Now use the product to complete your chosen task. Do you know where to go next? Does the product provide enough information for you to continue? Why? Why not? Does the product behave as expected? Does the product assume knowledge that the user may not have? Is information carried from one step of the task to the next? Does the product use language that the user will understand? Do users understand whether the action they took has been completed? Make notes on every screen and consider how the journey feels. Is it short and smooth or long and complicated?
