals
  • Conduct a usability study for a low-fidelity prototype
  • Modify wireframes and low-fidelity prototypes based on research results
  • Determine how to reduce bias in a usability study


1. Fill in the blank: A designer is developing a retail website and wants to test how well users can add items to the cart. The designer creates a _____ to get feedback on the early design.

  • Prototype (CORRECT)
  • wireframe
  • design framework
  • high-fidelity design

Correct: In this scenario, the design should create a prototype to get feedback on the early design, since they’re interactive structures that allow users to get a basic idea of a product’s functionality.

2. A design team is developing a new app for a photo editor. They want to discuss design options with stakeholders before proceeding to the next phase. How should the team use wireframes at this point of the design stage?

  • To test the design’s functionality and navigation.
  • To develop the interactive version of the final product.
  • To explore and compare multiple ideas quickly before committing to a final design. (CORRECT)
  • To identify and solve problems related to the function of the app.

Correct: Wireframes offer the opportunity to explore and compare multiple design options with minimal content. This helps teams evaluate their options before developing the prototype.


1. As designers work to analyze and synthesize results from their research, what is the next step they should take after finding themes in the data?

  • Organize the data
  • Come up with insights (CORRECT)
  • Gather all data from the usability study in one place
  • Make improvements to the design

Correct: Designers come up with insights grounded in real data and based on the themes they identify in the data.

2. You receive feedback from your usability study on your gym locator app prototype. Some users reported they could not find the map view to locate gyms in their selected city. Which design modification aligns best with this feedback?

  • Add a sort option to the gym locations’ list view by distance
  • Add a filter based on a gym’s amenities
  • Add a link to the Google search page
  • Add a map view option to the search results page (CORRECT)

Correct: You should add a map view option. This addresses the user’s need to locate a gym’s geographical location visually.

3. To determine the research goals of a research plan, what question should you consider?

  • How will the results of the research impact your design decisions? (CORRECT)
  • Who should be involved in the research to ensure you’re using the right metrics?
  • What would indicate that you’re making progress toward your ultimate goal?
  • What led you to conduct this research?

Correct: Research goals should lay out what you’re trying to solve with the design, or what you’d like the outcomes of the research to be. Your research goals should be able to answer the question: How will the results of the research impact your design decisions?

4. It’s important to carefully phrase interview questions during a usability study to reduce the influence of bias. Which of the following questions is a good example of this?

  • Which feature did you like the most?
  • Which product is better?
  • Did you enjoy your experience?
  • What was your experience like? (CORRECT)

Correct: This is a good example of a carefully-phrased interview question. It’s open-ended and doesn’t lead the participant into a specific response.
