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.
- The company’s product team observes participants interacting with its product, then speaks with them afterward, and records all of this data.
- 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:
- Prepare a test plan
- Write test case/task
- Prepare success metrics
- Find target group
- Conduct testing
- Analyze test result
- Prioritize outcome
- Improvements or implements as per test result
- Notify target group
- Analyze success metrics
