Usability Issues From Albert and Tullis, “Measuring the User Experience”

• Behaviors that prevent task completion, take someone “off course”

• Expressions of frustration

• Not seeing something that should be noticed

• Performing an action the leads away from task success

• Misinterpreting some piece of content

• Choosing wrong links to accomplish task/navigation
