Measure the Success Rate of User Tasks

Track the success rate for each task you set. Use a stopwatch to track the time and count the number of clicks the user takes to complete each task, whether successfully or not.

If you find that users use too many clicks to complete a task, you might think about modifying existing functions or adding a new one to reduce the number of clicks it takes to complete the task.
