5.7.1 Choosing the Order of Test Tasks

Usually you want test users to do more than one task. This means they have to do them in some order. Should everyone do them in the same order, or should you scramble them, or what? Our advice is to choose one sensible order, starting with some simpler things and working up to some more complex ones, and stay with that. This means that the tasks that come later will have the benefit of practice on the earlier one, or some penalty from test users getting tired, so you can't compare the difficulty of tasks using the results of a test like this. But usually that is not what you are trying to do.
