I designed a dashboard layout for my company's monitoring application and had a couple of users go through a usability test session while using the application to see how usable to dashboard is.
On one of the user tasks, I wanted them to use a graph on the dashboard to complete the task. However, some of the users used a detailed graph on another page to complete the task. Would this be considered a failed task? Or would it be considered as a completed task since they were able to find the answer they're looking for?
