Will the user try to achieve the right effect? In other words, would the user even know that this is the goal they should have? If not, there’s a design flaw.Will the user notice that the correct action is available? If they wouldn’t notice, you have a design flaw.Will the user associate the correct action with the effect that the user is trying to achieve? Even if they notice that the action is available, they may not know it has the effect they want. If the correct action is performed, will the user see that progress is being made toward the solution of the task? In other words, is there feedback that confirms the desired effect has occurred? If not, they won’t know they’ve made progress. This is a design flaw.
These steps are helpful to keep in mind when conducting a cognitive walkthrough because it can act as a 'toolkit' when I'm unsure of what I need to be measuring. Having parameters when doing tests is also helpful for a beginner like me, who has only done one or two in the past. It's interesting to think about how these steps address whether the design is intuitive enough from different angles.
