5 multiple-choice questions marked as you go, and 1 written questions with worked solutions. All on Design methods and processes.
When using anthropometric data for a product meant to be held in the hand, why might a designer target the \( 5^{th} \) to \( 95^{th} \) percentile range rather than the mean average?
During the iterative design process, why is the evaluation of a prototype solution considered a 'cyclic' activity in industrial contexts?
During the feasibility study phase of a project, a designer must interpret statistical data. If the data shows a high standard deviation in the reach measurements of the target user group, what is the most likely design response?
A designer is developing a hand-held kitchen appliance and needs to collect primary data regarding user comfort. Which combination of investigation methods would be most effective for this task?
An office furniture manufacturer is adopting a user-centred design (UCD) approach to develop a new ergonomic chair.
(a) Explain two ways that the use of anthropometric data and percentiles would inform the design proposal for the chair to ensure it is inclusive for a wide range of users. (4 points)
(b) Describe how the iterative design process, specifically the use of prototyping and user feedback, helps to refine the product before mass production begins. (1 point)
