Usability Testing

Usability testing is a technique to evaluate how easy or difficult users find a company’s product. It can also be used to gauge the intuitiveness or user-friendliness of other aspects of the customer experience, such as navigating a website or completing a trial download. This type of testing is most commonly used to evaluate the usability of the software or product.

Why Usability Testing: Most teams use these tests to learn the following:

  • Ease of use: Is the solution straightforward, self-explanatory, and easy to learn?
  • Efficiency: Are users able to complete each task with a minimum amount of time or clicks?
  • User-friendliness: Is product or software features are easy to use and convenient to identify?

Metrics Should Use in Usability Testing: Normally product managers and designers look for the metrics like time to complete each task, completion rate, error rate.

Usability testing typically involves a two-step process.

  1. The company’s product team observes participants interacting with its product, then speaks with them afterward, and records all of this data.
  2. The team interprets the data based on several metrics, which can be both quantitative and qualitative.

Examples of usability testing metrics include the following:

  • The percentage of the users that were able to complete a given task.
  • The percentage of users who encountered errors in the product.
  • The percentage of users who encountered a specific error in the product.
  • The average time it took for users to complete a given task.
  • The average number of screens, clicks, or other steps it took users to complete a task.
  • The average score users gave to questions about the product’s ease of use, levels of frustration with task completion, or other factors.

Steps of Usability Testing:

  1. Prepare a test plan
  2. Write test case/task
  3. Prepare success metrics
  4. Find target group
  5. Conduct testing
  6. Analyze test result
  7. Prioritize outcome
  8. Improvements or implements as per test result
  9. Notify target group
  10. Analyze success metrics
