The best prototype is a high fidelity prototype.
Storyboarding is a technique designed to sell finished systems.
The psychology of the user is irrelevant to the UCSD process.
Prototypes elicit information about the general ‘look and feel’ of a system.
Storyboarding does not support formative evaluation.
Usability requirements of a system are what make the system usable.
Limited functionality prototyping supports formative evaluation.
User-centred approaches concentrate exclusively on the functional requirements of systems.
Storyboarding is a cheap and rich way of expressing design ideas.
In vertical prototyping only a small subset of the system’s functionality is tested.
