In addition to measuring the success rate, it’s crucial to consider how much users struggled to find the right information by looking at the time spent on tasks. The time spent metric indicates how long it took users to locate the correct category, providing insight into the mental effort involved.

If users took a long time to complete a task, even if they were ultimately successful, it may indicate that the process was challenging and mentally taxing. This can reveal areas where your navigation structure may be confusing or inefficient.

To analyze task times, start by comparing the times for various tasks in your study. Identify which tasks took significantly longer and investigate why.
