Walking Through The Tasks
After the task analysis has been made the participants perform the walkthrough by asking themselves a set of questions for each subtask. Typically four questions are asked:
- Will the user try to achieve the effect that the subtask has? Does the user understand that this subtask is needed to reach the user's goal?
- Will the user notice that the correct action is available? E.g. is the button visible?
- Will the user understand that the wanted subtask can be achieved by the action? E.g. the right button is visible but the user does not understand the text and will therefore not click on it.
- Does the user get feedback? Will the user know that they have done the right thing after performing the action?
By answering the questions for each subtask usability problems will be noticed.

Famous quotes containing the words walking and/or tasks:
“The City of New York is like an enormous citadel, a modern Carcassonne. Walking between the magnificent skyscrapers one feels the presence on the fringe of a howling, raging mob, a mob with empty bellies, a mob unshaven and in rags.”
—Henry Miller (1891–1980)
“We are all adult learners. Most of us have learned a good deal more out of school than in it. We have learned from our families, our work, our friends. We have learned from problems resolved and tasks achieved but also from mistakes confronted and illusions unmasked. . . . Some of what we have learned is trivial: some has changed our lives forever.”
—Laurent A. Daloz (20th century)
