Demystifying UX Research, User Testing, and Usability Testing: What Sets Them Apart?

Writer: Di TunneyDi Tunney

Incorporating customer feedback into the UX Design process is becoming increasingly important in the highly competitive world of online marketing! Without it, we run the risk of poor UX, low engagement, higher costs, and even potential business failure.

But how do we approach it and what tools and techniques should we use?


Let’s start by getting clear about the terminology!


UX Research, User Testing, and Usability Testing are three terms that are often confused, but each approach serves a different purpose in the User Experience (UX) Design process.


What’s more, they each involve the use of different tools, techniques and expertise. This article explains the role that each of them plays and when and why they should be used.


1. UX Research


  • Definition: UX research is the broader practice of studying users, their behaviours, needs, motivations, and pain points to inform design decisions. It includes both qualitative and quantitative methods.

  • Purpose:

    • Understand user needs and problems

    • Gather insights before, during, and after product development

    • Guide design decisions based on user data

  • Methods:

    • Primary Research: Interviews, surveys, ethnographic studies

    • Secondary Research: Market analysis, competitor research

    • Behavioural Data: Analytics, A/B testing

  • Example: A UX researcher interviews potential users to understand how they currently solve a problem before designing a new app.


2. User Testing


  • Definition: User testing (or user acceptance testing) is the process of evaluating a product by observing real users as they interact with it. The goal is to validate whether the product meets user expectations and functions as intended.

  • Purpose:

    • Test if users can complete tasks successfully

    • Identify areas where users struggle

    • Ensure the product aligns with user needs

  • Methods:

    • Moderated or Unmoderated Testing (with a facilitator or independently)

    • A/B Testing (comparing different designs)

    • Beta Testing (real-world testing before launch)

  • Example: A company releases a beta version of a mobile app and collects feedback from early users to fix issues before the official launch.


3. Usability Testing


  • Definition: A subset of user testing that specifically focuses on how easily users can complete tasks and interact with a product.

  • Purpose:

    • Identify usability issues

    • Improve efficiency, effectiveness, and satisfaction

    • Optimise user flows and navigation

  • Methods:

    • Think-Aloud Testing (users verbalize thoughts while using the product)

    • Task-Based Testing (users complete predefined tasks)

    • Heuristic Evaluation (experts review the interface based on usability principles)

  • Example: A UX team observes users struggling to find the checkout button on an e-commerce site, prompting a redesign for better visibility.
