Using Todd's definition of predictability above: "Predictability means you before you perform an action, you can assert with a good degree of accuracy what will happen next."
I'm wondering how the following scenario stands against the notion that usability = predictability. Consider the scenario where a user cannot determine what action to take to initiate a task/process. Is the user really predicting anything at this point? Would you argue that the user has made a prediction as to the fact that they need to perform some action to initiate the process? And that since they cannot validate their prediction by identifying the action to take within the interface the argument predictability = usability holds? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
