Quick questions on Testing, evaluation and iteration: O-Level Design Studies
2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What are testing with users?Show answer
User testing puts a prototype in front of real members of the target audience and observes them using it. Watching what people actually do is more reliable than asking what they think they would do. Good practice uses realistic tasks ("show me how you would open this"), encourages users to think aloud, and notes where they hesitate, struggle or succeed. Even a handful of testers reveals most major problems.
What is evaluating against criteria?Show answer
Evaluation judges a design against the specification and success criteria set earlier, not against personal taste. By checking each requirement (is it legible? does it suit the audience? does it meet the constraints?), the designer makes an objective assessment of strengths and weaknesses.
