Summary

Think aloud testing is a qualitative research method in which participants verbalize their thoughts and actions as they complete tasks on a product or service. During the study, a facilitator, or UX researcher, will guide the participants through a series of tasks and prompt them to speak their thoughts and reasoning out loud. This type of testing is useful for uncovering pain points in a user’s experience and understanding their decision-making process. The data collected during a think aloud study can inform design changes, improve the user experience, and increase overall product satisfaction. To run a successful moderated think aloud study, UX researchers should have strong interpersonal and communication skills, the ability to facilitate discussions, and a deep understanding of the user and their needs.

Data Gathered in Think Aloud Testing
  • Verbal Protocols: This refers to the words and thoughts that the participants verbalize as they interact with the product.
  • User Interactions: This involves recording and analyzing the participant’s actions as they use the product. This could include mouse movements, clicks, scrolling, and other forms of interactions.
  • User Emotions: The researcher might observe and record the participant’s emotional state and reactions during the study.
  • User Frustration and Ease of Use: The researcher can observe and analyze the participant’s frustration levels when using the product and their overall ease of use.
  • Task Completion Time: The researcher can measure the time it takes the participant to complete a specific task using the product, which can give insights into the product’s overall usability.
  • Task Success Rates: The researcher can also record the success rates of participants completing specific tasks, which can give insights into the product’s functionality and the participants’ understanding of it.
Case Study: Charles Schwab

Often in the beginning stages of study planning, I hold a research intake meeting where I invite designers, product owners, and other key stakeholders to brainstorm and understand what it is we want to learn

I determine that a think aloud study is best suited for the research objectives when we just need to get an understanding on how clients feel about the prototype and whether or not it matches their expectations. Then I determine the study schedule and the number of participants. I then find and recruit a representative sample of participants for the study, taking into consideration factors such as demographics, level of affluence, and type of investor.

I develop high-quality, precise tasks to address my team’s research objectives. With my proficiency in utilizing UserZoom and DScout  I am able to conduct thorough and insightful research that will yield the valuable data we need.

I take on the responsibility capturing both qualitative and quantitative data about the participants’ thoughts and performance including factors such as task completion rate and SEQ scores. Once the study is completed, I undergo a deep and extensive analysis of the data, carefully examining the results to draw valuable conclusions and identify actionable insights. My extensive experience in this field has taught me how to identify the most significant patterns and trends, and use them to develop strategies that can have a measurable impact on the user experience

I communicate the results and recommendations of the study in a clear and concise manner to all stakeholders, providing visual aids such as graphs to support the findings. Typically, my recommendations are addressing a specific business objective while also improving user experience. I then work with the development team to implement any recommendations arising from the study to improve the overall usability of the product.
