Usability testing aims to have volunteers use the app, gather data from their experiences, and figure out how to make the app better. However, it’s not guaranteed to perfect the product. Sometimes, errors in the process can skew the results.

In this article, we’ll cover seven common mistakes in usability testing and how to avoid them.

1. Not Defining a Clear Business Objective

A frequent mistake is not setting a clear goal for the usability test. It’s crucial to know why you’re testing. This clarity helps ensure the test yields useful results for improving the product. Knowing your business goal guides the entire testing process. Without it, the test may lack direction, wasting time and resources. By asking specific questions, like whether the test will reduce customer support calls, you can enhance the test’s effectiveness.

2. Selecting Inappropriate Tasks

The tasks you ask users to perform are the foundation of usability testing. To save time and money, focus on key issues. Ensure tasks align with your test’s goals and adjust them based on your company’s standards. Focus on areas of your site that may already be problematic to ensure tasks are relevant and effective.

3. Recruiting Unsuitable Participants

It’s essential to recruit the right participants for your test. The demographics of your testers should match those of your actual users to get relevant feedback. For instance, if your site targets adults aged 30-40, testing with teenagers won’t yield useful insights. Accurate feedback from your target audience can significantly improve your site’s design or conversion rates.

4. Lack of Dedicated Resources

Often, usability testing suffers from insufficient time and resources, preventing the full potential of the findings from being realized. Analyzing feedback thoroughly requires significant effort. Consider employing a dedicated UX research team or outsourcing to ensure comprehensive analysis and actionable results.

5. Failing to Effectively Communicate Results

A usability test can produce a lot of data, but it’s useless if it doesn’t reach the design team. Creating detailed reports is one way to address this, but often these reports go unread. Effective communication strategies include review sessions, email discussions, and interactive workshops to ensure findings are understood and acted upon.

6. Not Testing Potential Solutions

Before starting your usability test, have a plan for using the data. If the test identifies a problem, be ready with a solution to test immediately. The challenge is knowing which solution will work without further testing. Organize a round of testing for potential solutions in advance, ready to be canceled if no issues arise.

7. Testing to Confirm Preconceived Ideas

Confirmation bias can lead to designing tests that validate your own ideas rather than objectively assessing user interaction. Usability testing should be about understanding how users interact with your product, not confirming your own ideas. Stay neutral and let the data guide your conclusions.


Usability testing requires a significant investment of time and resources. Understanding what you aim to achieve and dedicating the necessary resources can help avoid common pitfalls and ensure a successful usability testing effort.
