You set the action goal. Which task should the test person do with the object? What is the object designed for? The test person is requested to use the product and thus to complete product-related tasks. The handling and operation of the test person with the object is documented and subsequently evaluated. This can be used to derive potential weaknesses for operating errors and possibilities for improvement.
